Medroxyprogesterone caproate (MPC) is a progestin and a progestogen ester which was synthesized in 1958 but was never marketed.[1][2] It has been confused with hydroxyprogesterone caproate (OHPC) and medroxyprogesterone acetate (MPA) in a number of publications.[3][4][5][6][7][8][9][10][11][12] In addition to MPA and OHPC, analogues of MPC include chlormadinone caproate, gestonorone caproate, megestrol caproate, and methenmadinone caproate.
