Description
Curator's Comment: description was created based on several sources, including http://nwpeu.de/media/wysiwyg/PDFs/Femulen_PIL_.pdf

Etynodiol (used in a form of diacetate) is a steroid that was used as a contraceptive drug. Etynodiol diacetate and etynodiol are rapidly metabolized to an active metabolite, norethisterone, which binds to progesterone receptor and modulates its activity.

Originator

Searle
