Mircette contributes to a decrease in serum concentrations of follicle-stimulating and luteinizing hormone, suppresses ovulation, increases the viscosity of the cervical secretion, disrupts the movement of sperm through the fallopian tube. It also causes endometrial restructuring, which makes it difficult for a fertilized egg to attach to the fallopian tube. Desogestrel Fast and complete absorption, bioavailability – 70%. It almost completely binds to plasma proteins. It is rapidly metabolized in the intestinal wall and in the liver to form an active metabolite (etonogestrel). The half-life is 30 hours. It is excreted by the kidneys and through the gastrointestinal tract. Ethinylestradiol It is rapidly and completely absorbed from the gastrointestinal tract. The maximum concentration in the blood serum is reached in 1-2 hours, bioavailability is 60%. It binds to plasma proteins by 97.5%. It is metabolized in the liver and intestines to etonogestrel. The half-life is 24 hours. It is eliminated by the kidneys by 45% and through the gastrointestinal tract by 30%. The half-life of metabolites is approximately 1 day.

Pregnancy and lactation
FDA category – X. If pregnancy occurs, the drug should be discontinued. The drug can affect lactation, since combined oral contraceptives reduce the amount and change the composition of breast milk. Therefore, the drug is not recommended for use until the breastfeeding mother completely stops breastfeeding. Small amounts of contraceptive steroids and/or their metabolic products may be excreted in breast milk.

Micrette birth control pills should be taken orally in the order indicated on the package, at approximately the same time every day, with a little water if necessary. Orally, 1 tablet per day from the first day of the cycle. Take the drug for 28 days without breaks.
