Pharmacodynamics and pharmacokinetics

Pharmacodynamics

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 womans 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.

Pharmacokinetics

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.

Indications for use
