And if this drug is taken long time a woman who already had children, then exactly the same processes take place in her reproductive system as in women who gave birth and nursed twelve children of their own. That is, this drug actually does what, in the end, nature itself would do if women dared such feats. Birth a large number children, by the way, is the most effective method prevention oncological diseases mammary glands and reproductive organs.

Pharmacology

Oral monophasic contraceptive consisting of estrogen and progestogen. The product contains artificially created gestagenic and estrogenic components, which are more effective than natural sex hormones. The effect is achieved, first of all, by blocking the production of follicle-stimulating and luteinizing hormones, which stops ovulation. This is achieved due to the increased viscosity of the cervical mucus, which prevents the entry of spermatozoa into the uterus. Regulon is a new low-dose contraceptive that contains the progestogen lll generation. Regulon does not negatively affect carbohydrate and lipid metabolism, which minimizes the harmful effect, and ensures normal tolerance with appropriate use.

Pharmacokinetics

Ethinylestradiol and desogestrel quickly and practically without residue penetrate the body through the upper sections small intestine. Ethinyl estradiol corresponds to first pass metabolism and enterohepatic circulation. Desogestrel is metabolized with the production of 3-keto-desogestrel, the remaining metabolites have no pharmacological effect. Both components have a strong (more than 90%) connection with plasma proteins. Most content in the blood is observed after 1.0-1.5 hours. Successfully spread through organs and tissues, ethinylestradiol is deposited in adipose tissue. Approximately 10% of the intake falls into breast milk. The half-life is usually 24 hours for ethinylestradiol and an average of 31 hours for desogestrel. Ethinylestradiol is eliminated by 40% by the kidneys as metabolites, by 60% by the liver.

Regulon from the Hungarian pharmaceutical company GEDEON RICHTER is a monophasic tableted contraceptive. When the first contraceptives were synthesized in the fifties of the last century, hardly anyone could have imagined that their therapeutic effect on the female body would be valued almost more than contraceptive effect. perennial clinical researches showed that patients taking the combined tablet contraceptives, much less often encountered not only gynecological, but also general somatic problems. In the course of improving the quantitative and quality composition of these drugs was found efficient mode reception, called prolonged, when the drug is taken continuously, without the traditional weekly interval. At the same time, it is possible to achieve not only the prevention of unplanned pregnancy, but also reduce the risk of developing many diseases. One drug suitable for use in this regimen is Regulon, a combination of ethinyl estradiol and desogestrel (a progestogen III generation). Even relatively a small amount desogestrel in excess is enough to suppress ovulation (60 micrograms of a substance per day suppress ovulation by 100%). Back in the late 90s of the last century, it was noted that etonogestrel, the active metabolite of desogestrel, has an extremely high affinity for progesterone receptors, has high progestogenic activity and exhibits a powerful antigonadotropic effect.

One tablet of Regulon includes 150 micrograms of desogestrel, i.e. 2.5 times more of it than is necessary to completely suppress ovulation. Another component of the contraceptive action of the drug is its ability to inhibit the formation of gonadotropins. In addition, due to the change rheological properties mucus slows down the progression of sperm through the cervical canal, and a change in the thickness and structure of the endometrium does not allow a fertilized egg to be implanted on its mucosa. The second component of the drug - ethinylestradiol - is an artificial analogue of the female sex hormone estradiol produced in the body. Regulon improves lipid profile, which manifests itself in an increase in the concentration of lipoproteins high density(“good” cholesterol) with a constant content of low-density lipoprotein (“bad” cholesterol). Taking the drug can significantly reduce blood loss during menstruation (with existing menorrhagia), improve skin condition, prevent the occurrence of acne. Before using Regulon, you must go through an in-depth medical checkup(history taking, blood pressure measurement, laboratory tests, gynecological examination). Such medical monitoring should be carried out during the period of use of the drug every six months.

Pharmacology

Monophasic oral contraceptive. The main contraceptive action is to inhibit the synthesis of gonadotropins and suppress ovulation. In addition, by increasing the viscosity of cervical mucus, the movement of spermatozoa through the cervical canal slows down, and a change in the state of the endometrium prevents the implantation of a fertilized egg.

Ethinylestradiol is a synthetic analog of endogenous estradiol.

