Megestrol acetate (INN USAN BAN JAN; sold mainly under the brand names Megace and Megace ES) also known as 17α-acetoxy-6-dehydro-6-methylprogesterone and sometimes abbreviated as MGA or MA is a steroidal progestin and progesterone derivative (specifically a 17-hydroxylated progesterone) with predominantly progestational and antigonadotropic effects.Though sometimes referred to simply as megestrol it is important to clarify that megestrol acetate is not the same as megestrol which is a closely related but different compound.
