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