Pharmacodynamics and pharmacokinetics
Combined preparation for contraception, taken orally.
Prolonged use of the drug leads to a decrease in the secretion of follicle-stimulating hormone and lyutenizing hormone, and, consequently, to suppression of the ovulation process. Simultaneously, there is proliferation and secretory transformation of the endometrium, preventing the fixation of a fertilized egg. The viscosity of mucous secretions from the cervix increases, which passes with difficulty of passage of male sex cells through the cervical canal and inhibition of their mobility.
The chloromadinone acetate that enters the drug is a gestagen that has antiandrogenic properties. Its effect is based on the ability to compete with androgens in specific receptors, weakening the effect of androgens. The Perl index (the probability of getting pregnant within 12 months) varies between 0.291-0.698 and depends on the thoroughness of the woman's adherence to the regimen.
To completely block ovulation, approximately 1.7 mg of chloromadinone acetate is required daily. The required dosage per cycle is 25 mg.
Chlormadinone acetate. Quickly and completely absorbed. The maximum concentration occurs an hour and a half. 95% binds to human blood proteins, mainly albumin.
In the process of transformation, many metabolites are formed, the main ones being 3-beta and 3-alpha-hydroxy-chloromadinone acetate.
The average half-life of blood is 34 hours. Chlormadinone acetate and its metabolites are excreted in approximately equal amounts with urine and through the intestine.
Ethinyl estradiol. Quickly and almost completely absorbed from the intestine, reaching a maximum concentration in the plasma in an hour and a half. Absolute bioavailability is about 40%.
About 98% of the substance binds to blood proteins. Ethinyl estradiol is transformed by hydroxylation of the aromatic ring. The main derivative is 2-hydroxy-ethynylestradiol.
The average half-life of ethinylestradiol from the blood is 13 hours. It is excreted by the kidneys and with feces in the proportion of 2: 3.

Tablets should be consumed every day at the same time (preferably in the evening) for 21 consecutive days, then you should stop taking the medication for 7 days; approximately 2-4 days after the use of the last pill develop bleeding cancellation, similar to menstrual.
After completing the 7-day break, you need to start using the drug from the next pack, regardless of whether the bleeding has stopped.
The first pill must necessarily drink on the first day of the physiological cycle of a woman (the first day of the next menstruation). In this case, the contraceptive effect begins with the first day of admission and lasts for a one-week break in admission.
The first tablet can be drunk on the 1-5th day of menstrual bleeding (it does not matter if the bleeding has stopped or not). In this case, during the first seven days of admission, barrier methods of contraception must also be used.

Bleeding cancellation usually does not occur until all the tablets in the second package are used, but exceptions are possible. If withdrawal bleeding does not appear after the end of the second package, you need to perform a pregnancy test.

The following substances can reduce the concentration of ethinyl estradiol in the blood and weaken contraceptive activity:
all drugs that increase intestinal motility or inhibit absorption;
substances that activate microsomal hepatic enzymes, such as Rifabutin, Rifampicin, barbiturates, Griseofulvin, anticonvulsants, Barbexaclone, Modafinil, protease inhibitors, Primidon, St. John's Wort preparations;
a number of antibiotics (for example, tetracycline, Ampicillin).
With the simultaneous use of such drugs, it is necessary to apply additional barrier methods of contraception during therapy and within a week after it. When taking substances that lower the concentration of ethinyl estradiol in the blood by activating microsomal liver enzymes, additional barrier methods should be used within four weeks after the end of therapy.
The following substances may increase the concentration of ethinylestradiol in the blood:
substances that inhibit the sulfation of ethinyl estradiol in the intestine (ascorbic acid, paracetamol);
substances that block the activity of microsomal liver enzymes (antifungal imidazoles, indinavir, trolleandomycin);
Keep away from children and store at temperatures up to 25 degrees.
