Pills

Compound

Active ingredient: Drospirenone + Ethinylestradiol (Drospirenone + Ethinylestradiol). Concentration of active substance (mg): Drospirenone 3 mg, ethinyl estradiol 0.02 mg

Pharmacological effect

Pearl index: 0.31 (upper 95% confidence interval: 0.85). The contraceptive effect of the drug is based on the interaction of various factors, the most important of which are inhibition of ovulation and changes in the endometrium. The drug DIMIA 24+4 is a combined oral contraceptive (COC) with a combination of ethinyl estradiol and the progestin drospirenone. At a therapeutic dose, drospirenone also has antiandrogenic and weak antimineralocorticoid effects. Does not have estrogenic, glucocorticoid and antiglucocorticoid activity. Thus, drospirenone has a pharmacological profile close to the natural hormone progesterone. Clinical studies have revealed that the antimineralocorticoid properties of the drug DIMIA lead to a weak antimineralocorticoid effect. It has antiandrogenic activity, which leads to a reduction in the formation of acne and a decrease in the production of sebaceous glands, and does not affect the increase in the formation of sex hormone-binding globulin caused by ethinyl estradiol (inactivation of endogenous androgens).

Pharmacokinetics

Drospirenone Absorption: When taken orally, drospirenone is rapidly and almost completely absorbed. The maximum serum concentration of drospirenone, equal to 37 ng/ml, is achieved 1-2 hours after a single oral dose. Bioavailability ranges from 76 to 85%. Food intake does not affect the bioavailability of drospirenone. Distribution: After oral administration, serum levels of drospirenone decrease with a final half-life of 31 hours. Drospirenone is observed to bind to serum albumin, but the drug does not bind to sex hormone binding globulin (SHBG) or corticosteroid binding globulin (CBG). Only 3 - 5% of total serum concentrations of active substance are present as free steroid. The ethinyl estradiol-induced increase in SHBG does not affect the binding of drospirenone to serum proteins. The average apparent volume of distribution of drospirenone is 3.7 ± 1.2 l/kg. Metabolism. Drospirenone is actively metabolized after oral administration. The main metabolites in the blood plasma are the acid form of drospirenone, formed by opening of the lactone ring, and 4,5-dihydro-drospirenone-3-sulfate, both formed without the participation of the P450 system. Drospirenone is metabolized to a small extent by cytochrome P450 3A4, and is capable of inhibiting this enzyme, as well as cytochrome P450 1A1, cytochrome P450 2C9 and cytochrome P450 2C19 in vitro. Elimination. The rate of metabolic clearance of drospirenone in serum is 1.5±0.2 ml/min/kg. Drospirenone is excreted only in trace amounts unchanged. Drospirenone metabolites are excreted in feces and urine in a ratio of approximately 1.2: 1.4. The half-life for excretion of metabolites in urine and feces is approximately 40 hours. Steady-state concentration: During one treatment cycle, the maximum steady-state serum concentration of drospirenone (approximately 70 ng/ml) is achieved after 8 days of treatment. Serum concentrations of drospirenone increase by approximately 3 orders of magnitude due to the relationship between terminal half-life and dosing interval. Ethinyl estradiol. Absorption: Ethinyl estradiol, after oral administration, is rapidly and completely absorbed. The maximum concentration in the blood serum after a single dose of 33 pg/ml is achieved after 1-2 hours. After first-pass conjugation and first-pass metabolism in the small intestine and liver, the absolute bioavailability is 60%. Concomitant food intake reduced the bioavailability of ethinyl estradiol in approximately 25% of people studied, whereas no similar changes were observed in other people. Distribution: Serum ethinyl estradiol levels decline in two phases, with a terminal pharmacokinetic phase characterized by a half-life of approximately 24 hours. Ethinyl estradiol binds to albumin about 98.5% and induces an increase in the concentration of SHBG and DSG in the serum. The apparent volume of distribution is approximately 5 l/kg. Metabolism: Ethinyl estradiol undergoes presystemic conjugation in the mucosa of the small intestine and in the liver. Ethinyl estradiol is primarily metabolized by aromatic hydroxylation, resulting in the formation of a variety of hydroxylated and methylated metabolites, presented both as free metabolites and as conjugates with glucuronic and sulfuric acids. Ethinyl estradiol is completely metabolized. The rate of metabolic clearance of ethinyl estradiol is 5 ml/min/kg. Elimination: Ethinyl estradiol is practically not excreted unchanged. Ethinyl estradiol metabolites are excreted in urine and bile in a ratio of 4: 6. The half-life of the metabolites is approximately 1 day. The elimination half-life is 20 hours. Steady-state concentration: Steady-state concentration is achieved during the second half of the treatment cycle, with serum ethinyl estradiol levels increasing by a factor of approximately 2.0-2.3. Selected Populations: Effect on Renal Function: Steady-state serum drospirenone levels in women with mild renal impairment (creatinine clearance CLcr = 50-80 ml/minute) were comparable to those in women with normal function kidneys (CLcr more than 80 ml/minute). Serum drospirenone levels were on average 37% higher in women with moderate renal impairment t (CLcr = 30-50 ml/minute) compared with those in women with normal renal function. Drospirenone therapy was well tolerated by women with both mild and moderate renal impairment. Drospirenone treatment did not have a clinically significant effect on serum potassium concentrations. Effect on Liver Function: In a single-dose study, total clearance (CL/f) in volunteers with moderate hepatic impairment was reduced by approximately 50% compared to subjects with normal hepatic function. The observed decrease in clearance of drospirenone in volunteers with moderate hepatic impairment does not lead to any significant differences in serum potassium concentration. Even with diabetes and concomitant treatment with spironolactone (two factors that can precipitate hyperkalemia in the patient), there was no increase in serum potassium concentrations above the upper limit of normal. It can be concluded that the combination of drospirenone/ethinyl estradiol is well tolerated in patients with moderate hepatic impairment (Child-Pugh class B). Ethnic groups: There were no clinically relevant differences in the pharmacokinetics of drospirenone or ethinyl estradiol between Japanese and Caucasian women.

Indications

Oral contraception.

Contraindications

The drug Dimia, like other combined oral contraceptives, is contraindicated in any of the following conditions: thrombosis (arterial and venous) and thromboembolism currently or in history (including thrombosis, deep vein thrombophlebitis, pulmonary embolism, heart attack myocardium, stroke, cerebrovascular disorders). Conditions preceding thrombosis (including transient ischemic attacks, angina) currently or in history. Multiple or severe risk factors for venous or arterial thrombosis, including complicated lesions of the heart valve apparatus, atrial fibrillation, cerebral vascular disease or coronary artery disease. uncontrolled arterial hypertension, major surgery with prolonged immobilization, smoking over the age of 35, obesity with a BMI greater than 30 kgm2. Hereditary or acquired predisposition to venous or arterial thrombosis, for example, resistance to activated protein C, antithrombin III deficiency, protein C deficiency, protein S deficiency, hyperhomocysteinemia and antiphospholipid antibodies (presence of antibodies to phospholipids - antibodies to cardiolipin, lupus anticoagulant). Pancreatitis with severe hypertriglyceridemia, currently or in history. Existing severe liver disease (or history) provided that liver function is not currently normal. Severe chronic or acute renal failure. Liver tumor (benign or malignant) currently or in history. Hormone-dependent malignant neoplasms of the genital organs or breast, currently or in history. Bleeding from the vagina of unknown origin. History of migraine with focal neurological symptoms. Lactase deficiency, lactose intolerance, glucose-galactose malabsorption, lapp lactase deficiency (lactase deficiency in some peoples of the North). Pregnancy and suspicion of it. Lactation period. Hypersensitivity to the drug or any of the components of the drug.

Precautionary measures

Use of any combined oral contraceptives is associated with an increased risk of venous thromboembolism comparable to that without use. The additional risk is greatest during the first year of combined oral contraceptive use. Venous thromboembolism is fatal in 1-2% of cases. Epidemiological studies also associate COC use with an increased risk of arterial thromboembolism (myocardial infarction, transient ischemic attack). In women taking combined oral contraceptives, extremely rare cases of thrombosis of other blood vessels, such as the hepatic, mesenteric, renal arteries and veins, the central retinal vein and its branches, have been described.

Use during pregnancy and breastfeeding

If pregnancy occurs while taking DIMIA, the drug must be discontinued immediately. Epidemiological studies have not revealed an increase in the risk of childbirth for women who took COCs before pregnancy, nor a nitrateogenic effect when COCs were unintentionally taken during pregnancy. No such studies have been conducted with the drug. COCs may affect lactation as they can reduce the amount and change the composition breast milk. Therefore, the use of COCs cannot be recommended until a breastfeeding woman has completely stopped breastfeeding. Small amounts of contraceptive hormones or their metabolites may be excreted in milk during COC use. These amounts may affect the child. Features of the effect of the drug on the ability to drive a vehicle and potentially dangerous mechanisms. No studies have been conducted studying the effect of the drug on the ability to drive a car and work with mechanisms with an increased risk of injury.

Directions for use and doses

The tablets should be taken daily, at approximately the same time, with a small amount of water, in the order indicated on the blister pack. The tablets are taken continuously for 28 days, 1 tablet. days Taking tablets from the next package begins after taking the last tablet from the previous package. Withdrawal bleeding usually begins 2-3 days after starting placebo tablets (last row) and does not necessarily end by the start of the next pack. How to start taking Dimia. If hormonal contraceptives have not been used in the last month, Dimia should be taken on the first day of the menstrual cycle (i.e., on the first day of menstrual bleeding). It is possible to start taking it on days 2-5 of the menstrual cycle; in this case, additional use of a barrier method of contraception is necessary during the first 7 days of taking the tablets from the first package. Switching from other combined contraceptives (combined oral contraceptives in the form of tablets, vaginal ring or transdermal patch) You should start taking Dimia the day after taking the last inactive tablet (for products containing 28 tablets) or the day after taking the last active tablet from the previous package (possibly the next day after the end of the usual 7-day break), for drugs containing 21 tablets per package. If a woman uses a vaginal ring or transdermal patch, it is preferable to start taking Dimia on the day of their removal or, at the latest, on the day when a new ring is planned to be inserted or the patch is replaced. Switching from contraceptives containing only progestogens (mini-pills, injections, implants), or from an intrauterine system (IUD) that releases progestogens. A woman can switch from taking a mini-pill to taking Dimia on any day (from an implant or from an IUD on the day of their removal, from injectable forms of drugs - on the day when the next injection was due), but in all cases it is necessary to use additional barrier method of contraception during the first 7 days of taking the pills. After an abortion in the first trimester of pregnancy. Taking Dimia can be started as prescribed by a doctor on the day of termination of pregnancy. In this case, the woman does not need to take additional contraceptive measures. After childbirth or abortion in the second trimester of pregnancy. A woman is recommended to start taking the drug 21-28 days after childbirth (provided she is not breastfeeding) or abortion in the second trimester of pregnancy. If use is started later, the woman should use an additional barrier method of contraception during the first 7 days after starting to take Dimia. With the resumption of sexual activity (before starting to take Dimia), pregnancy should be excluded.

In women with hereditary angioedema, exogenous estrogens may induce or worsen symptoms of angioedema.

Overdose

Symptoms: nausea, vomiting, slight vaginal bleeding in young girls. Treatment: symptomatic.

Interaction with other drugs

In patients with renal failure, simultaneous administration of drospirenone and ACE inhibitors or NSAIDs (non-steroidal anti-inflammatory drugs) does not have a significant effect on serum potassium levels. However, the simultaneous use of DIMIA and aldosterone antagonists or potassium-sparing diuretics has not been studied. In this case, it is necessary to study the level of potassium in the serum during the first cycle of taking the drug. Note: Concomitant use of drugs should be discussed to identify possible drug interactions. Laboratory research: Taking hormones for contraception may affect the results of certain laboratory tests, including biochemical parameters of liver function, thyroid gland, adrenal glands and kidneys, as well as levels of plasma transport proteins, such as corticosteroid binding globulin and lipid/lipoprotein fractions, indicators of carbohydrate metabolism, coagulation and fibrinolysis. Changes usually occur within laboratory limits. Due to its slight antimineralocorticoid activity, drospirenone increases the activity of plasma renin and aldosterone.

