Medroxyprogesterone (MP), is a progestin which is not used medically. A derivative, medroxyprogesterone acetate (MPA), is used as a medication in humans, and is far more widely known in comparison. Medroxyprogesterone is sometimes used as a synonym for medroxyprogesterone acetate,
Pharmacology
Pharmacodynamics
Compared to MPA, medroxyprogesterone is over two orders of magnitude less potent as a progestogen. Medroxyprogesterone is also notable in that it is a minor metabolite of MPA. In addition to its progestagenic activity, medroxyprogesterone is a weak antiandrogen in vitro on human androgen receptor.

Chemistry
Medroxyprogesterone, also known as 6α-methyl-17α-hydroxyprogesterone or as 6α-methyl-17α-hydroxypregn-4-en-3,20-dione, is a synthetic pregnane steroid and a derivative of progesterone. It is specifically a derivative of 17α-hydroxyprogesterone with a methyl group at the C6α position. The generic name of medroxyprogesterone is a contraction of 6α-methyl-17α-hydroxyprogesterone. It is closely related to medrogestone as well as other unesterified 17α-hydroxyprogesterone derivatives such as chlormadinone, cyproterone, and megestrol.
