Anagestone acetate

Anagestone acetate (USAN) (brand name Anatropin; former developmental code name ORF-1658), also known as 17α-hydroxy-6α-methylpregn-4-en-20-one acetate, is a steroidal progestin that was formerly marketed by Ortho Pharmaceutical. Under the brand name Neo-Novum and in combination with the estrogen mestranol, it was introduced in 1968 as an oral contraceptive in the United States. Anagestone acetate is the acetate ester of anagestone, which, in contrast to anagestone acetate, was never marketed.
