Ethisterone Descriptions:


Ethisterone was the second progestogen to be marketed (intramuscular progesterone was introduced as Proluton in 1934) and was both the first orally active progestogen and the first progestin (or synthetic progestogen) to be introduced.


Although ethisterone has largely been superseded by newer drugs and is now little used, Ethisterone continues to be available in some countries. Moreover, the 19-nortestosterone progestins, such as norethisterone, are derived from ethisterone and are widely used as hormonal contraceptives and for other indications.


Ethisterone is described as a relatively weak progestogen, similarly to its analogue dimethisterone.


Due to its androgenic activity, ethisterone has been associated with the masculinization of female fetuses in women who have taken it during pregnancy.
