Megestrol (Meg)
Megestrol is a steroidal progestin which was never marketed. Its acylated derivative megestrol acetate is also a progestogen, which, in contrast to megestrol itself, has been extensively used as a pharmaceutical drug. Megestrol acetate is used mainly as an appetite stimulant in a variety of conditions and as an antineoplastic agent in the treatment of breast, endometrial, and prostate cancers. When given in relatively high doses, it can substantially increase appetite in most individuals, even those with advanced cancer, and is often used to boost appetite and induce weight gain in patients with cancer or HIV/AIDS-associated cachexia. It is also used as a contraceptive in combination with an estrogen at relatively low doses. In addition to its use in humans, megestrol acetate has been used extensively in veterinary medicine in the treatment of medical conditions in cats and dogs.