Desogestrel has a pronounced gestagenic and antiestrogenic effect, similar to endogenous progesterone, weak androgenic and anabolic activity.

Regulon has a beneficial effect on lipid metabolism: it increases the concentration of HDL in the blood plasma, without affecting the content of LDL.

When taking the drug, the loss of menstrual blood is significantly reduced (with initial menorrhagia), the menstrual cycle is normalized, a beneficial effect on skin especially in the presence of acne vulgaris.

Pharmacokinetics

Desogestrel

Suction

Desogestrel is rapidly and almost completely absorbed from the gastrointestinal tract and is immediately metabolized to 3-keto-desogestrel, which is the biologically active metabolite of desogestrel.

C max is reached after 1.5 h and is 2 ng / ml. Bioavailability - 62-81%.

Distribution

3-keto-desogestrel binds to plasma proteins, mainly albumin and sex hormone-binding globulin (SHBG). V d is 1.5 l / kg. C ss is established by the second half of the menstrual cycle. The level of 3-keto-desogestrel increases 2-3 times.

Metabolism

In addition to 3-keto-desogestrel (which is formed in the liver and in the intestinal wall), other metabolites are formed: 3α-OH-desogestrel, 3β-OH-desogestrel, 3α-OH-5α-H-desogestrel (metabolites of the first phase). These metabolites do not have pharmacological activity and are partially, by conjugation (the second phase of metabolism), converted into polar metabolites - sulfates and glucuronates. Clearance from blood plasma is about 2 ml / min / kg of body weight.

breeding

T 1/2 3-keto-desogestrel is 30 hours. Metabolites are excreted in the urine and feces (in a ratio of 4:6).

Ethinylestradiol

Suction

Ethinylestradiol is rapidly and completely absorbed from the gastrointestinal tract. C max is achieved 1-2 hours after taking the drug and is 80 pg / ml. The bioavailability of the drug due to presystemic conjugation and the effect of "first pass" through the liver is about 60%.

Distribution

Ethinylestradiol is completely bound to plasma proteins, mainly to albumins. Vd is 5 l/kg. C ss is established by 3-4 days of administration, while the level of ethinylestradiol in serum is 30-40% higher than after a single dose of the drug.

Metabolism

Presystemic conjugation of ethinylestradiol is significant. Bypassing the intestinal wall (first phase of metabolism), it undergoes conjugation in the liver (second phase of metabolism). Ethinylestradiol and its conjugates of the first phase of metabolism (sulfates and glucuronides) are excreted into the bile and enter the enterohepatic circulation. Clearance from blood plasma is about 5 ml / min / kg of body weight.

breeding

T1 / 2 ethinylestradiol averages about 24 hours. About 40% is excreted in the urine and about 60% in the feces.

Release form

Tablets, film-coated white or almost white color, round, biconvex, marked "P8" on one side and "RG" on the other.

Excipients: α-tocopherol, magnesium stearate, colloidal silicon dioxide, stearic acid, povidone, potato starch, lactose monohydrate.

Taking the drug after childbirth

Women who are not breastfeeding can start taking pills no earlier than 21 days after giving birth, after consulting with their doctor. In this case, there is no need to use other methods of contraception. If after childbirth there was already sexual contact, then taking the pills should be postponed until the first menstruation. If a decision is made to take the drug later than 21 days after birth, then in the first 7 days it is necessary to use additional methods of contraception.

Taking the drug after an abortion

After an abortion, in the absence of contraindications, pills should be started from the first day after the operation, and in this case there is no need to use additional methods of contraception.

Switching from another oral contraceptive

If menstruation does not occur when taking the "mini-pill", then after the exclusion of pregnancy, you can start taking Regulon on any day of the cycle, but in this case, additional methods of contraception must be used in the first 7 days (use of a cervical cap with spermicidal gel, a condom, or abstinence from sexual intercourse). Application calendar method in these cases it is not recommended.

Postponement of the menstrual cycle

Treatment: in the first 2-3 hours after taking the drug in a high dose, gastric lavage is recommended. There is no specific antidote, treatment is symptomatic.

Interaction

Drugs that induce liver enzymes, such as hydantoin, barbiturates, primidone, carbamazepine, rifampicin, oxcarbazepine, topiramate, felbamate, griseofulvin, St. John's wort, reduce the effectiveness of oral contraceptives and increase the risk of breakthrough bleeding. The maximum level of induction is usually reached no earlier than 2-3 weeks, but may last up to 4 weeks after discontinuation of the drug.

