Medroxyprogesterone is a synthetic progestin, a derivative of progesterone, used primarily for hormone replacement therapy, treatment of endometriosis, dysmenorrhea, and as a component of some contraceptive formulations. It is available in both oral and injectable forms. Medroxyprogesterone acetate (MPA) is the main clinically used form. This drug is approved and in current therapeutic use.
