Pharmacodynamics of Allylestrenol

Allylestrenol is sold under several trade names, including Gestin, Turinal, 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 Japan, Russia, India, and much of Southeast Asia.
Allylestrenol is used for miscarriage prevention, prevention of premature labour and has been investigated for possible use in men for treatment for benign prostatic hyperplasia.
Allylestrenol is a progestogen structurally related to progesterone that has been given in threatened and recurrent miscarriage, and to prevent premature labour. However, with the exception of proven progesterone deficiency, such use is no longer recommended. In threatened miscarriage in progesterone-deficient women a suggested dose is 5 mg three times daily by mouth for 5 to 7 days.
