Pharmaceutical properties
Medroxyprogesterone acetate is a synthetic progestogen that has a longer-lasting effect than natural progesterone. Medroxyprogesterone acetate affects the hypothalamic-pituitary system, blocking the secretion of gonadotropic hormones (FSH and LH) from the adenohypophysis. A decrease in the level of gonadotropic hormones in the blood leads to a violation of folliculogenesis in females, as a result of which follicle ovulation is inhibited and fertilization does not occur.
