Norethisterone (or norethindrone) (or 19-nor-17-ethynyltestosterone) is a molecule used in some combined oral contraceptive pills, progestogen only pills and is also available as a standalone drug. It is a progestogen and can be used to treat premenstrual syndrome, painful periods, abnormal heavy bleeding, irregular periods, menopausal syndrome (in combination with oestrogen), or to postpone a period. It is also commonly used to help prevent uterine hemorrhage in complicated non-surgical or presurgical gynecologic cases. 
 
Norethindrone was the first orally highly active progestin to be synthesized. It was synthesized for the first time by chemists Luis Miramontes, Carl Djerassi, and George Rosenkranz at Syntex in Mexico City in 1951. I t was the progestin used in one of the first three oral contraceptives. Its related ester, norethisterone acetate, is used for the same indications Customs clearance Don't have to worry about customs pass rate,our customs clearance is 100%.
