Description and Uses

Medroxyprogesterone Acetate, also known as Medroxyprogesterone 17-acetate or MPA, is a synthetic progestogen and a steroidal progestin. It is derived from the human hormone progesterone. It prevents fertilization and increases the rate of transport of eggs from the fallopian tubes to the uterus in female ferrets when administered prior to ovulation. Medroxyprogesterone 17-acetate reversibly blocks ovulation in rats when injected on the last day of diestrus. It also has anti-androgenic activity in rats, decreasing plasma testosterone levels via induction of hepatic testosterone reductase activity. Medroxyprogesterone 17-acetate exhibits immunosuppressive effects in vitro and in vivo, inhibiting the production of IFN-γ by CD2/CD3/CD28-stimulated peripheral blood mononuclear cells (PBMCs) at concentrations ≥10 nM and extending the survival of rabbit skin allografts. Injectable formulations containing medroxyprogesterone 17-acetate have been used as contraceptives.

Medroxyprogesterone Acetate is a synthetic progesterone receptor agonist that is used to treat amenorrhea (unusual stopping of menstrual periods) and abnormal uterine bleeding.
