pharmachologic effect

The pharmacological action is gestagenic.

Pharmacodynamics

Duphaston® (dydrogesterone) is a progestogen that is active when ingested. Dydrogesterone in its molecular structure, chemical and pharmacological properties is very close to natural progesterone. Due to the fact that dydrogesterone is not a derivative of testosterone, it does not have the side effects characteristic of most synthetic progestogens, the so-called. "Androgenic" progestogens. Dydrogesterone does not possess estrogenic, androgenic, anabolic, glucocorticoid and thermogenic activity. Acting as a progestogen component of hormone replacement therapy (HRT) in menopause, dydrogesterone helps maintain the beneficial effect of estrogens on the lipid profile of the blood. However, unlike estrogens, which usually negatively affect the blood coagulation system, dydrogesterone does not affect the coagulation indicators. Does not affect the metabolism of carbohydrates and liver function. Dydrogesterone, when administered orally, selectively affects the endometrium, thereby preventing an increased risk of endometrial hyperplasia and / or carcinogenesis in conditions of excess estrogens. It is indicated in all cases of endogenous progesterone insufficiency. The drug has no contraceptive effect. When treating dydrogesterone therapeutic effect is achieved without suppressing ovulation or menstrual dysfunction. Dydrogesterone makes it possible to conceive and maintain pregnancy during treatment.

Pharmacokinetics

After ingestion, dydrogesterone is quickly absorbed from the digestive tract (gastrointestinal tract), Cmax in the blood plasma is reached after 2 hours. Binding to plasma proteins is 97%. Metabolism in the liver occurs by hydroxylation of the ketone groups of the 20th carbon atom. Along with this, hydroxylation of methyl groups of the 21st carbon atom and in a very small volume - 16-α carbon atom was also observed. With urine output from 56 to 79%; After 24 hours, approximately 85% is output, after 72 hours the elimination process practically ends. Information on the delay or increase in the action of dydrogesterone with limited renal function has not been reported to date. Metabolites are found in the urine mainly in the form of conjugates of glucuronic acid. Presence of unchanged substance in urine was not detected.

Indications

Progesterone insufficiency: endometriosis; Infertility due to luteal insufficiency; A habitual and threatening miscarriage against the established progesterone deficiency, premenstrual syndrome, dysmenorrhea, irregular menstruation, secondary amenorrhea (in combination with estrogen therapy), dysfunctional uterine bleeding.

HRT: to neutralize the proliferative effect of estrogens on the endometrium within HRT in women with disorders due to natural or surgical menopause in the intact uterus.

Contraindications

Hypersensitivity to dydrogesterone or other components of the drug.

With caution - skin itching during the preceding pregnancy.

At present, there is no evidence of a negative effect of dydrogesterone in patients with chronic renal insufficiency.

pregnancy and lactation

The drug can be used during pregnancy (see the "Indications" box). Dydrogesterone is excreted in the mother's milk, so it is not recommended to take breastfeeding while taking the drug.

Side effects

From the hemopoietic system: in isolated cases - hemolytic anemia.

From the side of the immune system: in very rare cases - hypersensitivity reactions.

From the central nervous system (central nervous system): headache / migraine.

From the hepatobiliary system: rarely - minor violations of the liver, sometimes accompanied by weakness or malaise, jaundice and pain in the abdomen.

On the part of the reproductive system: in rare cases, the emergence of breakthrough bleeding, which can be prevented by increasing the dose of the drug; Hypersensitivity of mammary glands.

From the skin and subcutaneous tissue: rarely - skin rash, itching, urticaria; Very rarely - Quincke's edema.

General disorders: very rarely - peripheral edema.

Interaction

Inducers of microsomal liver enzymes (phenobarbital, rifampicin) can accelerate the metabolism of dydrogesterone and reduce the effect.

Dosing and Administration

Inside. Endometriosis: 10 mg 2-3 times a day from day 5 to day 25 or continuously.

Infertility (due to luteal insufficiency): 10 mg / day from the 14th to 25th day of the cycle, the course is carried out continuously for 6 consecutive cycles or more, it is recommended to continue treatment in the first months of pregnancy (as with a habitual abortion).

Threatening abortion: 40 mg once, then - 10 mg every 8 hours until the symptoms disappear.

Habitual abortion: 10 mg 2 times a day until 20 weeks of pregnancy, followed by a gradual decrease in the dose.

Premenstrual syndrome: 10 mg 2 times a day from 11 to 25 day cycle.

Dysmenorrhea: 10 mg twice daily from day 5 to day 25.

Irregular menstruation: 10 mg twice daily from 11 to 25 days of the cycle.

Amenorrhea: Estrogens - 1 time per day from 1 to 25 days, Duphaston® - 10 mg 2 times a day from 11 to 25 days of the cycle.

Dysfunctional uterine bleeding: to stop bleeding - 10 mg 2 times a day for 5-7 days; For the prevention of bleeding - 10 mg 2 times a day from 11 to 25 day cycle.

HRT in combination with estrogens: with a continuous regimen of estrogen intake - 10 mg of Dufaston ® once a day for 14 days within a 28-day cycle. In a cyclic regimen of estrogen administration: Duphaston® is 10 mg once a day for the last 12-14 days of taking estrogens. If a biopsy or ultrasound indicates insufficient reaction to a progestogen preparation, the daily dose of dydrogesterone should be increased to 20 mg.

Overdose

No symptoms of overdose have been reported. At casual reception in a dose considerably above therapeutic, gastric lavage is recommended.

Treatment: symptomatic. There is no specific antidote.

special instructions

Some patients may experience breakthrough bleeding, which is prevented by increasing the dose of the drug. In the case of the appointment of dydrogesterone in combination with estrogens (for example, for HRT), you should carefully read the contraindications and warnings associated with the use of estrogens. Before starting the combination of dydrogesterone and estrogen (for HRT) a complete history should be collected. During treatment it is recommended to periodically monitor the individual tolerability of HRT. The patient should be informed about what changes in the mammary gland she should be told to the doctor or nurse. Studies involving mammography should be conducted in accordance with the generally accepted screening of patients. In women receiving HRT, an accurate assessment of the risk and benefit is assessed over time. Sometimes breakthrough bleeding may occur during the first months of treatment. If breakthrough bleeding occurs after a certain period of taking the drug or continues after the course of treatment, the cause should be studied, an endometrial biopsy should be done to exclude malignant changes in the endometrium.

Conditions for which observation is necessary: Patients should be carefully examined for history of a progesterone-dependent tumor (eg, meningioma), and if it progresses during pregnancy or during previous hormonal therapy.

Other conditions: patients with genetically determined galactose intolerance, lactase deficiency or malabsorption syndrome should not take this medication.

The drug does not affect the ability to drive and other mechanisms.
