Chlormadinone caproate (CMC) is a progestin and a progestogen ester which was studied for potential use in combined injectable contraceptives but was never marketed.[1][2][3][4] It was assessed in combination with estradiol valerate at doses of 80 mg and 3 mg, respectively.[1][2][3] In addition to chlormadinone acetate (CMA), analogues of CMC include gestonorone caproate, hydroxyprogesterone caproate, medroxyprogesterone caproate, megestrol caproate, and methenmadinone caproate.[5]