special instructions

If any of the conditions/risk factors listed below currently exist, the potential risks and expected benefits of using COCs should be carefully weighed in each individual case and discussed with the woman before she decides to start taking the drug. If any of these conditions or risk factors worsen, intensify, or appear for the first time, a woman should consult her doctor, who may decide whether to discontinue the COC. Circulatory system disorders: Epidemiological studies have shown that the incidence of VTE (venous thromboembolism) in women without risk factors for VTE taking combined oral contraceptives with low dose estrogens (less than 50 mcg ethinyl estradiol) is approximately 20 cases per 100,000 women per year (for levonorgestrel- containing “second-generation” COCs or up to 40 cases per 100,000 women per year (for desogestrel/gestodene-containing “third-generation” COCs). This compares with figures of 5 to 10 cases per 100,000 women not using contraceptives and 60 cases per 100,000 pregnancies. Use of any combined oral contraceptive is associated with an increased risk of venous thromboembolism comparable to that without use. The additional risk is greatest during the first year of combined oral contraceptive use. Venous thromboembolism is fatal in 1-2% of cases. Epidemiological studies have also associated COC use with an increased risk of arterial thromboembolism (myocardial infarction, transient ischemic attack). In women taking combined oral contraceptives, extremely rare cases of thrombosis of other blood vessels, such as the hepatic, mesenteric, renal arteries and veins, the central retinal vein and its branches, have been described. Symptoms of venous or arterial thrombosis/thromboembolism or cerebrovascular disease may include: unusual unilateral pain and/or swelling of an extremity, sudden severe chest pain, with or without radiation to the left arm, sudden shortness of breath, sudden coughing fit, any unusual, severe, prolonged headache, sudden partial or complete loss of vision, diplopia, slurred speech or aphasia, dizziness, loss of consciousness with or without a seizure, weakness or severe loss of sensation suddenly appearing on one side or in one part of the body, movement disorders, symptom of "acute abdomen" " The risk of complications associated with venous thromboembolism when taking COCs increases: with age in the presence of a family history (venous or arterial thromboembolism ever in close relatives or parents at a relatively young age); if a hereditary predisposition is suspected, a woman needs to consult a specialist before prescribing a COC after prolonged immobilization, major surgery, any leg surgery or major trauma. In these situations, it is recommended to stop taking the drug (in the case of planned surgery, at least four weeks before it) and not to resume taking it for two weeks after the end of immobilization. Additionally, it is possible to prescribe antithrombotic therapy if taking the tablets has not been stopped within the recommended period of obesity (body mass index more than 30 mg/m2) there is no consensus on the possible role of varicose veins and thrombophlebitis of the superficial veins in the onset or progression of venous thrombosis. The risk of arterial thromboembolic complications of thrombosis or cerebrovascular disease in women taking COCs increases: with age in smokers (women over 35 years of age are strictly not recommended to smoke if they want to use COCs), with dyslipoproteinemia, with hypertension, with migraines, with heart valve diseases, with fibrillation atria. The presence of one of the serious risk factors or multiple risk factors for arterial or venous disease, respectively, may be a contraindication. Women using COCs should contact their doctor immediately if they experience symptoms of possible thrombosis. In cases of suspected nathrombosis or confirmed thrombosis, COC use should be discontinued. It is necessary to select an adequate method of contraception due to the teratogenicity of anticoagulant therapy (coumarins). The increased risk of thromboembolism in the postpartum period should be taken into account. Other diseases that are associated with severe vascular pathology include diabetes , systemic lupus erythematosus, hemolytic uremic syndrome, chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis) and sickle cell anemia. An increase in the frequency and severity of migraine during the use of COCs (which may precede cerebrovascular events) may be grounds for immediate discontinuation of these drugs. An increased risk of cervical cancer with long-term use of combined oral contraceptives has been reported in some epidemiological studies. Its connection with the use of combined oral contraceptives has not been proven. Controversy remains regarding the extent to which these findings are attributable to sexual behavior and other factors such as human papillomavirus (HPV). A meta-analysis of 54 epidemiological studies demonstrated that there was a slightly increased relative risk (RR=1.24) of developing breast cancer diagnosed in women who were using combined oral contraceptives at the time of the study. Its connection with the use of combined oral contraceptives has not been proven. The observed increased risk may be a consequence of earlier diagnosis of breast cancer in women using combined oral contraceptives. Breast cancer in women who had ever used combined oral contraceptives was clinically less severe than in women who had never used such drugs. In rare cases, during the use of combined oral contraceptives, the development of benign liver tumors has been observed, and in extremely rare cases, the development of malignant liver tumors. In some cases, these tumors lead to life-threatening intra-abdominal bleeding. If severe abdominal pain, liver enlargement, or signs of intra-abdominal bleeding occur, the differential diagnosis of a woman taking COCs should consider the possibility of developing a liver tumor. Other Conditions: The progestin component in DIMIA is an aldosterone antagonist with potassium-sparing properties. In most cases, potassium levels are not expected to increase. But in a clinical study of some patients with mild to moderate renal impairment, concomitant use of potassium-sparing drugs slightly increased serum potassium levels when taking drospirenone. Therefore, it is recommended to check serum potassium levels during the first cycle of treatment in patients with renal failure whose pre-treatment serum potassium levels were at the upper limit of normal and who are additionally using potassium-sparing drugs. In women with hypertriglyceridemia, or a family history of this disease, an increased risk of developing pancreatitis while taking combined oral contraceptives cannot be excluded. Although slight increases in blood pressure have been reported in many women taking combined oral contraceptives, clinically significant increases have been rare. Only in rare cases is immediate discontinuation of COCs justified. If, while taking COCs and existing arterial hypertension, persistently or significantly elevated blood pressure does not adequately respond to antihypertensive treatment, you should stop taking the COC. The following conditions have been reported to develop or worsen both during pregnancy and while taking combined oral contraceptives, but have not been shown to be associated with combined oral contraceptives: jaundice and/or pruritus associated with cholestasis, gallstone formation, porphyria, systemic lupus erythematosus , hemolytic uremic syndrome, Sydenham's chorea, herpes of pregnancy, hearing loss associated with otosclerosis

In this article you can read the instructions for use of the drug Dimia. Reviews of site visitors - consumers of this medicine, as well as the opinions of specialist doctors on the use of the hormonal contraceptive Dimia in their practice are presented. We kindly ask you to actively add your reviews about the drug: whether the medicine helped or did not help get rid of the disease, what complications were observed and side effects, perhaps not stated by the manufacturer in the annotation. Dimia analogues in the presence of existing structural analogues. Use for contraception in women and prevention of unwanted pregnancy, as well as during breastfeeding. Composition of the drug.

Dimia- is a combined monophasic oral contraceptive containing drospirenone and ethinyl estradiol. In terms of its pharmacological profile, drospirenone is close to natural progesterone: it does not have estrogenic, glucocorticoid and antiglucocorticoid activity and is characterized by pronounced antiandrogenic and moderate antimineralocorticoid effects. The contraceptive effect is based on the interaction of various factors, the most important of which are inhibition of ovulation, increased viscosity of cervical secretions and changes in the endometrium. The Pearl index, an indicator reflecting the pregnancy rate in 100 women of reproductive age during a year of contraceptive use, is less than 1.

Compound

Ethinyl estradiol + Drospirenone + excipients.

Pharmacokinetics

Drospirenone

When taken orally, drospirenone is quickly and almost completely absorbed from the gastrointestinal tract. Bioavailability - 76-85%. Concomitant use with food does not affect the bioavailability of drospirenone. Drospirenone binds to serum albumin and does not bind to sex hormone binding globulin (SHBG) or corticosteroid binding globulin (transcortin). Only 3-5% of total serum concentrations of drospirenone exist as free steroids. Drospirenone is actively metabolized after oral administration. Drospirenone is excreted only in trace amounts unchanged. Drospirenone metabolites are excreted by the kidneys and intestines with an excretion ratio of about 1.2:1.4.

Ethinyl estradiol

When taken orally, ethinyl estradiol is absorbed quickly and completely. Absolute bioavailability as a result of first pass conjugation and first pass metabolism is approximately 60%. Concomitant food intake decreased the bioavailability of ethinyl estradiol in approximately 25% of the patients studied; others had no changes. Ethinyl estradiol is a substrate of presystemic conjugation in the mucous membrane of the small intestine and in the liver. Ethinyl estradiol is primarily metabolized by aromatic hydroxylation, resulting in a wide range of hydroxylated and methylated metabolites, which are present both in free form and as conjugates with glucuronic acid. Unchanged ethinyl estradiol is practically not excreted from the body. Metabolites of ethinyl estradiol are excreted by the kidneys and through the intestines in a ratio of 4:6.

Indications

oral contraception.

Release forms

Film-coated tablets in a blister of 24 pieces white and 4 pieces of green (28 tablets in total).

Instructions for use and dosage regimen

How to start taking Dimia

If hormonal contraceptives have not been used in the last month, Dimia should be taken on the first day of the menstrual cycle (i.e., on the first day of menstrual bleeding). It is possible to start taking it on days 2-5 of the menstrual cycle; in this case, additional use of a barrier method of contraception is necessary during the first 7 days of taking the tablets from the first package.

Switching from other combined contraceptives (combined oral contraceptives in the form of tablets, vaginal ring or transdermal patch)

You should start taking Dimia the next day after taking the last inactive tablet (for drugs containing 28 tablets) or the next day after taking the last active tablet from the previous package (possibly the next day after the end of the usual 7-day break) - for drugs , containing 21 tablets per package. If a woman uses a vaginal ring or transdermal patch, it is preferable to start taking Dimia on the day of their removal or, at the latest, on the day when a new ring is planned to be inserted or the patch is replaced.

Switching from progestogen-only contraceptives (mini-pills, injections, implants) or from a progestogen-releasing intrauterine system (IUD)

A woman can switch from taking a mini-pill to taking Dimia on any day (from an implant or from an IUD on the day of their removal, from injectable forms of drugs - on the day when the next injection was due), but in all cases it is necessary to use additional barrier method of contraception during the first 7 days of taking the pills.

After an abortion in the 1st trimester of pregnancy

Taking Dimia can be started as prescribed by a doctor on the day of termination of pregnancy. In this case, the woman does not need to take additional contraceptive measures.

After childbirth or abortion in the 2nd trimester of pregnancy

A woman is recommended to start taking the drug 21-28 days after childbirth (provided she is not breastfeeding) or abortion in the 2nd trimester of pregnancy. If use is started later, the woman should use an additional barrier method of contraception during the first 7 days after starting to take Dimia. With the resumption of sexual activity (before starting to take Dimia), pregnancy should be excluded.

Taking missed pills

Skipping a placebo tablet from the last (4th) row of the blister can be ignored. However, they should be discarded to avoid inadvertently prolonging the placebo phase. The instructions below only apply to missed tablets containing active ingredients.

If the delay in taking the pill is less than 12 hours, contraceptive protection is not reduced. A woman should take the missed pill as soon as possible (as soon as she remembers), and the next pill at the usual time.

If the delay exceeds 12 hours, contraceptive protection may be reduced. In this case, you can be guided by two basic rules:

Taking the pills should never be interrupted for more than 7 days;
To achieve adequate suppression of the hypothalamic-pituitary-ovarian axis, 7 days of continuous tablet use are required.

In accordance with this, women can be given the following recommendations:

Days 1-7

A woman should take the missed pill as soon as she remembers, even if this means taking two pills at the same time. She should then take the pills at the usual time. Additionally, a barrier method such as a condom should be used for the next 7 days. If sexual intercourse occurred in the previous 7 days, the possibility of pregnancy should be considered. The more pills you miss and the closer this skip is to the 7-day break in taking the drug, the higher the risk of pregnancy.

Days 8-14

A woman should take the missed pill as soon as she remembers, even if this means taking two pills at the same time. She should then take the pills at the usual time. If during the 7 days preceding the first missed pill, a woman took her pills as prescribed, there is no need for additional contraceptive measures. However, if she missed more than 1 tablet, an additional method of contraception (barrier - for example, a condom) is required for 7 days.

Days 15-24

The reliability of the method inevitably decreases as the placebo pill phase approaches. However, adjusting your pill regimen can still help prevent pregnancy. When following one of the two regimens described below, and if in the previous 7 days before skipping the pill the woman complied with the drug regimen, there will be no need to use additional contraceptive measures. If this is not the case, she should follow the first of two regimens and use additional precautions for the next 7 days.

1. A woman should take the last missed pill as soon as she remembers, even if this means taking two pills at the same time. She should then take the tablets at the usual time until the active tablets are gone. 4 placebo tablets from the last row should not be taken; you should immediately start taking tablets from the next blister pack. Most likely, there will be no withdrawal bleeding until the end of the second package, but spotting or withdrawal bleeding may be observed on the days of taking the drug from the second package.

2. A woman can also stop taking active tablets from the started package. Instead, she should take placebo tablets from the last row for 4 days, including the days she missed tablets, and then start taking tablets from the next pack.

If a woman misses a pill and subsequently does not experience withdrawal bleeding during the placebo pill phase, the possibility of pregnancy should be considered.

Use of the drug for gastrointestinal disorders

In case of severe gastrointestinal disorders (for example, vomiting or diarrhea), absorption of the drug will be incomplete and additional contraceptive measures will be required. If vomiting occurs within 3-4 hours after taking the active tablet, you must take a new (replacement) tablet as quickly as possible. If possible, the next tablet should be taken within 12 hours of the usual tablet-taking time. If more than 12 hours have passed, it is recommended to proceed as directed when missing tablets. If a woman does not want to change her usual pill regimen, she should take an additional pill from a different pack.

Delay of menstrual-like withdrawal bleeding

To delay bleeding, the woman should skip the placebo tablets from the started pack and start taking drospirenone + ethinyl estradiol tablets from the new pack. The delay can be extended until the active tablets in the second package run out. During the delay, a woman may experience acyclic heavy or spotting bleeding from the vagina. Regular use of Dimia is resumed after the placebo phase.

To shift bleeding to another day of the week, it is recommended to shorten the upcoming phase of taking placebo tablets by the desired number of days. When the cycle is shortened, it is more likely that the woman will not have menstrual-like “withdrawal” bleeding, but will have acyclic heavy or spotting bleeding from the vagina when taking the next package (the same as when the cycle is lengthened).

