FLUROGESTONE (9α-FLUORO-11β,17α-DIHYDROXYPROGESTERONE) is a steroidal progestin of the 17α-hydroxyprogesterone group that was never marketed. An acetate ester, flurogestone acetate, is used in veterinary medicine. It has progestational action higher than that of progesterone itself. It is intended for intravaginal use in sheep and goats to induce oestrus synchronisation. The proposed dosage is 1 sponge, impregnated with 30, 40 (for sheep) or 45 mg (for goats) flugestone acetate, which is to be removed after 12 to 14 days from ewes and after 17 to 21 days from goats. Flugestone acetate is not indicated for use in humans.
