| Lynestrenol |
Lynestrenol is an oral preparation of the synthetic progestagen, which shares various activities with the natural hormone progesterone. Lynestrenol has a strong progestational influence on the endometrium. In addition it suppresses the ovulation and menstruation for as long as the preparation is taken daily without interruption. |
|
| Norethisterone |
Norethisterone has progestational actions similar to those of progesterone, but is a more potent inhibitor of ovulation and has weak oestrogenic and androgenic properties. It is used to treat a number of disorders of the menstrual cycle. |
