Ethisterone (INN, USAN, BAN) (brand names Pranone, Progestoral, Lutocylol, Proluton C, many others), also known as17α-ethinyltestosterone, pregneninolone, or anhydrohydroxyprogesterone, is a steroidal progestin with androgenicactivity which is derived from testosterone and was introduced for medical use in 1939.It was the secondprogestogen to be marketed (intramuscular progesterone was introduced as Proluton in 1934) and was both the firstorally 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progestogen and the first progestin (or synthetic progestogen) to be introduced.Although ethisterone has largely been superseded by newer drugs and is now little used, it continues to be available in some countries.Moreover, the 19-nortestosterone progestins, such as norethisterone, are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.
