Methenmadinone acetate
Methenmadinone acetate, also known as methylenedehydroacetoxyprogesterone and sold under the brand names Superlutin and Antigest, is a progestin medication which was developed in Czechoslovakia in the 1960s. It is the C17α acetate ester of methenmadinone.
MMA given orally shows about 13-fold the progestogenic activity of parenteral progesterone in animal bioassays.
Analogues of methenmadinone acetate include methenmadinone caproate, which was studied in combination with estradiol valerate as a combined injectable contraceptive ; chlormethenmadinone acetate, which has been used in combination with mestranol in birth control pills and in veterinary medicine ; bromethenmadinone acetate, which was assessed but was never marketed; and melengestrol acetate, which is used in veterinary medicine.