Carefully

risk factors for the development of thrombosis and thromboembolism: smoking under the age of 35 years, obesity, dyslipoproteinemia, controlled arterial hypertension, migraine without focal neurological symptoms, uncomplicated valvular heart disease, hereditary predisposition to thrombosis (thrombosis, myocardial infarction or cerebrovascular accident at a young age any of the immediate relatives);
diseases in which peripheral circulatory disorders may occur: diabetes mellitus without vascular complications, systemic lupus erythematosus (SLE), hemolytic-uremic syndrome, Crohn's disease, ulcerative colitis, sickle cell anemia, phlebitis of the superficial veins;
hereditary angioedema;
hypertriglyceridemia;
severe liver disease (until normalization of liver function tests);
diseases that first appeared or worsened during pregnancy or against the background of previous use of sex hormones (including jaundice and/or itching associated with cholestasis, cholelithiasis, otosclerosis with hearing impairment, porphyria, history of herpes during pregnancy, minor chorea (Sydenham disease), chloasma;
postpartum period.

Use during pregnancy and breastfeeding

Dimia is contraindicated during pregnancy.

If pregnancy occurs while using Dimia, it should be stopped immediately. Extensive epidemiological studies have shown neither an increased risk of birth defects in children born to women who took combined oral contraceptives (COCs) before pregnancy, nor a teratogenic effect of COCs if taken unintentionally during pregnancy.

According to preclinical studies, it is impossible to exclude undesirable effects that affect the course of pregnancy and fetal development due to the hormonal action of the active components.

The drug Dimia can affect lactation: reduce the amount of milk and change its composition. Small amounts of contraceptive steroids and/or their metabolites may be excreted in milk during COC use. These amounts may affect the child. The use of Dimia during breastfeeding is contraindicated.

Use in children

The use of the drug before menarche is not indicated.

special instructions

If you have any of the conditions/risk factors listed below, the benefits of taking COCs should be assessed individually for each woman and discussed with her before starting use. If an adverse event worsens or if any of these conditions or risk factors occur, the woman should contact her doctor. The doctor must decide whether to stop taking the COC.

Circulatory disorders

Taking any combined oral contraceptive increases the risk of venous thromboembolism (VTE). The increase in the risk of VTE is most pronounced in the first year of a woman's use of a combined oral contraceptive.

Epidemiological studies have shown that the incidence of VTE in women with no risk factors who took low doses of estrogens (< 0.05 мг этинилэстрадиола) в составе комбинированного перорального контрацептива, составляет примерно 20 случаев на 100 000 женщин-лет (для левоноргестрелсодержащих КПК "второго поколения") или 40 случаев на 100 000 женщин-лет (для дезогестрел/гестоденсодержащих КПК "третьего поколения"). У женщин, не пользующихся КПК, случается 5-10 ВТЭ и 60 беременностей на 100 000 женщин-лет. ВТЭ фатальна в 1-2% случаев.

Data from a large, prospective, 3-arm study showed that the incidence of VTE in women with or without other risk factors for venous thromboembolism using the combination of ethinyl estradiol and drospirenone, 0.03 mg + 3 mg, was the same as the incidence of VTE in women using levonorgestrel-containing oral contraceptives and other PDAs. The risk of venous thromboembolism when taking Dimia has not currently been established.

Epidemiological studies have also revealed an association between COC use and an increased risk of arterial thromboembolism (myocardial infarction, transient ischemic events).

Very rarely, thrombosis of other blood vessels, such as veins and arteries of the liver, mesentery, kidney, brain or retina, has occurred in women taking oral contraceptives. There is no consensus regarding the connection of these phenomena with the use of hormonal contraceptives.

Symptoms of venous or arterial thrombotic/thromboembolic events or acute cerebrovascular accidents:

unusual unilateral pain and/or swelling of the lower extremities;
sudden severe pain in the chest, regardless of whether it radiates to the left arm or not;
sudden shortness of breath;
sudden onset of cough;
any unusual severe, long-lasting headache;
sudden partial or complete loss of vision;
diplopia;
impaired speech or aphasia;
vertigo;
collapse with or without partial epileptic seizures;
weakness or very noticeable numbness that suddenly affects one side or part of the body;
movement disorders;
"sharp" stomach.

Before starting to take COCs, a woman should consult a specialist.

The risk of venous thromboembolic disorders when taking COCs increases with:

increasing age;
hereditary predisposition (venous thromboembolism has ever occurred in siblings or parents at a relatively early age);
prolonged immobilization, extensive surgery, any surgery on the lower extremities or major trauma. In such situations, it is recommended to stop taking the drug (in the case of planned surgery, at least four weeks in advance) and not to resume until two weeks have passed after complete restoration of mobility. If the drug is not stopped promptly, anticoagulant treatment should be considered;
obesity (body mass index more than 30 kg/m2);
lack of consensus on the possible role of varicose veins and superficial thrombophlebitis in the appearance or exacerbation of venous thrombosis.

The risk of arterial thromboembolic complications or acute cerebrovascular accident when taking COCs increases with:

increasing age;
smoking (women over 35 years of age are strongly advised to quit smoking if they want to take COCs);
dyslipoproteinemia;
arterial hypertension;
migraine without focal neurological symptoms; obesity (body mass index more than 30 kg/m2);
hereditary predisposition (arterial thromboembolism ever in siblings or parents at a relatively early age). If a hereditary predisposition is possible, a woman should consult a specialist before starting to take COCs;
damage to the heart valves;
atrial fibrillation.

Having one major risk factor for venous disease or multiple risk factors for arterial disease may also be a contraindication. Anticoagulant therapy should also be considered. Women taking COCs should be properly instructed to inform their physician if symptoms of thrombosis are suspected. If thrombosis is suspected or confirmed, COC use should be discontinued. It is necessary to start adequate alternative contraception due to the teratogenicity of anticoagulant therapy (indirect anticoagulants - coumarin derivatives).

The increased risk of thromboembolism in the postpartum period should be taken into account.

Other medical conditions associated with adverse vascular events include diabetes mellitus, systemic lupus erythematosus, hemolytic uremic syndrome, chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis), and sickle cell disease.

An increase in the frequency or severity of migraine while taking COCs may be an indication for immediate discontinuation of combined oral contraceptives.

Tumors

The most significant risk factor for developing cervical cancer is infection with the human papillomavirus. Some epidemiological studies have reported an increased risk of cervical cancer with long-term use of combined oral contraceptives, but there remains controversy regarding the extent to which these findings are attributable to confounding factors such as testing for cervical cancer or use of barrier methods of contraception.

A meta-analysis of 54 epidemiological studies found a small increase in the relative risk (RR = 1.24) of breast cancer in women who were currently taking COCs. The risk gradually decreases over 10 years after stopping COC use. Since breast cancer rarely develops in women under 40 years of age, an increase in the number of breast cancer diagnoses among COC users has little effect on the overall likelihood of developing breast cancer. These studies did not find sufficient evidence of causality. The increased risk may result from earlier diagnosis of breast cancer in COC users, the biological effects of COCs, or a combination of both factors. Diagnosed breast cancer in women who had ever taken COCs was clinically less severe, which was due to early diagnosis of the disease.

Rarely, benign liver tumors have occurred in women taking COCs and, even more rarely, malignant tumors liver. In some cases, these tumors were life-threatening due to intra-abdominal bleeding. This should be taken into account when making a differential diagnosis in the event of severe abdominal pain, liver enlargement, or signs of intra-abdominal bleeding.

Other states

The progestogen component of the drug Dimia is an aldosterone antagonist that retains potassium in the body. In most cases, an increase in potassium levels is not expected. However, in a clinical study in some patients with mild to moderate kidney disease who were taking potassium-sparing medications, serum potassium levels increased slightly while taking drospirenone. Therefore, it is recommended to monitor serum potassium levels during the first cycle of treatment in patients with renal failure whose pre-treatment serum potassium concentrations were at the upper limit of normal and, especially, while taking potassium-sparing drugs.

Women with hypertriglyceridemia or a hereditary predisposition to it may have an increased risk of pancreatitis when taking COCs.

Although slight increases in blood pressure were observed in many women taking COCs, clinically significant increases were rare. Only in these rare cases is it justified to immediately stop taking the COC. If, when taking COCs in patients with concomitant arterial hypertension, blood pressure constantly increases or significantly elevated blood pressure cannot be corrected with antihypertensive drugs, taking COCs should be discontinued. After normalization of blood pressure with the help of antihypertensive drugs, COC use can be resumed.

The following diseases appeared or worsened both during pregnancy and when taking COCs, but the evidence of their relationship with taking COCs is inconclusive: jaundice and/or itching associated with cholestasis, gallstones; porphyria; systemic lupus erythematosus; hemolytic-uremic syndrome; rheumatic chorea (Sydenham's chorea); herpes during pregnancy; otosclerosis with hearing loss.

In women with hereditary angioedema, exogenous estrogens may induce or worsen symptoms of edema.

Acute or chronic liver disease may be an indication to stop taking COCs until liver function tests normalize. Recurrence of cholestatic jaundice and/or pruritus associated with cholestasis, which developed during a previous pregnancy or with earlier use of sex hormones, is an indication for discontinuation of COCs.

Although COCs may influence peripheral insulin resistance and glucose tolerance, changing the treatment regimen in patients with diabetes mellitus while taking COCs with low hormone content (containing< 0.05 мг этинилэстрадиола) не показано. Однако следует внимательно наблюдать женщин с сахарным диабетом, особенно на ранних стадиях приема КПК.

While taking COCs, an increase in endogenous depression, epilepsy, Crohn's disease and ulcerative colitis was observed.

Chloasma may occur from time to time, especially in women who have a history of chloasma during pregnancy. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet light while taking COCs.

Drospirenone + ethinyl estradiol coated tablets contain 48.53 mg of lactose monohydrate, placebo tablets contain 37.26 mg of anhydrous lactose per tablet. Patients with rare hereditary diseases such as galactose intolerance, lactase deficiency or glucose-galactose malabsorption who are on a lactose-free diet should not take this drug.

Women who are allergic to soy lecithin may experience allergic reactions.

The effectiveness and safety of Dimia as a contraceptive have been studied in women of reproductive age. It is assumed that in the postpubertal period up to 18 years of age, the effectiveness and safety of the drug are similar to those in women after 18 years of age. The use of the drug before menarche is not indicated.

Medical examinations

Before starting or re-using Dimia, obtain a complete medical history (including family history) and exclude pregnancy. It is necessary to measure blood pressure and conduct a medical examination, guided by contraindications and precautions. A woman should be reminded to carefully read the instructions for use and adhere to the recommendations contained therein. The frequency and content of the survey should be based on existing practice guidelines. The frequency of medical examinations is individual for each woman, but should be carried out at least once every 6 months.

Women should be reminded that oral contraceptives do not protect against HIV infection (AIDS) and other sexually transmitted diseases.

Reduced efficiency

The effectiveness of COCs may be reduced, for example, if you miss a dose of drospirenone + ethinyl estradiol tablets, have gastrointestinal disorders while taking drospirenone + ethinyl estradiol tablets, or take other medications at the same time.

Insufficient cycle control

As with other COCs, a woman may experience acyclic bleeding (spotting or withdrawal bleeding), especially in the first months of use. Therefore, any irregular bleeding should be assessed after a three-month adaptation period.

Some women do not experience withdrawal bleeding during the placebo phase. If the COC was taken in accordance with the instructions for use, then it is unlikely that the woman is pregnant. However, if the rules of administration were violated before the first missed menstrual-like withdrawal bleeding, or if two bleedings were missed, pregnancy should be excluded before continuing to take the COC.

Impact on the ability to drive vehicles and operate machinery

Not found.

Drug interactions

The effect of other drugs on the drug Dimia

Interactions between oral contraceptives and other drugs may result in acyclic bleeding and/or contraceptive failure. The interactions described below are reflected in the scientific literature.

Mechanism of interaction with hydantoin, barbiturates, primidone, carbamazepine and rifampicin; oxcarbazepine, topiramate, felbamate, ritonavir, griseofulvin and St. John's wort (Hypericum perforatum) preparations is based on the ability of these active substances to induce microsomal liver enzymes. Maximum induction of liver microsomal enzymes is not achieved within 2-3 weeks, but then persists for at least 4 weeks after cessation of drug therapy.

Contraceptive failure has also been reported with antibiotics such as ampicillin and tetracycline. The mechanism of this phenomenon is not clear.

Women during short-term treatment (up to one week) with any of the above groups of drugs or single drugs should temporarily use (while taking other drugs simultaneously and for another 7 days after its end), in addition to COCs, barrier methods of contraception.

Women receiving rifampin therapy other than COCs should use a barrier method of contraception and continue to use it for 28 days after stopping rifampin treatment. If the use of concomitant medications lasts longer than the expiration date of the active tablets in the package, the inactive tablets should be stopped and the drospirenone + ethinyl estradiol tablets from the next package should be started immediately.

If a woman is constantly taking drugs that induce microsomal liver enzymes, she should use other reliable non-hormonal methods of contraception.

The main metabolites of drospirenone in human plasma are formed without the participation of the cytochrome P450 system. Cytochrome P450 inhibitors are therefore unlikely to affect the metabolism of drospirenone.

Effect of Dimia on other drugs

Oral contraceptives may affect the metabolism of some other active ingredients. Accordingly, the concentrations of these substances in blood plasma or tissues may either increase (for example, cyclosporine) or decrease (for example, lamotrigine).

Other interactions

In patients without renal failure, concomitant use of drospirenone and ACE inhibitors or nonsteroidal anti-inflammatory drugs (NSAIDs) does not have a significant effect on serum potassium levels. However, the simultaneous use of Dimia with aldosterone antagonists or potassium-sparing diuretics has not been studied. In this case, during the first cycle of treatment, the concentration of serum potassium should be monitored.

