Mechanism of action

Anti-estrogen drug nonsteroidal structure. The mechanism of action is explained by the ability to specifically bind to estrogen receptors in the hypothalamus and ovaries. In small doses, the drug enhances the secretion of gonadotropic hormones (prolactin, follicle-stimulating and luteinizing hormones) and stimulates ovulation. Reducing the level of circulating estrogens (which inhibit the secretion of gonadotropic hormones in high concentrations), increases the secretion of gonadotropins.

After taking the drug inside clomiphene is well absorbed from the gastrointestinal tract.
Due to the strong binding to plasma proteins, the drug is slowly excreted from the plasma. Clomiphene and its metabolites undergo enterohepatic recirculation and accumulate in adipose tissue.
Clomiphene is metabolized to form metabolites with anti-estrogenic activity.
T1/2 Clomiphene is 5-7 days.
It is excreted unchanged and in the form of metabolites, mainly with feces (37-51%), usually within 3 weeks.

If this is not enough to induce ovulation, the same course (100 mg for 5 days) can be repeated in the next cycle.In case of continuing anovulation, after a 3-month break, 3 courses of treatment can be additionally performed in the same doses.