Ampicillin and tetracycline reduce the effectiveness of Regulon (the mechanism of interaction has not been established). If co-administration is necessary, it is recommended to use an additional barrier method contraception throughout the course of treatment and within 7 days (for rifampicin - within 28 days) after discontinuation of the drug.

Application features

Use during pregnancy and lactation

The use of the drug during pregnancy and lactation is contraindicated.

During lactation, it is necessary to resolve the issue of either discontinuing the drug or stopping breastfeeding.

Application for violations of liver function

Contraindicated in liver failure.

With caution, the drug should be prescribed for acute and chronic liver diseases.

Application for violations of kidney function

With caution and only after a thorough assessment of the benefits and risks of use, the drug should be prescribed for kidney failure(including in history).

special instructions

Before starting the use of the drug, it is necessary to conduct a general medical (detailed family and personal history, measurement of blood pressure, laboratory tests) and gynecological examination (including examination of the mammary glands, pelvic organs, cytological analysis cervical smear). A similar examination during the period of taking the drug is carried out regularly, every 6 months.

The drug is a reliable contraceptive: the Pearl index (an indicator of the number of pregnancies that occurred during the use of a contraceptive method in 100 women for 1 year) with correct application is about 0.05.

In each case, before prescribing hormonal contraceptives, the benefits or possible negative effects their acceptance. This issue must be discussed with the patient, who, after receiving the necessary information, will make the final decision on the preference for hormonal or any other method of contraception.

The state of health of women must be carefully monitored. If any of the following conditions / diseases appear or worsen while taking the drug, you must stop taking the drug and switch to another, non-hormonal method of contraception:

  • diseases of the hemostasis system;
  • conditions/diseases predisposing to the development of cardiovascular, renal failure;
  • epilepsy;
  • migraine;
  • the risk of developing an estrogen-dependent tumor or estrogen-dependent gynecological diseases;
  • diabetes mellitus, not complicated by vascular disorders;
  • severe depression (if depression is associated with impaired tryptophan metabolism, then vitamin B 6 can be used for correction);
  • sickle cell anemia, tk. in some cases (for example, infections, hypoxia), estrogen-containing drugs in this pathology can provoke thromboembolism;
  • the appearance of abnormalities in laboratory tests for assessing liver function.

Thromboembolic diseases

Epidemiological studies have shown that there is a link between taking oral hormonal contraceptives and an increased risk of developing arterial and venous thromboembolic diseases (including myocardial infarction, stroke, deep vein thrombosis of the lower extremities, pulmonary embolism). Proved increased risk venous thromboembolic diseases, but it is much less than during pregnancy (60 cases per 100 thousand pregnancies).

Some researchers suggest that the likelihood of developing venous thromboembolic disease is greater with the use of drugs containing desogestrel and gestodene (drugs of the third generation) than with drugs containing levonorgestrel (drugs of the second generation).

The frequency of spontaneous occurrence of new cases of venous thromboembolic disease in healthy people non-pregnant women not taking oral contraceptives is about 5 cases per 100,000 women per year. When using second-generation drugs - 15 cases per 100 thousand women per year, and when using third-generation drugs - 25 cases per 100 thousand women per year.

When using oral contraceptives very rarely observed arterial or venous thromboembolism of the hepatic, mesenteric, renal vessels or retinal vessels.

The risk of developing arterial or venous thromboembolic diseases increases:

  • with age;
  • when smoking (heavy smoking and age over 35 are risk factors);
  • if there is a family history of thromboembolic diseases (for example, in parents, a brother or sister). If you suspect genetic predisposition, it is necessary to consult a specialist before using the drug;
  • with obesity (body mass index more than 30 kg / m 2);
  • with dyslipoproteinemia;
  • with arterial hypertension;
  • in diseases of the heart valves, complicated by hemodynamic disorders;
  • with atrial fibrillation;
  • with diabetes mellitus complicated by vascular lesions;
  • with prolonged immobilization, after a large surgical intervention, after surgery on the lower extremities, after a severe injury.