Laboratory tests

Taking contraceptive steroids may affect the results of some laboratory tests, including biochemical parameters of liver, thyroid, adrenal and kidney function, concentrations of plasma proteins (transporters), such as corticosteroid binding proteins and lipid/lipoprotein fractions, parameters of carbohydrate metabolism and blood coagulation parameters and fibrinolysis. In general, changes remain within the normal range. Drospirenone causes an increase in renin activity in the blood plasma and, due to a slight athymineralocorticoid activity, reduces the concentration of aldosterone in the plasma.

The active substances included in this contraceptive do not have antiglucocorticoid, estrogenic, glucocorticoid abilities , as well as pronounced moderate antimineralocorticoid And antiandrogenic effect .

Its effectiveness contraceptive Dimia achieves this thanks to several factors, for example, due to inhibition of ovulation , changes endometrium and promotion secretion viscosity located in cervix .

When taken orally drospirenone almost completely and quite quickly absorbed in the stomach. The maximum concentration of the substance in the blood (Cmax) is achieved a maximum of two hours after administration contraceptive . After the distribution and metabolism stage drospirenone excreted from the body kidneys , a small part of the drug is released using intestines .

Active ingredient ethinylestradiol, included in contraceptive as well as drospirenone is rapidly absorbed and reaches its maximum concentration in the blood after two hours. The compound is excreted from the body intestines and kidneys .

Indications for use

Dimia is used as a contraceptive.

This contraceptive is contraindicated in conditions such as:

hypersensitivity to any of the active components of the drug;
venous or arterial ;
heart attack ;
cerebrovascular disorders ;
some diseases of cardio-vascular system , for example, damage heart valve or atrial fibrillation ;
stroke ;

, including suspicions against her;
period lactation ;
renal failure ;
, including benign ones;
causeless vaginal bleeding ;
lactase deficiency ;

Dimia contraceptives should be used with caution when , otorosclerosis, porphyria, chorea minor, thromboembolism, cholelithiasis, as well as for diseases that are accompanied by disorders blood circulation , For example, Crohn's disease , phlebitis , and others.

Side effects of Dimia

Side effects of Dimia may include the following ailments: genitourinary, nervous, digestive and cardiovascular systems :

vaginal bleeding spotting or breakthrough acyclic nature ;
engorgement of the mammary glands;
rare, but can develop hypertrophy mammary glands, and the composition will also change secretion vagina ;
increase or decrease libido ;
migraine ;
mood changes;
extremely rare, but may occur arterial , and ;
nausea ;
hyperkalemia ;

In addition, while taking the drug, you may experience allergic reactions and be expressed in , skin rashes, and . It is worth remembering that when using contraceptive , including the drug Dimia, body weight may increase, as well as intolerance to contact lenses, developing chloasma (hyperpigmentation) .

Dimia tablets, instructions for use (Method and dosage)

You can read about how to take the drug correctly in the instructions for Dimia. These contraceptives should be taken every day without skipping. Doctors recommend doing this at the same time, always in the order that is usually indicated on the blister. TOcontraceptives Dimia, like other similar drugs, must be used continuously for 28 days.

New packaging birth control pills Dimia should be opened only after finishing the previous one. Approximately from the third day from the start of taking the last row of tablets in the blister (placebo period), slight bleeding . If packaging contraceptive does not end by the end of the month, then the pills are started again on the first day menses .

During sexual intercourse during the first seven days of using the drug, additional methods must be used contraception (barrier). When switching to using Dimia after other complex contraception , For example, transdermal patch , tablets ,vaginal rings and so on, you should start taking this drug immediately the next day after using the previous method contraception .

When switching to Dimia after use contraceptive , which contain exclusively ( injections, implants, ) or after, you can take this drug on any convenient day. However, before you start using the tablets, you should take barrier methods of contraception.

If prescribed by a doctor, a woman can start taking these pills on the day after interruption. pregnancy (vacuum) . After childbirth It is recommended to wait 28 days and only then resume taking the drug. It is important to note that a missed dose placebo tablets (from the 4th row of the blister) is an insignificant factor.

However, this rule does not apply to tablets containing active substances. ethinyl estradiol and drospirenone . If 12 hours have not passed since the last pill was taken, the level of contraceptive protection does not decrease. The missed tablet should be taken as soon as possible, and the next one at the usual time.

You should not take a break from taking pills for more than 7 days, since this is the amount of time needed to suppress hypothalamic-pituitary ovarian system . For correct use contraceptive you should adhere to the following recommendations:

If you miss taking a pill during the first week of using the drug, a woman should resume use as soon as possible contraceptive , and also to avoid the risk of becoming pregnant, be sure to resort to additional methods barrier contraception over the next seven days;
if you miss taking the drug from 8 to 14 days of its use, you should also resume using Dimia as soon as possible, and then return to the usual schedule, and there is no need for additional contraception if the woman did not forget to take birth control pills in the previous seven days;
efficiency and reliability of this method contraception is significantly reduced if the drug is missed during the period from 15 to 24 days of its use, since at this time the woman needs to switch to placebo tablets .

To avoid unwanted pregnancy If the last of the described situations occurs when a drug is missed, the woman should take a pill to replace the missed one as quickly as possible. Next, you should stick to your usual schedule of taking the drug until the active tablets run out. As a result of mixing the dosage schedule contraceptive , designed for 28 days, will remain in the blister placebo tablets , which do not need to be taken.

Most likely, with this variant of normal withdrawal bleeding the contraceptive will not be available until the end of the next package, however, it may appear spotting . If a dose of the drug is missed between 15 and 24 days of starting its use, the woman may not return to her usual schedule of use. contraception and take 4 days (including missed days) placebo tablets , and then proceed to new packaging.

If this option does not occur withdrawal bleeding , then the possibility of pregnancy should be considered. In the presence of gastrointestinal disorder the effectiveness of the drug is reduced because the active compounds will not be completely absorbed by the stomach. If a woman vomits 4 hours after taking a contraceptive pill, she should immediately take a second one, i.e. replacement pill.

If not menstruation when taking Dimia, this may signal the onset of pregnancy . It is worth noting that A woman can correct “withdrawal” bleeding, for example, delay it on her own by changing the schedule for taking the drug.

To do this you can skip placebo tablets and immediately start taking tablets containing the active compound from the new package. It is noteworthy that when delayed or shifted withdrawal bleeding may appear acyclic lubricants or heavy bleeding .

Overdose

At the moment, there is no information about cases of overdose of Dimia. However, based on experience using complex contraceptives , similar to this drug, in case of overdose, symptoms such as nausea, vaginal bleeding, and vomit . If these symptoms occur, you should stop using the drug and consult a doctor for advice.

Interaction

To avoid weakening the effectiveness of contraceptives, you should not use Dimia together with drugs that affect liver enzymes , For example, , Primidon, Phenytoin, Oxcarbazepine, felbamate, barbiturates and others, as well as medicines containing in their chemical composition St. John's wort.

On hepatic metabolism drugs may have a negative effect HIV protease inhibitors and non-nucleoside , as well as their combinations. Demotion estrogen circulation , and therefore the effectiveness of Dimia occurs when taken simultaneously And .

For 28 and 7 days (respectively) after taking medications that affect induction of liver enzymes, and antibiotics You should stop using this drug. Contraceptives may affect the effect of some medications, so you should carefully read the instructions before using Dimia.

Terms of sale

Sold only by prescription.

Storage conditions

Contraceptives are stored out of the reach of children, at a temperature not exceeding 25 C.

Best before date

special instructions

Constant use contraception may increase the risk of developing. Moreover, this risk is highest in the first year of using a contraceptive. If the following symptoms occur while taking Dimia, you should immediately stop using the drug:

swelling of the lower extremities And strong pain ;
suddenvision loss ;
cough ;
causeless severe headache;
diplopia ;
vertigo ;
speech disorder ;
acute stomach ;
collapse ;
numbness ;
weakness ;
movement disorders .

During Dimia applications risk of dangerous thromboembolic disorders significantly occurs when:

hereditary disposition;
after the age of 30;
immobilization and after emergency surgery;
smoking;
hypertension ;
dyslipoproteinemia ;
diseases heart valves.

When using a contraceptive, be sure to consider the risk of thromboembolism especially after childbirth , as well as the development of other adverse consequences when diabetes mellitus, Crohn's disease, colitis, anemia and so on. Women should not start taking the drug without a doctor’s recommendation, as well as a preliminary medical examination.

Pharmacodynamics

Dimia ® is a combined monophasic oral contraceptive (COC) containing drospirenone and ethinyl estradiol. In terms of its pharmacological profile, drospirenone is close to natural progesterone - it does not have estrogenic, glucocorticoid and antiglucocorticoid activity and is characterized by a pronounced antiandrogenic and moderate antimineralocorticoid effect. The contraceptive effect is based on the interaction of various factors, the most important of which are inhibition of ovulation, increased viscosity of cervical secretions and changes in the endometrium. The Pearl index is an indicator reflecting the frequency of pregnancy in 100 women of reproductive age during a year of using a contraceptive - less than 1.

Pharmacokinetics

Drospirenone

Suction. When taken orally, drospirenone is quickly and almost completely absorbed from the gastrointestinal tract. Cmax of drospirenone in serum is about 38 ng/ml, achieved approximately 1-2 hours after a single dose. Bioavailability - 76-85%. Concomitant use with food does not affect the bioavailability of drospirenone.

Distribution. After oral administration, the concentration of drospirenone in the blood plasma decreases with a final half-life of 31 hours. Drospirenone binds to serum albumin and does not bind to sex hormone binding globulin (SHBG) or corticosteroid binding globulin (transcortin). Only 3-5% of total serum concentrations of drospirenone exist as free steroids. The ethinyl estradiol-induced increase in SHBG does not affect the binding of drospirenone to serum proteins. The average apparent V d of drospirenone is (3.7 ± 1.2) l/kg.

Metabolism. Drospirenone is actively metabolized after oral administration. The main metabolites in the blood plasma - the acidic forms of drospirenone, formed during the opening of the lactone ring, and 4,5-dihydro-drospirenone-3-sulfate - are formed without the participation of the P450 system. Drospirenone is metabolized to a small extent by cytochrome P450 3A4 and is capable of inhibiting this enzyme, as well as cytochromes P450 1A1, P450 2C9 and P450 2C19 in vitro.

Excretion. The renal clearance of drospirenone metabolites in blood serum is (1.5±0.2) ml/min/kg. Drospirenone is excreted only in trace amounts unchanged. Drospirenone metabolites are excreted by the kidneys and intestines with an excretion ratio of about 1.2:1.4. T1/2 of metabolites by the kidneys and through the intestines is about 40 hours.

C ss. During the treatment cycle, the maximum C ss of drospirenone in blood plasma is about 70 ng/ml, achieved after 8 days of treatment. Serum concentrations of drospirenone increase approximately 3-fold due to the ratio of final half-life and dosing interval.

Ethinyl estradiol

Suction. When taken orally, ethinyl estradiol is absorbed quickly and completely. Cmax in blood serum is about 33 pkg/ml, achieved within 1-2 hours after a single oral dose. Absolute bioavailability as a result of first pass conjugation and first pass metabolism is approximately 60%. Concomitant food intake decreased the bioavailability of ethinyl estradiol in approximately 25% of the patients studied; others had no changes.

Distribution. Serum concentrations of ethinyl estradiol decrease biphasically, in the final distribution phase T1/2 is approximately 24 hours. Ethinyl estradiol binds well, but nonspecifically, to serum albumin (approximately 98.5%) and induces an increase in serum concentrations of SHBG. Vd - about 5 l/kg.

Metabolism. Ethinyl estradiol is a substrate of presystemic conjugation in the mucous membrane of the small intestine and in the liver. Ethinyl estradiol is primarily metabolized by aromatic hydroxylation, resulting in a wide range of hydroxylated and methylated metabolites, which are present both in free form and as conjugates with glucuronic acid. Renal clearance of ethinyl estradiol metabolites is approximately 5 ml/min/kg.

Excretion. Unchanged ethinyl estradiol is practically not excreted from the body. Metabolites of ethinyl estradiol are excreted by the kidneys and through the intestines in a ratio of 4:6. T1/2 of metabolites is about 24 hours.

C ss. Occurs in the second half of the treatment cycle, and the serum concentration of ethinyl estradiol increases by 2-2.3 times.

Special patient groups

In case of impaired renal function. C ss of drospirenone in blood plasma in women with mild renal failure (Cl creatinine - 50-80 ml/min) was comparable to the corresponding indicators in women with normal renal function (Cl creatinine - > 80 ml/min). In women with moderate renal failure (Cl creatinine from 30 ml/min to 50 ml/min), the concentration of drospirenone in the blood plasma was on average 37% higher than in women with normal renal function. Drospirenone was well tolerated in all groups. Taking drospirenone did not have a clinically significant effect on serum potassium levels. Pharmacokinetics in severe renal failure have not been studied.

In case of liver dysfunction. Drospirenone is well tolerated by patients with mild to moderate hepatic impairment (Child-Pugh class B). Pharmacokinetics in severe hepatic impairment have not been studied.

Indications for Dimia ®

Oral contraception.

