Allylestrenol (BAN/INN), also known as allyloestrenol and allyl estrenol, is a synthetic progestogen used to prevent threatened miscarriage, recurrent pregnancy loss and premature labor.[1][2] In men, it has also been studied as a treatment for benign prostatic hyperplasia, with encouraging results.[3][4]

Allylestrenol is sold under several trade names, including Gestin, Turinal,Gestrenol, Gestanin, Gestanol or Gestanon, Maintaine, Orageston, and Profar. It is currently not marketed in the United States, United Kingdom, or Canada, but as of 2011, is extensively used in Bangladesh,Japan, Russia, India, and much of Southeast Asia.[1]
