Mode of action:
Novinet is an oral contraceptive. In its composition contains a synthetic estrogen ethinyl estradiol (EE) and the progestogen desogestrel. Desogestrel, like all synthetic progestogens have a high affinity for the progesterone receptors, located in the area of the hypothalamic-gipofizirnoy. Consequently, it is able to induce low dose effect of negative feedback. The result is a dramatic reduction in blocking the release of gonadotropins and ovulation. The value of a daily dose of the estrogen component is 20 micrograms can be attributed to Novinet mikrodozirovannym contraceptives. Progestogen and estrogen dose remains unchanged in all tablets per administration cycle. These drugs are called monophasic.