Contraindications

Dimia ®, like other COCs, is contraindicated in any of the following conditions:

hypersensitivity to the drug or any of the components of the drug;

thrombosis (arterial and venous) and thromboembolism currently or in history (including thrombosis, deep vein thrombophlebitis, pulmonary embolism, myocardial infarction, stroke, cerebrovascular disorders). Conditions preceding thrombosis (including transient ischemic attacks, angina pectoris), currently or in history;

multiple or severe risk factors for venous or arterial thrombosis, incl. complicated lesions of the valvular apparatus of the heart, atrial fibrillation, diseases of the cerebral vessels or coronary arteries; uncontrolled arterial hypertension, major surgery with prolonged immobilization, smoking over the age of 35 years, obesity with a body mass index >30;

hereditary or acquired predisposition to venous or arterial thrombosis, for example, resistance to activated protein C, antithrombin III deficiency, protein C deficiency, protein S deficiency, hyperhomocysteinemia and antibodies against phospholipids (presence of antibodies to phospholipids - antibodies to cardiolipin, lupus anticoagulant);

pregnancy and suspicion of it;

lactation period;

pancreatitis with severe hypertriglyceridemia currently or in history;

existing (or history of) severe liver disease, provided that liver function is not currently normalized;

severe chronic or acute renal failure;

liver tumor (benign or malignant) currently or in history;

hormone-dependent malignant neoplasms of the genital organs or breast, currently or in history;

bleeding from the vagina of unknown origin;

history of migraine with focal neurological symptoms;

lactase deficiency, lactose intolerance, glucose-galactose malabsorption, Lapp lactase deficiency.

Carefully: risk factors for the development of thrombosis and thromboembolism - smoking under the age of 35, obesity, dyslipoproteinemia, controlled arterial hypertension, migraine without focal neurological symptoms, uncomplicated valvular heart disease, hereditary predisposition to thrombosis (thrombosis, myocardial infarction or cerebrovascular accident at a young age any of the immediate relatives); diseases in which peripheral circulatory disorders may occur (diabetes mellitus without vascular complications, systemic lupus erythematosus (SLE), hemolytic-uremic syndrome, Crohn's disease, ulcerative colitis, sickle cell anemia, phlebitis of the superficial veins); hereditary angioedema; hypertriglyceridemia; severe liver disease (until normalization of liver function tests); diseases that first appeared or worsened during pregnancy or against the background of previous use of sex hormones (including jaundice and/or itching associated with cholestasis, cholelithiasis, otosclerosis with hearing impairment, porphyria, history of herpes during pregnancy, minor chorea (Sydenham's disease); chloasma; postpartum period.

Use during pregnancy and breastfeeding

Dimia ® is contraindicated during pregnancy. If pregnancy occurs while using the drug Dimia ®, its use should be stopped immediately. Extensive epidemiological studies have found neither an increased risk of birth defects in children born to women who took COCs before pregnancy, nor a teratogenic effect of COCs when taken unintentionally during pregnancy. According to preclinical studies, undesirable effects that affect the course of pregnancy and fetal development cannot be excluded due to the hormonal action of the active components. The drug Dimia ® can affect lactation: reduce the amount of milk and change its composition. Small amounts of contraceptive steroids and/or their metabolites may be excreted in milk during COC use. These amounts may affect the child. The use of Dimia ® during breastfeeding is contraindicated.

Interaction

Note: Before taking concomitant medications, you should read the drug instructions for use to identify potential interactions.

The influence of other drugs on the drug Dimia ®. Interactions between oral contraceptives and other drugs may result in acyclic bleeding and/or contraceptive failure. The interactions described below are reflected in the scientific literature.

Mechanism of interaction with hydantoin, barbiturates, primidone, carbamazepine and rifampicin; oxcarbazepine, topiramate, felbamate, ritonavir, griseofulvin and St. John's wort preparations ( Hypericum perforatum) is based on the ability of these active substances to induce microsomal liver enzymes. Maximum induction of microsomal liver enzymes is not achieved within 2-3 weeks, but then persists for at least 4 weeks after cessation of drug therapy.

Contraceptive failure has also been reported with antibiotics such as ampicillin and tetracycline. The mechanism of this phenomenon is unclear. Women during short-term treatment (up to one week) with any of the above groups of drugs or single drugs should temporarily use (during the simultaneous use of other drugs and for another 7 days after its end), in addition to COCs, barrier methods of contraception.

Women receiving rifampicin therapy other than COCs should use a barrier method of contraception and continue to use it for 28 days after stopping rifampicin treatment. If taking concomitant medications lasts longer than the expiration date of the active tablets in the package, the inactive tablets should be stopped and immediately started taking drospirenone + ethinyl estradiol tablets from the next package.

If a woman is constantly taking drugs that induce liver microsomal enzymes, she should use other reliable non-hormonal methods of contraception.

Effect of the drug Dimia ® on other drugs. Oral contraceptives may affect the metabolism of some other active ingredients. Accordingly, the concentrations of these substances in blood plasma or tissues can either increase (for example, cyclosporine) or decrease (for example, lamotrigine). Based on inhibition studies in vitro and interactions in vivo in female volunteers taking omeprazole, simvastatin and midazolam as a substrate, the effect of drospirenone at a dose of 3 mg on the metabolism of other active substances is unlikely.

Other interactions. In patients without renal failure, simultaneous use of drospirenone and ACE inhibitors or NSAIDs does not have a significant effect on serum potassium levels. However, the simultaneous use of Dimia ® with aldosterone antagonists or potassium-sparing diuretics has not been studied. In this case, during the first cycle of treatment, the concentration of serum potassium should be monitored.

Laboratory tests. Taking contraceptive steroids may affect the results of some laboratory tests, including biochemical parameters of liver, thyroid, adrenal and renal function, concentrations of plasma proteins (transporters), such as corticosteroid binding proteins and lipid/lipoprotein fractions, parameters of carbohydrate metabolism, and parameters of blood coagulation and fibrinolysis . In general, changes remain within the normal range. Drospirenone causes an increase in renin activity in the blood plasma and, due to its slight antimineralocorticoid activity, reduces the concentration of aldosterone in the plasma.

Directions for use and doses

Inside, daily, at approximately the same time, with a small amount of water, in the order indicated on the blister pack. The tablets are taken continuously for 28 days, 1 tablet. per day. Taking tablets from the next package begins after taking the last tablet from the previous package. Withdrawal bleeding usually begins 2–3 days after starting placebo tablets (last row) and does not necessarily end by the start of the next pack.

How to take Dimia ®

Hormonal contraceptives have not been used in the last month. Taking Dimia ® begins on the 1st day of the menstrual cycle (i.e., on the 1st day of menstrual bleeding). It is possible to start taking it on the 2-5th day of the menstrual cycle; in this case, additional use of a barrier method of contraception is necessary during the first 7 days of taking the tablets from the first package.

Switching from other combined contraceptives (COC tablets, vaginal ring or transdermal patch). You should start taking Dimia ® the next day after taking the last inactive tablet (for drugs containing 28 tablets) or the next day after taking the last active tablet from the previous package (possibly the next day after the end of the usual 7-day break) - for drugs containing 21 tablets. packaged. If a woman is using a vaginal ring or transdermal patch, it is preferable to start taking Dimia ® on the day of their removal or, at the latest, on the day when a new ring is planned to be inserted or the patch is replaced.

Switching from contraceptives containing only progestogens (mini-pills, injections, implants), or from an intrauterine system (IUD) that releases progestogens. A woman can switch from taking a mini-pill to taking Dimia ® on any day (from an implant or IUD - on the day of their removal, from injectable forms of drugs - on the day when the next injection was due), but in all cases it is necessary use an additional barrier method of contraception during the first 7 days of taking the pills.

After an abortion in the first trimester of pregnancy. Taking Dimia ® can be started as prescribed by a doctor on the day of termination of pregnancy. In this case, the woman does not need to take additional contraceptive measures.

After childbirth or abortion in the second trimester of pregnancy. A woman is recommended to start taking the drug on the 21-28th day after childbirth (provided that she is not breastfeeding) or abortion in the second trimester of pregnancy. If use is started later, the woman should use an additional barrier method of contraception during the first 7 days after starting to take Dimia ® . With the resumption of sexual activity (before starting to take Dimia ®), pregnancy should be excluded.

Taking missed pills

Skipping placebo tablets from the last (4th) row of the blister can be ignored. However, they should be discarded to avoid inadvertently prolonging the placebo phase. The instructions below only apply to missed tablets containing active ingredients.

If the delay exceeds 12 hours, contraceptive protection may be reduced. In this case, you can be guided by two basic rules:

1. Taking pills should never be interrupted for more than 7 days.

2. To achieve adequate suppression of the hypothalamic-pituitary-ovarian axis, 7 days of continuous pill use are required.

In accordance with this, women can be given the following recommendations:

Days 1-7. A woman should take the missed pill as soon as she remembers, even if this means taking two pills at the same time. She should then take the pills at the usual time. In addition, over the next 7 days, you should use a barrier method, such as a condom. If sexual intercourse occurred in the previous 7 days, the possibility of pregnancy should be considered. The more pills you miss and the closer this skip is to the 7-day break in taking the drug, the higher the risk of pregnancy.

Days 8-14. A woman should take the missed pill as soon as she remembers, even if this means taking two pills at the same time. She should then take the pills at the usual time. If during the 7 days preceding the first missed pill, a woman took her pills as prescribed, there is no need for additional contraceptive measures. However, if she has missed more than 1 tablet, an additional method of contraception (barrier, such as a condom) is required for 7 days.

Days 15-24. The reliability of the method inevitably decreases as the placebo pill phase approaches. However, adjusting your pill regimen can still help prevent pregnancy. When following one of the two regimens described below, and if in the previous 7 days before skipping the pill the woman complied with the drug regimen, there will be no need to use additional contraceptive measures. If this is not the case, she should follow the first of two regimens and use additional precautions for the next 7 days.

1. A woman should take the last missed pill as soon as she remembers, even if this means taking two pills at the same time. She should then take the tablets at the usual time until the active tablets are gone. You should not take 4 placebo tablets from the last row; you should immediately start taking tablets from the next blister pack. Most likely, there will be no withdrawal bleeding until the end of the second package, but spotting or withdrawal bleeding may be observed on the days of taking the drug from the second package.

If a woman misses a pill and subsequently does not experience withdrawal bleeding during the placebo pill phase, the possibility of pregnancy should be considered.

Use of the drug for gastrointestinal disorders

In case of severe gastrointestinal disorders (eg vomiting or diarrhea), absorption of the drug will be incomplete and additional contraceptive measures will be required. If vomiting occurs within 3-4 hours after taking the active tablet, you must take a new (replacement) tablet as quickly as possible. If possible, the next tablet should be taken within 12 hours of the usual tablet-taking time. If more than 12 hours have passed, it is recommended to proceed as directed when missing tablets. If a woman does not want to change her usual pill regimen, she should take an additional pill from a different pack.

Delay of menstrual withdrawal bleeding

To delay bleeding, a woman should skip taking placebo tablets from the started pack and start taking drospirenone + ethinyl estradiol tablets from a new pack. The delay can be extended until the active tablets in the second package run out. During the delay, a woman may experience acyclic heavy or spotting bleeding from the vagina. Regular use of Dimia ® is resumed after the placebo phase. To shift bleeding to another day of the week, it is recommended to shorten the upcoming phase of taking placebo tablets by the desired number of days. When the cycle is shortened, it is more likely that the woman will not have menstrual-like withdrawal bleeding, but will have acyclic heavy or spotting bleeding from the vagina when taking the next package (the same as when the cycle is lengthened).

Overdose

Cases of overdose of Dimia ® have not yet been described.

Based on general experience with COCs, potential symptoms of overdose may include: nausea, vomiting, slight bleeding from the vagina.

Treatment: there are no antidotes. Further treatment should be symptomatic.

special instructions

If any of the conditions/risk factors listed below exist, the benefits of taking COCs should be assessed individually for each woman and discussed with her before starting use. If an adverse event worsens or if any of these conditions or risk factors occur, the woman should contact her doctor. The doctor must decide whether to stop taking the COC.

Circulatory disorders

Taking any COC increases the risk of venous thromboembolism (VTE). The increase in the risk of VTE is most pronounced in the first year of a woman's use of COCs.

Epidemiological studies have shown that the incidence of VTE in women with no risk factors who took low doses of estrogens (<0,05 мг этинилэстрадиола) в составе КОК , составляет примерно 20 случаев на 100000 женщин-лет (для левоноргестрелсодержащих КОК второго поколения) или 40 случаев на 100000 женщин-лет (для дезогестрел/гестоденсодержащих КОК третьего поколения). У женщин, не пользующихся КОК , случается 5-10 ВТЭ и 60 беременностей на 100000 женщин-лет. ВТЭ фатальна в 1-2 % случаев.

Data from a large, prospective, 3-arm study showed that the incidence of VTE in women with or without other risk factors for VTE who used the combination of ethinyl estradiol and drospirenone 0.03 + 3 mg was the same as the incidence of VTE in women who used levonorgestrel-containing oral contraceptives and other COCs. The risk of VTE when taking Dimia ® has not currently been established.

Epidemiological studies have also revealed an association between COC use and an increased risk of arterial thromboembolism (myocardial infarction, transient ischemic events).