In these cases, a temporary cessation of the use of the drug is expected (no later than 4 weeks before surgery, and resumed no earlier than 2 weeks after remobilization).

Women after childbirth have an increased risk of venous thromboembolic disease.

It should be borne in mind that diabetes mellitus, systemic lupus erythematosus, hemolytic uremic syndrome, Crohn's disease, ulcerative colitis, sickle cell anemia, increase the risk of developing venous thromboembolic diseases.

It should be borne in mind that resistance to activated protein C, hyperhomocysteinemia, deficiency of proteins C and S, deficiency of antithrombin III, the presence of antiphospholipid antibodies increase the risk of developing arterial or venous thromboembolic diseases.

When evaluating the benefit / risk ratio of taking the drug, it should be borne in mind that targeted treatment given state reduces the risk of thromboembolism. The symptoms of thromboembolism are:

  • sudden chest pain that radiates to the left arm;
  • sudden shortness of breath;
  • any unusually severe headache that continues for a long time or appearing for the first time, especially when combined with sudden complete or partial loss of vision or diplopia, aphasia, dizziness, collapse, focal epilepsy, weakness or severe numbness of one half of the body, movement disorders, severe unilateral pain in calf muscle, sharp belly.

Tumor diseases

Some studies have reported an increase in the occurrence of cervical cancer in women who have been taking hormonal contraceptives for a long time, but the results of the studies are conflicting. play a significant role in the development of cervical cancer sexual behavior, human papillomavirus infection and other factors.

A meta-analysis of 54 epidemiological studies showed that there is a relative increase in the risk of breast cancer among women taking oral hormonal contraceptives, but higher detection of breast cancer could be associated with more regular medical examination. Breast cancer is rare among women under 40, whether they are taking hormonal birth control or not, and increases with age. Taking pills can be regarded as one of many risk factors. However, women should be advised of the potential risk of developing breast cancer based on a benefit-risk assessment (protection against ovarian and endometrial cancer).

There are few reports of the development of benign or malignant tumor liver in women taking long-term hormonal contraceptives. This should be kept in mind in the differential diagnostic evaluation of abdominal pain, which may be associated with an increase in the size of the liver or intraperitoneal bleeding.

Chloasma can develop in women who have a history of this disease during pregnancy. Those women who are at risk of developing chloasma should avoid contact with sunlight or ultraviolet radiation while taking Regulon.

Efficiency

The effectiveness of the drug may decrease in the following cases: missed pills, vomiting and diarrhea, simultaneous use of other drugs that reduce the effectiveness of birth control pills.

If the patient is simultaneously taking another drug that can reduce the effectiveness of birth control pills, additional methods of contraception should be used.

The effectiveness of the drug may be reduced if, after several months of their use, irregular, spotting or breakthrough bleeding, in such cases it is advisable to continue taking the tablets until they are finished in the next package. If, at the end of the second cycle, menstrual bleeding does not begin or acyclic spotting does not stop, stop taking the tablets and resume it only after pregnancy has been excluded.

Changes in laboratory parameters

Under the influence of oral contraceptive pills - due to the estrogen component - the level of some laboratory parameters (functional parameters of the liver, kidneys, adrenal glands, thyroid gland, hemostasis indicators, levels of lipoproteins and transport proteins) may change.

Additional Information

After an acute viral hepatitis the drug should be taken after the normalization of liver function (not earlier than after 6 months).

For diarrhea or intestinal disorders, vomiting contraceptive effect may decrease. Without stopping the drug, it is necessary to use additional non-hormonal methods contraception.

Women who smoke have an increased risk of developing vascular diseases with serious consequences (myocardial infarction, stroke). The risk depends on age (especially in women over 35) and on the number of cigarettes smoked.

A woman should be warned that the drug does not protect against HIV infection (AIDS) and other sexually transmitted diseases.

Influence on the ability to drive vehicles and control mechanisms

The drug does not affect the ability to drive a car and work with mechanisms.

Before using the drug REGULON you should consult with your doctor. These instructions for use are for informational purposes only. For more complete information please refer to the manufacturer's instructions.

Clinical and pharmacological group

23.032 (Monophasic oral contraceptive)

Release form, composition and packaging

Tablets, film-coated, white or almost white, round, biconvex, marked "P8" on one side and "RG" on the other.

