Ethisterone history:

 

Ethisterone was synthesized in 1938 by Hans Herloff Inhoffen, Willy Logemann, Walter Hohlweg, and Arthur Serini at Schering AG in Berlin. It was derived from testosterone via ethynylation at the C17α position, and it was hoped, that, analogously to estradiol and ethinylestradiol, ethisterone would be an orally active form of testosterone.However, the androgenic activity of ethisterone was attenuated and it showed considerable progestogenic activity.As such, it was developed as a progestogen instead and was marketed in Germany in 1939 as Proluton C and by Schering in the U.S. in 1945 as Pranone, among other brand names.

What is Ethisterone:

 

Ethisterone (brand names Pranone, Progestoral, Lutocylol, Proluton C, many others), also known as 17α-ethinyltestosterone, pregneninolone, or anhydrohydroxyprogesterone, is asteroidal progestin with androgenic activity which is derived from testosterone and was introduced for medical use in 1939. It 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progestogen and the first progestin (orsynthetic progestogen) to be introduced.Although ethisterone has largely been superseded by newer drugs and is now little used, it continues to be available in some countries.Moreover, the 19-nortestosterone progestins, such as norethisterone, are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 ashormonal contraceptives and for other indications.

 

Ethisterone Application:

 

The first orally active progestin, ethisterone (pregneninolone, 17α -ethynyltestosterone or 19-norandrostane), the 17α -ethynyl analog of testosterone, was synthesized in 1938 by Hans Herloff Inhoffen, Willy Logemann, Walter Hohlweg, and Arthur Serini at Schering AG in Berlin and marketed in Germany in 1939 as Proluton C and by Schering in the U. S. In 1945 as Pranone.
Ethisterone was also marketed in the U. S. From the 1950s into the 1960s under a variety of trade names by other pharmaceutical companies that had been members of the pre-World War II European hormone cartel (Ciba, Organon, Roussel).

This product is also easily absorbed from the oral mucosa, so sublingual use it effectively.
Also used to prevent threatened abortion and habitual abortion, but because of the maintenance of pregnancy are less effective, the effect is not good, such as the estrogen ethinyl estradiol combination is good effect.