Symptoms of venous or arterial thrombotic/thromboembolic events or acute cerebrovascular accidents:

Unusual unilateral pain and/or swelling of the lower extremities;

Sudden severe chest pain, whether it radiates to the left arm or not;

Sudden shortness of breath;

Sudden onset of cough;

any unusual, severe, long-lasting headache;

Sudden partial or complete loss of vision;

Diplopia;

Impaired speech or aphasia;

Vertigo;

Collapse with or without partial epileptic seizures;

Weakness or very noticeable numbness that suddenly affects one side or part of the body;

Movement disorders;

Acute stomach.

Before starting to take COCs, a woman should consult a specialist. The risk of venous thromboembolic disorders when taking COCs increases:

With increasing age;

Hereditary predisposition (VTE has ever occurred in siblings or parents at a relatively early age);

Prolonged immobilization, extensive surgery, any surgery on the lower extremities or major trauma. In such situations, it is recommended to stop taking the drug (in case of planned surgery, at least 4 weeks in advance) and not to resume until two weeks have passed after complete restoration of mobility. If the drug is not stopped promptly, anticoagulant treatment should be considered;

There is no consensus on the possible role of varicose veins and superficial thrombophlebitis in the onset or exacerbation of venous thrombosis.

The risk of arterial thromboembolic complications or acute cerebrovascular accident increases when taking COCs:

With increasing age;

Smoking (women over 35 years of age are strongly advised to quit smoking if they wish to take COCs);

Dyslipoproteinemia;

Arterial hypertension;

Migraines without focal neurological symptoms;

Obesity (body mass index more than 30 kg/m2);

Hereditary predisposition (arterial thromboembolism ever in siblings or parents at a relatively early age). If a hereditary predisposition is possible, a woman should consult a specialist before starting to take COCs;

Damage to heart valves;

Atrial fibrillation.

The increased risk of thromboembolism in the postpartum period should be taken into account.

Other medical conditions associated with adverse vascular events include diabetes mellitus, SLE, hemolytic uremic syndrome, chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis), and sickle cell disease.

An increase in the frequency or severity of migraine while taking COCs may be an indication for their immediate discontinuation.

Tumors

The most significant risk factor for developing cervical cancer is infection with the human papillomavirus. Some epidemiological studies have reported an increased risk of cervical cancer with long-term COC use, but there remains controversy regarding the extent to which these findings are attributable to confounding factors such as cervical cancer screening or use of barrier methods of contraception.

A meta-analysis of 54 epidemiological studies found a small increase in relative risk ( relative risk - RR=1.24) development of breast cancer in women who are currently taking COCs. The risk gradually decreases over 10 years after stopping COC use. Since breast cancer rarely develops in women under 40 years of age, an increase in the number of breast cancer diagnoses in COC users has little effect on the overall likelihood of developing breast cancer. These studies did not find sufficient evidence of causality. The increased risk may be a consequence of earlier diagnosis of breast cancer in COC users, the biological effects of COCs, or a combination of both factors. Diagnosed breast cancer in women who had ever taken COCs was clinically less severe, which was due to early diagnosis of the disease.

Rarely, benign liver tumors have occurred in women taking COCs, and even more rarely, malignant liver tumors have occurred. In some cases, these tumors were life-threatening (due to intra-abdominal bleeding). This should be taken into account when making a differential diagnosis in the event of severe abdominal pain, liver enlargement, or signs of intra-abdominal bleeding.

Other

The progestogen component of the drug Dimia ® is an aldosterone antagonist that retains potassium in the body. In most cases, an increase in potassium levels is not expected. However, in a clinical study in some patients with mild to moderate kidney disease who were taking potassium-sparing medications, serum potassium levels increased slightly while taking drospirenone. Therefore, it is recommended to monitor serum potassium levels during the first cycle of treatment in patients with renal failure whose serum potassium concentration was at the ULN level before treatment, and especially when taking potassium-sparing drugs simultaneously. Women with hypertriglyceridemia or a hereditary predisposition to it may have an increased risk of pancreatitis when taking COCs. Although small increases in blood pressure were observed in many women taking COCs, clinically significant increases were rare. Only in these rare cases is it reasonable to immediately stop taking COCs. If, when taking COCs in patients with concomitant arterial hypertension, blood pressure constantly increases or significantly elevated blood pressure cannot be corrected with antihypertensive drugs, taking the COC should be discontinued. After normalization of blood pressure with the help of antihypertensive drugs, COC use can be resumed.

The following diseases appeared or worsened both during pregnancy and when taking COCs: jaundice and/or itching associated with cholestasis, gallstones; porphyria; SLE; hemolytic-uremic syndrome; rheumatic chorea (Sydenham's chorea); herpes during pregnancy; otosclerosis with hearing loss. However, evidence of their relationship with COC use is inconclusive.

In women with hereditary angioedema, exogenous estrogens may induce or worsen symptoms of edema.

Although COCs may affect peripheral insulin resistance and glucose tolerance, changing the treatment regimen in patients with diabetes mellitus while taking low-hormone COCs (containing<0,05 мг этинилэстрадиола) не показано. Однако следует внимательно наблюдать женщин с сахарным диабетом, особенно на ранних стадиях приема КОК .

While taking COCs, an increase in endogenous depression, epilepsy, Crohn's disease and ulcerative colitis was observed.

Drospirenone + ethinyl estradiol coated tablets contain 48.53 mg of lactose monohydrate, placebo tablets contain 37.26 mg of anhydrous lactose per tablet. Patients with rare hereditary diseases (such as galactose intolerance, lactase deficiency or glucose-galactose malabsorption) who are on a lactose-free diet should not take this drug.

Women who are allergic to soy lecithin may experience allergic reactions.

The effectiveness and safety of Dimia ® as a contraceptive have been studied in women of reproductive age. It is assumed that in the postpubertal period up to 18 years of age, the effectiveness and safety of the drug are similar to those in women after 18 years of age. The use of the drug before menarche is not indicated.

Medical examinations

Before starting or re-using Dimia ®, obtain a complete medical history (including family history) and exclude pregnancy. It is necessary to measure blood pressure and conduct a medical examination, guided by contraindications and precautions. A woman should be reminded to carefully read the instructions for use and adhere to the recommendations contained therein. The frequency and content of the survey should be based on existing practice guidelines. The frequency of medical examinations is individual for each woman, but should be carried out at least once every 6 months.

Women should be reminded that oral contraceptives do not protect against HIV infection (AIDS) and other sexually transmitted diseases.

Reduced efficiency

Insufficient cycle control

If acyclic bleeding recurs or begins after several regular cycles, the possibility of developing disorders of a non-hormonal nature should be taken into account and measures should be taken to exclude pregnancy or cancer, including therapeutic and diagnostic curettage of the uterine cavity. Some women do not experience withdrawal bleeding during the placebo phase. If the COC was taken in accordance with the instructions for use, then it is unlikely that the woman is pregnant. However, if the rules of dosage were violated before the first missed menstrual-like withdrawal bleeding or two bleedings were missed, pregnancy should be excluded before continuing to take the COC.

Pharmacological properties

Pharmacodynamics
The drug Dimia® is a combined hormonal contraceptive with antimineralocorticoid and antiandrogenic effects. The contraceptive effect of combined oral contraceptive drugs (COCs) is based on the interaction of various factors, the most important of which are suppression of ovulation and changes in the properties of cervical secretions, as a result of which it becomes less permeable to sperm.
When used correctly, the Pearl index (the number of pregnancies per 100 women per year) is less than 1. If you skip taking pills or use them incorrectly, the Pearl index may increase.
In women taking COCs, the menstrual cycle becomes more regular, painful menstruation is less common, and the intensity of bleeding decreases, which reduces the risk of developing anemia. In addition, according to epidemiological studies, the use of COCs reduces the risk of developing endometrial and ovarian cancer.
Drospirenone contained in Dimia® has an antimineralocorticoid effect. Prevents weight gain and the appearance of edema associated with fluid retention caused by estrogen, which ensures good tolerability of the drug. Drospirenone has a positive effect on premenstrual syndrome (PMS). The combination of drospirenone/ethinyl estradiol has been shown to be clinically effective in relieving symptoms of severe PMS, such as severe psychoemotional disturbances, breast engorgement, headache, muscle and joint pain, weight gain and other symptoms associated with the menstrual cycle. Drospirenone also has antiandrogenic activity and helps reduce the symptoms of acne (blackheads), oily skin and hair. This action of drospirenone is similar to the action of natural progesterone produced by the body.
Drospirenone does not have androgenic, estrogenic, glucocorticoid or antiglucocorticoid activity. All this, combined with antimineralocorticoid and antiandrogenic effects, provides drospirenone with a biochemical and pharmacological profile similar to natural progesterone.
When combined with ethinyl estradiol, drospirenone demonstrates a beneficial effect on the lipid profile, characterized by an increase in high-density lipoproteins.

Pharmacokinetics
Drospirenone
Suction
When taken orally, drospirenone is rapidly and almost completely absorbed from the gastrointestinal tract. The maximum concentration in blood plasma after a single oral dose is reached after approximately 1-2 hours and is about 38 ng/ml. Bioavailability 76-85%. Concomitant use with food does not affect the bioavailability of drospirenone.
Distribution
After oral administration, a biphasic decrease in the concentration of drospirenone in the blood plasma is observed, with half-lives of 1.6 ± 0.7 hours and 27.0 ± 7.5 hours, respectively. Drospirenone binds to serum albumin and does not bind to sex hormone binding globulin (SHBG). ), or with corticosteroid binding globulin. Only 3-5% of the total concentration of drospirenone in the blood plasma is present in the form of free steroids. The increase in SHBG induced by ethinyl estradiol does not affect the binding of drospirenone to plasma proteins. The average apparent volume of distribution of drospirenone is 3.7 ± 1.2 l/kg.
Metabolism
Drospirenone is actively metabolized after oral administration. Most metabolites in blood plasma are represented by acid forms of drospirenone. Drospirenone is also a substrate for oxidative metabolism catalyzed by the cytochrome P450 isoenzyme CYP3A4.
Removal
The rate of metabolic clearance of drospirenone in blood plasma is 1.5±0.2 ml/min/kg. Unmodified drospirenone is excreted only in trace amounts. Drospirenone metabolites are excreted through the intestines and kidneys in a ratio of approximately 1.2:1.4. The half-life of metabolites by the kidneys and through the intestines is about 40 hours.
Equilibrium concentration
During cyclic administration, the maximum equilibrium concentration of drospirenone in the blood plasma is achieved between the 7th and 14th day of drug administration and is approximately 70 ng/ml. Plasma concentrations of drospirenone increase approximately 2-3 times (due to accumulation), due to the relationship between the terminal half-life and the dosing interval. A further increase in the concentration of drospirenone in the blood plasma is observed between 1 and 6 cycles of administration, after which no increase in concentration is observed.
Special patient populations
Patients with renal failure
Steady-state plasma concentrations of drospirenone in women with mild renal failure (creatinine clearance (CC) 50-80 ml/min) were comparable to those in women with normal renal function (CC>80 ml/min). In women with moderate renal failure (creatinine clearance 30-50 ml/min), the plasma concentration of drospirenone was on average 37% higher than in women with normal renal function. Drospirenone treatment was well tolerated in all groups. Taking drospirenone did not have a clinically significant effect on the concentration of potassium in the blood plasma. The pharmacokinetics of drospirenone in severe renal failure have not been studied.
Patients with liver failure
Drospirenone is well tolerated in patients with mild to moderate hepatic impairment (Child-Pugh class B). Pharmacokinetics in severe hepatic impairment have not been studied.
Ethinyl estradiol

When taken orally, ethinyl estradiol is rapidly and completely absorbed. The maximum concentration in blood plasma after a single oral dose is reached after 1-2 hours and is about 88-100 pg/ml. Absolute bioavailability as a result of first-pass conjugation and first-pass metabolism is approximately 60%. Concomitant food intake reduced the bioavailability of ethinyl estradiol in approximately 25% of the patients studied, while in others such changes were not observed.
Distribution
The plasma concentration of ethinyl estradiol decreases biphasically, with a terminal phase characterized by an elimination half-life of approximately 24 hours.
Ethinyl estradiol is significantly, but nonspecifically, bound to serum albumin (approximately 98.5%) and induces an increase in plasma concentrations of SHBG. The apparent volume of distribution is about 5 l/kg.
Metabolism
Ethinyl estradiol undergoes significant first-pass metabolism in the intestine and liver. Ethinyl estradiol and its oxidized metabolites are primarily conjugated to glucuronides or sulfate. The rate of metabolic clearance of ethinyl estradiol is approximately 5 ml/min/kg.
Removal
Ethinyl estradiol is practically not excreted unchanged. Metabolites of ethinyl estradiol are excreted by the kidneys and through the intestines in a ratio of 4:6. The half-life of metabolites is about 24 hours.
Equilibrium concentration
The state of equilibrium concentration is achieved during the second half of the drug administration cycle, and the concentration of ethinyl estradiol in the blood plasma increases by approximately 1.5-2.3 times.
Preclinical safety data
Preclinical data from routine repeated dose toxicity, genotoxicity, carcinogenicity and reproductive toxicity studies do not indicate a particular risk to humans. However, it should be remembered that sex hormones can promote the growth of certain hormone-dependent tissues and tumors.

Indications for use

Contraception.
Contraception and treatment of moderate acne (acne vulgaris).
Contraception and treatment of severe premenstrual syndrome (PMS).

pregnancy or suspicion of it;
breastfeeding period;
hypersensitivity to any of the components of the drug Dimia®;
lactose intolerance, lactase deficiency, glucose-galactose malabsorption (the drug contains lactose monohydrate);
hypersensitivity to peanuts or soy.

