 Lynestrenol is used as a component of oral contraceptives in combination with an estrogen and is used in the treatment of gynecological disorders such as menstrual disorders.Lynestrenol itself does not bind to the progesterone receptor and is inactive as a progestogen.It is a prodrug, and upon oral administration, is rapidly and almost completely converted into norethisterone, a potent progestogen, in the liver during first-pass metabolism.
