About this molecule
Norethisterone, also known as norethindrone, is a synthetic progestational hormone belonging to the 19-nortestosterone-derived class of progestins. It is further classified as a second-generation progestin, along with [levonorgestrel] and its derivatives, and is the active form of several other progestins including [norethynodrel] and [lynestrenol]. Norethisterone mimics the actions of endogenous [progesterone], albeit with a greater potency, and is used on its own or in combination with estrogen derivatives in a variety of applications including contraception and hormone replacement therapy. First derived in 1951 in Mexico City, norethisterone was originally intended for use as a remedy for irregular menstruation and endometriosis, and was not marketed for use as an oral contraceptive until 1962.