Carefully

If any of the conditions, diseases/risk factors listed below currently exist, the potential risks and expected benefits of using COCs should be carefully weighed in each individual case:

risk factors for the development of thrombosis and thromboembolism: smoking; thrombosis, myocardial infarction or cerebrovascular accident under the age of 50 in one of the immediate family; overweight (body mass index (BMI) less than 30 kg/m2); dyslipoproteinemia; controlled arterial hypertension; migraine; uncomplicated heart valve diseases; heart rhythm disturbance;
other diseases in which peripheral circulatory disorders may occur: diabetes mellitus; systemic lupus erythematosus; hemolytic-uremic syndrome; Crohn's disease and ulcerative colitis; sickle cell anemia; as well as phlebitis of superficial veins;
hereditary angioedema;
hypertriglyceridemia;
liver diseases;
diseases that first appeared or worsened during pregnancy or against the background of previous use of sex hormones (for example, jaundice, cholestasis, cholelithiasis, otosclerosis with hearing impairment, porphyria, herpes of pregnant women, Sydenham's chorea);
postpartum period.

Use during pregnancy and breastfeeding

Pregnancy
Dimia® is contraindicated during pregnancy. If the patient is planning a pregnancy, she can stop taking Dimia® at any time. If pregnancy is detected while using Dimia®, its use should be stopped immediately. However, extensive epidemiological studies have not shown any increased risk of developmental defects in children born to women who received sex hormones (including COCs) before pregnancy, or teratogenic effects when sex hormones were taken inadvertently in early pregnancy.
Existing data on the results of taking Dimia® during pregnancy are limited, which does not allow us to draw any conclusions about the effect of the drug on the course of pregnancy, the health of the newborn and the fetus. There are currently no significant epidemiological data on Dimia®.
Breastfeeding period
The use of Dimia® during breastfeeding is contraindicated. Taking COCs can reduce the amount of breast milk and change its composition, so their use is not recommended until breastfeeding is stopped. Small amounts of sex hormones and/or their metabolites can pass into breast milk and affect the newborn's body.

Directions for use and doses

Directions for use: for oral administration.
How to take Dimia®
The tablets should be taken daily, at approximately the same time, with a small amount of water, in the order indicated on the blister pack. The tablets are taken continuously for 28 days, 1 tablet per day. Taking tablets from each subsequent package should begin the day after taking the last tablet from the previous package. Withdrawal bleeding usually begins 2-3 days after you start taking the green placebo pills (last row) and may not end before you start taking the next pack of pills. You should always start taking pills from a new pack on the same day of the week, and withdrawal bleeding will occur on approximately the same days each month.
How to start taking Dimia®

If you have not taken any hormonal contraceptives in the previous month
Taking Dimia® should be started on the first day of the menstrual cycle (i.e., on the first day of menstrual bleeding), in which case additional contraceptive measures are not required. It is possible to start taking it on days 2-5 of the menstrual cycle, but in this case it is recommended to additionally use a barrier method of contraception during the first 7 days of taking the tablets from the first package.
When switching from other combined contraceptives (COCs, vaginal ring or transdermal patch)
It is preferable to start taking Dimia® the next day after taking the last inactive tablet (for preparations containing 28 tablets per package) or the next day after taking the last active tablet from the previous package, but in no case later than the next day after the usual 7- daily break (for drugs containing 21 tablets). Taking Dimia® should be started on the day the vaginal ring or patch is removed, but no later than the day when a new ring is to be inserted or a new patch is applied.
When switching from contraceptives containing only gestagens (mini-pills, injection forms, implant), or from a gestagen-releasing intrauterine contraceptive
A woman can switch from the “mini-pill” to Dimia® any day (without a break); from an implant or intrauterine contraceptive with gestagen - on the day of its removal, from an injectable contraceptive - on the day when the next injection is due. In all cases, it is necessary to use an additional barrier method of contraception during the first 7 days of taking the pills.
After an abortion in the first trimester of pregnancy
A woman can start taking the drug immediately after a spontaneous or medical abortion in the first trimester of pregnancy. If this condition is met, the woman does not need additional contraceptive measures.
After an abortion in the second trimester of pregnancy or childbirth
Taking the drug can be started 21-28 days after a spontaneous or medical abortion or after childbirth, in the absence of breastfeeding. If use is started later, it is necessary to use an additional barrier method of contraception during the first 7 days of taking the pills. However, if sexual contact has already taken place, pregnancy should be excluded before starting to take Dimia® or you must wait until your first menstruation.

Stopping taking Dimia®
You can stop taking the drug at any time. If a woman is not planning a pregnancy, or if a woman is contraindicated for pregnancy because she is taking medications that are potentially harmful to the fetus, other methods of contraception should be discussed with the doctor.
If a woman is planning a pregnancy, it is recommended to stop taking the drug and wait for natural menstrual bleeding before trying to become pregnant. This will help you more accurately calculate your gestational age and delivery time.
Taking missed pills
Skipping a placebo tablet from the last (4th) row of the blister can be ignored.
However, they should be discarded to avoid inadvertently prolonging the placebo phase. The following recommendations apply only to skipping active tablets. If the delay in taking the drug was less than 24 hours, contraceptive protection is not reduced. The woman should take the missed pill as soon as possible and take the next pill at the usual time.
If you are late in taking your pills more than 24 hours, contraceptive protection may be reduced. The more pills you skip, and the closer the missed pills are to the inactive green placebo pill phase, the higher the chance of pregnancy.
In this case, you can be guided by the following two basic rules:

The drug should never be interrupted for more than 7 days;
To achieve adequate suppression of the hypothalamic-pituitary-ovarian axis, 7 days of continuous tablet use are required.

In accordance with this, a woman can be given the following recommendations:

If you miss pills from days 1 to 7:
A woman should take the last missed pill as soon as she remembers, even if this means taking two pills at the same time. She continues to take her next pills at the usual time. In addition, over the next 7 days it is necessary to additionally use a barrier method of contraception (for example, a condom). If sexual intercourse took place within 7 days before missing a pill, the possibility of pregnancy should be taken into account.
If you miss pills between days 8 and 14:
A woman should take the last missed pill as soon as she remembers, even if this means taking two pills at the same time. She continues to take her next pills at the usual time. If a woman has taken her pills correctly in the 7 days preceding the first missed pill, there is no need for additional contraceptive measures. Otherwise, as well as if you miss two or more tablets, you must additionally use barrier methods of contraception (for example, a condom) for 7 days.
If you miss pills between days 15 and 24:
The risk of reduced reliability is imminent due to the approaching period of taking the inactive green placebo pills. You must strictly adhere to one of the following two options. However, if during the 7 days preceding the first missed pill, all pills were taken correctly, there is no need to use additional contraceptive methods. Otherwise, the woman must use the first of the following regimens and additionally use a barrier method of contraception (for example, a condom) for 7 days.

A woman should take the last missed tablet as soon as she remembers, even if this means taking two tablets at the same time. The next tablets are taken at the usual time until the active tablets in the pack are gone, the 4 green placebo tablets from the last row should be discarded and the tablets from the next pack should be started immediately.
Withdrawal bleeding is unlikely until the second pack of tablets is gone, but spotting and/or breakthrough bleeding may occur while taking the tablets.
A woman can also stop taking active tablets from the current package. She should then take the green placebo pills from the last row for 4 days, including the days she missed pills, and then start taking the pills from the new pack.
If a woman misses taking active pills and does not experience withdrawal bleeding while taking inactive green placebo pills, pregnancy must be ruled out.

Recommendations for gastrointestinal disorders
In case of severe gastrointestinal disorders, absorption may be incomplete, so additional contraceptive measures should be taken. If you have vomiting or diarrhea within 3-4 hours after taking an active tablet, you should follow the recommendations for skipping tablets. If a woman does not want to change her usual dosing regimen and postpone the onset of menstruation to another day of the week, she should take an additional active tablet.
How to change/delay the onset of withdrawal bleeding
To delay the onset of withdrawal bleeding, a woman should continue taking tablets from the next package of Dimia®, skipping the inactive green tablets from the current package. Thus, the cycle can be extended at will for any period until the active tablets from the second package run out, that is, about 3 weeks later than usual.
If you plan to start your next cycle earlier, you must stop taking the active tablets from the second pack at any time, throw away the remaining active tablets and start taking the inactive green tablets (for a maximum of 4 days), and then start taking the tablets from the new pack. In this case, approximately 2-3 days after taking the last active tablet from the previous package, withdrawal bleeding should begin. While taking the drug from the second package, a woman may experience spotting and/or breakthrough uterine bleeding. Regular use of Dimia® is then resumed after the period of taking the inactive green tablets has ended.
To postpone the onset of withdrawal bleeding to another day of the week, a woman should reduce her next period of taking the inactive green pills by the desired number of days. The shorter the interval, the higher the risk that she will not have withdrawal bleeding and will subsequently experience spotting and/or breakthrough bleeding while taking the pills from the second package.
Use in special categories of patients
Children and teenagers
Dimia® is indicated only after menarche. Available data do not suggest dose adjustment in this group of patients.
Elderly patients
Dimia® is not indicated after menopause.
Patients with liver dysfunction
Dimia® is contraindicated in women with severe liver disease until liver function tests return to normal (see also sections “Contraindications” and “Pharmacological properties”).
Patients with impaired renal function
Dimia® is contraindicated in women with severe renal failure or acute renal failure (see also sections “Contraindications” and “Pharmacological properties”).

Side effect

The following adverse drug reactions (ADRs) were observed during use of the drospirenone/ethinyl estradiol combination.
ADRs are presented according to systemic organ classes in accordance with the MedDRA classification and with the frequency of occurrence: often (> 1/100 and<1/10), нечасто (>1/1000 and<1/100) и редко (>1/10,000 and<1/1000). В пределах каждой группы, выделенной в зависимости от частоты возникновения, НЛР представлены в порядке уменьшения их тяжести. Для дополнительных нежелательных реакций, выявленных только в процессе пострегистрационных наблюдений, и для которых оценку частоты возникновения провести не представлялось возможным, указано «частота неизвестна».

* the frequency of irregular bleeding decreases as the duration of taking Dimia® increases.

Additional Information
Listed below are adverse reactions with a very rare incidence or with delayed symptoms, which are believed to be associated with the use of drugs from the COC group (see also sections “Contraindications” and “Special instructions”).
Tumors

The incidence of breast cancer diagnosis in women taking COCs is slightly increased. Due to the fact that breast cancer is rare in women under 40 years of age, the increase in breast cancer diagnoses in women taking COCs is small relative to the overall risk of this disease.
Liver tumors (benign and malignant).

Other states

women with hypertriglyceridemia have an increased risk of pancreatitis while taking COCs;
increased blood pressure;
conditions that develop or worsen while taking COCs, but their relationship has not been proven: jaundice and/or itching associated with cholestasis; cholelithiasis; porphyria; systemic lupus erythematosus; hemolytic-uremic syndrome; chorea; herpes during pregnancy; hearing loss associated with otosclerosis;
in women with hereditary angioedema, taking estrogens may cause or aggravate its symptoms;
liver dysfunction;
changes in glucose tolerance or effects on insulin resistance;
Crohn's disease, ulcerative colitis;
chloasma;
hypersensitivity (including symptoms such as rash, urticaria).

Interaction
Interaction of COCs with other drugs (enzyme inducers) may lead to breakthrough bleeding and/or decreased contraceptive effectiveness (see section “Interaction with other drugs”).
If any of the side effects indicated in the instructions get worse or you notice any other side effects not listed in the instructions, tell your doctor.

Overdose

No serious adverse events have been reported following overdose. In preclinical studies, there were also no serious adverse effects resulting from overdose.
Symptoms which may occur in case of overdose: nausea, vomiting, spotting vaginal discharge or metrorrhagia.
Treatment. There is no specific antidote; symptomatic treatment should be carried out.

Interaction with other drugs

Effect of other drugs on Dimia®
It is possible to interact with drugs that induce microsomal enzymes, which may result in an increase in the clearance of sex hormones, which, in turn, can lead to breakthrough uterine bleeding and/or a decrease in the contraceptive effect. Women who are treated with such drugs in addition to Dimia® are recommended to use a barrier method of contraception or choose another non-hormonal method of contraception (if long-term use of inducer drugs is necessary).
A barrier method of contraception should be used during the entire period of taking concomitant medications, as well as for 28 days after their discontinuation. If the use of drugs that induce microsomal liver enzymes continues after the end of the active tablets in the Dimia® package, you should start taking Dimia® tablets from the new package without taking green placebo tablets from the old package.

Substances that increase the clearance of Dimia®(impairing effectiveness by enzyme induction): phenytoin, barbiturates, primidone, carbamazepine, rifampicin and possibly also oxcarbazepine, topiramate, felbamate, griseofulvin, as well as preparations containing St. John's wort.
Substances with different effects on the clearance of Dimia®
When used together with Dimia®, many HIV or hepatitis C virus protease inhibitors and non-nucleoside reverse transcriptase inhibitors can both increase and decrease the concentration of estrogens or progestogens in the blood plasma. In some cases, this effect may be clinically significant.
Substances that reduce the clearance of COCs (enzyme inhibitors)
Strong and moderate inhibitors of CYP3A4, such as azole antimycotics (eg, itraconazole, voriconazole, fluconazole), verapamil, macrolides (eg, clarithromycin, erythromycin), diltiazem and grapefruit juice may increase plasma concentrations of estrogen or progestogen, or both. Etoricoxib at doses of 60 and 120 mg/day, when coadministered with COCs containing 0.035 mg ethinyl estradiol, has been shown to increase plasma ethinyl estradiol concentrations by 1.4 and 1.6 times, respectively.

