Medroxyprogesterone (INN BAN) also known as 17-hydroxy-6-methylprogesterone and abbreviated as MP is a steroidal progestin drug which was never marketed for use in humans. An acylated derivative medroxyprogesterone acetate (MPA) is clinically used as a pharmaceutical medicine. Compared to MPA MP is over two orders of magnitude less potent as a progestogen. As such MP itself is not used clinically though it has seen limited use in veterinary medicine under the trade name Controlestril in France. In addition it is a metabolite of MPA.
