medroxyprogesterone acetate – 50 mg;
Excipients: methyl parahydroxybenzoate, propyl parahydroxybenzoate, sodium chloride, polysorbate 80, polyethylene oxide 1500, water for injections.
Pharmacological properties:
Medroxyprogesterone acetate is a synthetic progestogen that has a longer duration of action than natural progesterone. Medroxyprogesterone acetate affects the hypothalamic-pituitary system by blocking the secretion of gonadotropic hormones (FSH and LH) from the adenohypophysis. Decreased levels of gonadotropic hormones in the blood leads to impaired folliculogenesis in females, resulting in inhibited ovulation of follicles and no fertilization.
