개요

Norethindrone is a progestin (a synthetic substance with properties similar to progesterone) that is best known as the first female oral contraceptive, or the “pill.”Norethindrone’s global impact on society and culture has made it one of the most important inventions in history.

역사

The development of norethindrone as a female oral contraceptive took place indirectly over 30 years as a result of steroid research.This research accelerated in the 1930s when structures and medical applications of steroidal compounds were determined.Steroids are lipids, which include cholesterol, bile salts,and sex hormones,that are characterized by a structure of three fused six-carbon rings and a five-carbon ring.
In 1957, both norethindrone and norethynodrel were approved by the Food and Drug Administration (FDA) for treating menstrual problems and infertility. In 1960, the FDA approved Searle's norethynodrel under the trade name Enovid. Norethindrone was approved as an oral contraceptive in 1962 under the trade name Ortho-Novum.