Excipients: α-tocopherol, magnesium stearate, colloidal silicon dioxide, stearic acid, povidone, potato starch, lactose monohydrate.

The composition of the film shell: propylene glycol, macrogol 6000, hypromellose.

21 pcs. - blisters (1) - packs of cardboard.21 pcs. - blisters (3) - packs of cardboard.

pharmachologic effect

Monophasic oral contraceptive. The main contraceptive action is to inhibit the synthesis of gonadotropins and suppress ovulation. In addition, by increasing the viscosity of cervical mucus, the movement of spermatozoa through the cervical canal slows down, and a change in the state of the endometrium prevents the implantation of a fertilized egg.

Ethinylestradiol is a synthetic analog of endogenous estradiol.

Desogestrel has a pronounced gestagenic and antiestrogenic effect, similar to endogenous progesterone, weak androgenic and anabolic activity.

Regulon has a beneficial effect on lipid metabolism: it increases the concentration of HDL in the blood plasma, without affecting the content of LDL.

When taking the drug, the loss of menstrual blood is significantly reduced (with initial menorrhagia), the menstrual cycle is normalized, and a beneficial effect on the skin is noted, especially in the presence of acne vulgaris.

Pharmacokinetics

Desogestrel

Suction

Desogestrel is rapidly and almost completely absorbed from the gastrointestinal tract and is immediately metabolized to 3-keto-desogestrel, which is the biologically active metabolite of desogestrel.

Cmax is reached after 1.5 hours and is 2 ng / ml. Bioavailability - 62-81%.

Distribution

3-keto-desogestrel binds to plasma proteins, mainly albumin and sex hormone-binding globulin (SHBG). Vd is 1.5 l/kg. Css is established by the second half of the menstrual cycle. The level of 3-keto-desogestrel increases 2-3 times.

Metabolism

In addition to 3-keto-desogestrel (which is formed in the liver and in the intestinal wall), other metabolites are formed: 3α-OH-desogestrel, 3β-OH-desogestrel, 3α-OH-5α-H-desogestrel (metabolites of the first phase). These metabolites do not have pharmacological activity and are partially, by conjugation (the second phase of metabolism), converted into polar metabolites - sulfates and glucuronates. Clearance from blood plasma is about 2 ml / min / kg of body weight.

breeding

T1 / 2 3-keto-desogestrel is 30 hours. Metabolites are excreted in the urine and feces (in a ratio of 4:6).

Ethinylestradiol

Suction

Ethinylestradiol is rapidly and completely absorbed from the gastrointestinal tract. Cmax is achieved 1-2 hours after taking the drug and is 80 pg / ml. The bioavailability of the drug due to presystemic conjugation and the effect of "first pass" through the liver is about 60%.

Distribution

Ethinylestradiol is completely bound to plasma proteins, mainly to albumins. Vd is 5 l/kg. Css is established by 3-4 days of administration, while the level of ethinylestradiol in serum is 30-40% higher than after a single dose of the drug.

Metabolism

Presystemic conjugation of ethinylestradiol is significant. Bypassing the intestinal wall (first phase of metabolism), it undergoes conjugation in the liver (second phase of metabolism). Ethinylestradiol and its conjugates of the first phase of metabolism (sulfates and glucuronides) are excreted into the bile and enter the enterohepatic circulation. Clearance from blood plasma is about 5 ml / min / kg of body weight.

breeding

T1 / 2 ethinylestradiol averages about 24 hours. About 40% is excreted in the urine and about 60% in the feces.

REGULON: DOSAGE

The drug is prescribed inside.

Reception of tablets is begun from the 1st day of a menstrual cycle. Assign 1 tablet / day for 21 days, if possible at the same time of day. After taking the last pill from the package, a 7-day break is taken, during which menstrual-like bleeding occurs due to drug withdrawal. The next day after a 7-day break (4 weeks after taking the first tablet, on the same day of the week), the drug is resumed from the next package, also containing 21 tablets, even if the bleeding has not stopped. This scheme of taking pills is followed as long as there is a need for contraception. Subject to the rules of admission, the contraceptive effect persists for the duration of the 7-day break.

First dose of the drug

The first tablet should be taken from the first day of the menstrual cycle. In this case, you do not need to use additional methods of contraception. You can start taking pills from the 2-5th day of menstruation, but in this case, in the first cycle of using the drug, additional methods of contraception should be used in the first 7 days of taking the pills.

