Chlormethenmadinone acetate (CMMA), also known as chlorsuperlutin, is a progestin medication which was developed in Czechoslovakia in the 1960s.[1] It has been used in combination with mestranol in birth control pills under the brand names Biogest, Sterolibrin, and Antigest B,[2][3] and in veterinary medicine under the brand name Agelin.[4] Analogues of CMMA include bromethenmadinone acetate (bromsuperlutin), which was assessed but was never marketed,[3][5] and melengestrol acetate (methylsuperlutin), which is used in veterinary medicine.[6]