Effect of Dimia® on other drugs
COCs may affect the metabolism of other drugs, leading to an increase (for example, cyclosporine) or a decrease (for example, lamotrigine) in their plasma and tissue concentrations.
In vitro, drospirenone is capable of weakly or moderately inhibiting cytochrome P450 isoenzymes CYP1A1, CYP2C9, CYP2C19 and CYP3A4.
Based on in vivo interaction studies in female volunteers taking omeprazole, simvastatin or midazolam as marker substrates, it can be concluded that a clinically significant effect of 3 mg drospirenone on cytochrome P450-mediated drug metabolism is unlikely.
In vitro, ethinyl estradiol is a reversible inhibitor of the isoenzymes CYP2C19, CYP1A1 and CYP1A2, as well as an irreversible inhibitor of the isoenzymes CYP3A4/5, CYP2C8 and CYP2J2. In clinical studies, administration of a hormonal contraceptive containing ethinyl estradiol did not result in any increase or only a slight increase in plasma concentrations of CYP3A4 substrates (eg, midazolam), while plasma concentrations of CYP1A2 substrates may increase slightly (eg, theophylline) or moderate (eg, melatonin and tizanidine).
Other forms of interaction
In patients with preserved renal function, the combined use of drospirenone and angiotensin-converting enzyme inhibitors or non-steroidal anti-inflammatory drugs does not have a significant effect on the concentration of potassium in the blood plasma. However, the combined use of Dimia® with aldosterone antagonists or potassium-sparing diuretics has not been studied. In such cases, the concentration of potassium in the blood plasma must be monitored during the first cycle of taking the drug (see section "Special instructions").

special instructions

If any of the conditions, diseases/risk factors listed below currently exist, the potential risks and expected benefits of using COCs should be carefully weighed in each individual case and discussed with the woman before she decides to start taking the drug. If any of these conditions, diseases or risk factors worsen, intensify, or appear for the first time, a woman should consult her doctor, who may decide whether to discontinue the drug.
Diseases of the cardiovascular system
The results of epidemiological studies indicate a relationship between the use of COCs and an increased incidence of venous and arterial thrombosis and thromboembolism (such as deep vein thrombosis, pulmonary embolism, myocardial infarction, cerebrovascular disorders). These diseases are rare.
The risk of developing venous thromboembolism (VTE) is greatest in the first year of using such drugs. An increased risk is present after initial use of COCs or resumption of use of the same or different COCs (after a dosing interval of 4 weeks or more). Data from a prospective study involving 3 groups of patients indicate that this increased risk is predominantly present during the first 3 months of drug use. The overall risk of VTE in patients taking low-dose COCs (<0,05 мг этинилэстрадиола) в 2-3 раза выше, чем у небеременных пациенток, которые не принимают КОК, тем не менее, этот риск остается более низким по сравнению с риском ВТЭ при беременности и родах. ВТЭ может угрожать жизни или привести к летальному исходу (в 1-2% случаев).
VTE, manifested as deep vein thrombosis or pulmonary embolism, can occur with the use of any COC.
It is extremely rare when using COCs that thrombosis of other blood vessels occurs, for example, hepatic, mesenteric, renal, cerebral veins and arteries or retinal vessels. There is no consensus regarding the relationship between the occurrence of these diseases and the use of COCs.
Symptoms of deep vein thrombosis (DVT) include the following: unilateral swelling of the lower extremity or along a vein in the lower extremity, pain or discomfort in the lower extremity only when standing or walking, localized warmth in the affected lower extremity, redness or discoloration of the skin on lower limb.
Symptoms of pulmonary embolism (PE) include: difficulty or rapid breathing; sudden cough, including with hemoptysis; sharp pain in the chest, which may intensify with deep inspiration; sense of anxiety; severe dizziness; fast or irregular heartbeat. Some of these symptoms (eg, shortness of breath, cough) are nonspecific and may be misinterpreted as signs of other more or less severe conditions (eg, respiratory tract infection).
Arterial thromboembolism can lead to stroke, vascular occlusion, or myocardial infarction.
Symptoms of a stroke include: sudden weakness or loss of sensation in the face, limbs, especially on one side of the body, sudden confusion, problems with speech and understanding; sudden unilateral or bilateral vision loss; sudden disturbance in gait, dizziness, loss of balance or coordination; sudden, severe or prolonged headache for no apparent reason; loss of consciousness or fainting with or without an epileptic seizure.
Other signs of vascular occlusion: sudden pain, swelling and slight blue discoloration of the limbs, “acute” abdomen.
Symptoms of a myocardial infarction include: pain, discomfort, a feeling of pressure, heaviness, squeezing, or fullness in the chest, arm, or chest; discomfort radiating to the back, cheekbone, larynx, arm, stomach; cold sweat, nausea, vomiting or dizziness, severe weakness, anxiety or shortness of breath; fast or irregular heartbeat.
Arterial thromboembolism can be life-threatening or fatal. In women with a combination of several risk factors or high severity of one of them, the possibility of their mutual reinforcement should be considered. In such cases, the degree of increase in risk may be higher than with a simple summation of factors. In this case, taking Dimia® is contraindicated (see section “Contraindications”).
The risk of developing thrombosis (venous and/or arterial) and thromboembolism increases:

with age;
in smokers (with increasing number of cigarettes or increasing age, the risk increases, especially in women over 35 years of age);

in the presence of:

obesity (BMI more than 30 kg/m2);
family history (for example, venous or arterial thromboembolism ever in close relatives or parents under the age of 50 years). In the case of a hereditary or acquired predisposition, the woman should be examined by an appropriate specialist to decide on the possibility of taking COCs;
prolonged immobilization, major surgery, any operation on the lower limb or major trauma. In these cases, the use of Dimia® should be discontinued. In case of planned surgery, the drug should be stopped at least 4 weeks before the operation and should not be resumed for two weeks after complete restoration of motor activity. Temporary immobilization (eg, air travel lasting more than 4 hours) may also be a risk factor for the development of venous thromboembolism, especially in the presence of other risk factors;
dyslipoproteinemia;
arterial hypertension;
migraine;
heart valve diseases;
atrial fibrillation.

The use of any combined hormonal contraceptives increases the risk of developing VTE. The use of drugs containing levonorgestrel, norgestimate or norethisterone is associated with the lowest risk of developing VTE. The use of other drugs, such as Dimia®, may double the risk. The decision to use a drug other than the one with the lowest risk of developing VTE should be made only after discussion with the woman to ensure that she understands that the use of Dimia® is accompanied by the likelihood of developing VTE, and understands how her existing risk factors affect the likelihood of developing VTE, and also understands that in each first year of using the drug, her risk of developing VTE is greatest.
The possible role of varicose veins and superficial thrombophlebitis in the development of venous thromboembolism remains controversial.
The increased risk of thromboembolism in the postpartum period should be taken into account. Peripheral circulatory disorders may also occur in diabetes mellitus, systemic lupus erythematosus, hemolytic uremic syndrome, chronic inflammatory bowel disease (Crohn's disease or ulcerative colitis) and sickle cell anemia.
An increase in the frequency and severity of migraine during the use of COCs (which may precede cerebrovascular events) is grounds for immediate discontinuation of these drugs.
Biochemical indicators indicating a hereditary or acquired predisposition to venous or arterial thrombosis include the following: resistance to activated protein C, hyperhomocysteinemia, antithrombin III deficiency, protein C deficiency, protein S deficiency, antiphospholipid antibodies (anticardiolipin antibodies, lupus anticoagulant).
When assessing the risk-benefit ratio, it should be taken into account that adequate treatment of the relevant condition can reduce the associated risk of thrombosis. It should also be taken into account that the risk of thrombosis and thromboembolism during pregnancy is higher than when taking low-dose COCs (<0,05 мг этинилэстрадиола).
Tumors
The most significant risk factor for developing cervical cancer is persistent human papillomavirus infection. There are reports of a slight increase in the risk of developing cervical cancer with long-term use of COCs, but the relationship with COC use has not been proven. Controversy remains regarding the extent to which these findings are related to screening for cervical pathology or to sexual behavior (lower use of barrier methods of contraception).
A meta-analysis of 54 epidemiological studies showed that there is a slightly increased relative risk of developing breast cancer diagnosed in women currently taking COCs (relative risk 1.24). The increased risk gradually disappears within 10 years of stopping these drugs. Because breast cancer is rare in women under 40 years of age, the increase in breast cancer diagnoses in current or recent COC users is small relative to the overall risk of breast cancer. The observed increased risk may be due to earlier diagnosis of breast cancer in women using COCs, their biological effects, or a combination of both factors. Women who have used COCs are diagnosed with earlier stages of breast cancer than women who have never used them.
In rare cases, during the use of COCs, the development of benign, and in extremely rare cases, malignant liver tumors, which in some cases led to life-threatening intra-abdominal bleeding, was observed. These conditions should be taken into account when making a differential diagnosis in the event of severe abdominal pain, liver enlargement, or signs of intra-abdominal bleeding.
Tumors can be life-threatening or fatal.
Other states
Clinical studies have shown no effect of drospirenone on plasma potassium concentrations in patients with mild to moderate renal failure. There is a theoretical risk of developing hyperkalemia in patients with impaired renal function with an initial potassium concentration at the upper limit of normal, while simultaneously taking medications that lead to potassium retention in the body. In women with an increased risk of developing hyperkalemia, it is recommended to determine the concentration of potassium in the blood plasma during the first cycle of taking Dimia®.
Women with hypertriglyceridemia (or a family history of this condition) may have an increased risk of developing pancreatitis while taking COCs.
Although slight increases in blood pressure have been described in many women taking COCs, clinically significant increases have rarely been reported. However, if a persistent clinically significant increase in blood pressure develops while taking COCs, these drugs should be discontinued and treatment of arterial hypertension should be initiated. COC use can be continued if normal blood pressure values are achieved with antihypertensive therapy.
The following conditions have been reported to develop or worsen both during pregnancy and while taking COCs, but their relationship with COC use has not been proven: jaundice and/or pruritus associated with cholestasis; cholelithiasis; porphyria; systemic lupus erythematosus; hemolytic-uremic syndrome; chorea; herpes during pregnancy; hearing loss associated with otosclerosis. Cases of worsening the course of endogenous depression, epilepsy, Crohn's disease and ulcerative colitis during the use of COCs have also been described.
In women with hereditary forms of angioedema, exogenous estrogens may cause or worsen symptoms of angioedema.
Acute or chronic liver dysfunction may require discontinuation of COCs until liver function tests return to normal. Recurrent cholestatic jaundice, which develops for the first time during pregnancy or previous use of sex hormones, requires discontinuation of COC use.
Although COCs may have an effect on insulin resistance and glucose tolerance, there is no need to change the dose of hypoglycemic drugs in diabetic patients using low-dose COCs (<0,05 мг этинил-эстрадиола). Тем не менее, женщины с сахарным диабетом должны тщательно наблюдаться во время приема КОК.
Chloasma can sometimes develop, especially in women with a history of chloasma during pregnancy. Women with a tendency to chloasma should avoid prolonged exposure to the sun and exposure to ultraviolet radiation while taking COCs.
Laboratory tests
Taking COCs may affect the results of some laboratory tests, including indicators of liver, kidney, thyroid, adrenal function, the concentration of transport proteins in the blood plasma, indicators of carbohydrate metabolism, parameters of coagulation and fibrinolysis. Changes usually do not go beyond normal values. Drospirenone increases the activity of plasma renin and aldosterone, which is associated with its antimineralocorticoid effect.
Medical examinations
Before starting or resuming taking Dimia®, it is necessary to familiarize yourself with the woman’s life history, family history, conduct a thorough medical (including measuring blood pressure, heart rate, determining BMI) and gynecological examination (including examination of the mammary glands and cytological examination of scrapings from the cervix), exclude pregnancy. The scope of additional studies and the frequency of follow-up examinations are determined individually. Typically, follow-up examinations should be carried out at least once every 6 months.
The woman should be warned that COCs do not protect against HIV infection (AIDS) and other sexually transmitted diseases.
Reduced efficiency
The effectiveness of COCs may be reduced in the following cases: if active tablets are missed, with vomiting and diarrhea, or as a result of drug interactions.
Poor control of the menstrual cycle
While taking COCs, irregular bleeding may occur (“spotting” and/or “breakthrough” bleeding), especially during the first months of use. Therefore, any irregular bleeding should be assessed only after an adaptation period of approximately three cycles.
If irregular bleeding recurs or develops after previous regular cycles, a thorough diagnostic evaluation should be performed to rule out malignancy or pregnancy.
Some women may not experience withdrawal bleeding while taking green, inactive placebo pills. If the drug is taken as directed, it is unlikely that the woman is pregnant. However, if the drug has not been taken regularly before, or if there are no two withdrawal bleedings in a row, pregnancy should be ruled out before continuing to take the drug.

Soybeans
Dimia®, film-coated tablets, contains soy lecithin. Patients with peanut and soy allergies should not take this drug.
