Pharmacology
Norethisterone tablet is a preparation of Norethisterone which has progestational actions similar to those of progesterone, but is a more potent inhibitor of ovulation and has weak estrogenic and androgenic properties. It is used to treat a number of disorders of the menstrual cycle. Norethisterone is absorbed from the gastrointestinal tract and its effects last for at least 24 hours. It is excreted in the urine.
