At daily reception the level of levonorgestrel increases by 3-4 times, and in the second half of a cycle equilibrium concentration is reached.

Ethinylestradiol is also well soaked up. Its maximum concentration in blood — in 1-2 hours. Its bioavailability about 45% is metabolized in a liver. For 98% communicates albumine. Decrease in concentration in blood also happens in two phases. T1/2 in the second phase — 10-20 hours. Metabolites are removed by kidneys and a liver.

About Mikroginona

On activity the combined oral contraceptives containing analogs of women's hormones which are developed in different phases of a cycle — estrogen and gestagen are considered as the most effective.

There are monophase drugs in which doses of estrogen and gestagen are constant in all tablets and throughout all cycle of their concentration in blood will be identical. Mikroginon, Femoden, Diane-35, Rigevidonum, Jeanine, Logest treats them. Also exist two - and three-phase drugs in which the content of estrogen and gestagen changes. Variable doses of hormones imitate the physiological level of hormones at a menstrual cycle.

Comments of doctors on Mikroginona are connected, first of all, with the fact that there is no best or worst drug for contraception — it is all about portability and lack of side effects. But from the point of view of physiology of the woman, three-phase the COOK which imitate the content of hormones in blood more precisely combine big efficiency and a minimum of side effects.

There are women who for years (3-8 years) accept this drug and are very happy with it as it does not cause undesirable reactions in them. And is such who could not accept it more than a month.

The main criterion of the choice of drug for protection from pregnancy is the smallest dose of steroids which is sufficient for reliable protection. The preference has to be given to drugs in which estrogen no more than 30-35 mkg, and progestins — a dose of equivalent 150 mkg of levonorgestrel. This drug meets such requirements.