If more than 5 days have passed since the start of menstruation, you should postpone the start of taking the drug until the next menstruation.

Taking the drug after childbirth

Women who are not breastfeeding can start taking pills no earlier than 21 days after giving birth, after consulting with their doctor. In this case, there is no need to use other methods of contraception. If after childbirth there was already sexual contact, then taking the pills should be postponed until the first menstruation. If a decision is made to take the drug later than 21 days after birth, then in the first 7 days it is necessary to use additional methods of contraception.

Taking the drug after an abortion

After an abortion, in the absence of contraindications, pills should be started from the first day after the operation, and in this case there is no need to use additional methods of contraception.

Switching from another oral contraceptive

When switching from another oral preparation (21- or 28-day): the first tablet of Regulon is recommended to be taken the day after the completion of the course of the 28-day package of the drug. After completing the 21-day course, you must take the usual 7-day break and then start taking Regulon. There is no need to use additional methods of contraception.

Switching to Regulon after using oral progestogen-only pills ("mini-pill")

The first tablet of Regulon should be taken on the 1st day of the cycle. There is no need to use additional methods of contraception.

If menstruation does not occur when taking the “mini-pill”, then after the exclusion of pregnancy, you can start taking Regulon on any day of the cycle, but in this case, additional methods of contraception must be used in the first 7 days (use of a cervical cap with spermicidal gel, a condom, or abstinence from sexual intercourse). The use of the calendar method in these cases is not recommended.

Postponement of the menstrual cycle

If there is a need to delay menstruation, it is necessary to continue taking the tablets from the new package, without a 7-day break, according to the usual scheme. With a delay in menstruation, breakthrough or spotting bleeding may occur, but this does not reduce the contraceptive effect of the drug. Regular intake of Regulon can be restored after the usual 7-day break.

Missed pills

If a woman forgot to take a pill in a timely manner, and no more than 12 hours have passed after the missed one, you need to take the forgotten pill, and then continue taking it at the usual time. If more than 12 hours have passed between taking the pills - this is considered a missed pill, the reliability of contraception in this cycle is not guaranteed and the use of additional methods of contraception is recommended.

If you skip one tablet in the first or second week of the cycle, you need to take 2 tablets. the next day and then continue regular intake using additional methods of contraception until the end of the cycle.

If you miss a pill in the third week of the cycle, you must take the forgotten pill, continue to take it regularly and do not take a 7-day break. It is important to remember that due to the minimum dose of estrogen, the risk of ovulation and / or bleeding increases when a pill is missed, and therefore the use of additional methods of contraception is recommended.

Vomiting/diarrhea

If vomiting or diarrhea occurs after taking the drug, then the absorption of the drug may be defective. If the symptoms have stopped within 12 hours, then you need to take another tablet in addition. After that, you should continue taking the tablets in the usual way. If vomiting or diarrhea continues for more than 12 hours, then additional methods of contraception should be used during vomiting or diarrhea and for the next 7 days.

Overdose

Symptoms: nausea, vomiting, in girls - bloody discharge from the vagina.

Treatment: in the first 2-3 hours after taking the drug in a high dose, gastric lavage is recommended. There is no specific antidote, treatment is symptomatic.

drug interaction

Drugs that induce hepatic enzymes such as hydantoin, barbiturates, primidone, carbamazepine, rifampicin, topiramate, felbamate, griseofulvin, St. John's wort drugs reduce the effectiveness of oral contraceptives and increase the risk of breakthrough bleeding. The maximum level of induction is usually reached no earlier than 2-3 weeks, but may last up to 4 weeks after discontinuation of the drug.

Ampicillin and tetracycline reduce the effectiveness of Regulon (the mechanism of interaction has not been established). If co-administration is necessary, it is recommended to use an additional barrier method of contraception throughout the course of treatment and for 7 days (for rifampicin - within 28 days) after discontinuation of the drug.

Oral contraceptives may decrease carbohydrate tolerance, increase the need for insulin or oral antidiabetic agents.

Pregnancy and lactation

The use of the drug during pregnancy and lactation is contraindicated.

During the period of breastfeeding, it is necessary to resolve the issue of either discontinuing the drug or stopping it.
