GENERIC NAME: medroxyprogesterone acetate

BRAND NAME: Provera, Depo-Provera, Depo-Sub Q Provera 104

DRUG CLASS AND MECHANISM: Progestins and estrogens are the two major classes of female hormones. Medroxyprogesterone is a derivative of the naturally occurring female progestin, progesterone. Progestins are responsible for changes in the mucus and inner lining of the uterus (endometrium) during the second half (secretory phase) of the menstrual cycle. Progestins prepare the endometrium for implantation of the embryo. Once an embryo implants in the endometrium and pregnancy occurs, progestins help maintain the pregnancy. At high doses, progestins can prevent ovulation (release of the egg from the ovary) and thereby prevent pregnancy. Progestins were first isolated in 1933, and progesterone itself was synthesized in the 1940s.
