Butagest, also known as buterol,[1] as well as 3β-hydroxy-6-methyl-17α-hydroxypregna-4,6-dien-20-one 3β-butanoate 17α-acetate or as 6-methyl-17α-hydroxy-δ6-progesterone 3β-butanoate 17α-acetate, is a steroidal progestin which was developed in Russia for potential clinical use but was never marketed.[2][3][4][5][6] It is a modification of megestrol acetate in which the C3 ketone has been replaced with a C3β butanoyloxy moiety.
