A progestin is a synthetic progestagen that has progestinic effects similar to progesterone. The two most frequent uses of progestins are for hormonal contraception (either alone or with an estrogen), and to prevent endometrial hyperplasia from unopposed estrogen in hormone replacement therapy. Progestins are also used to treat secondary amenorrhea, dysfunctional uterine bleeding and endometriosis,
and as palliative treatment of endometrial cancer, renal cell carcinoma, breast cancer, and prostate cancer. High dose megestrol acetate is used to treat anorexia, cachexia and AIDS-related wasting.
Progesterone (or sometimes the progestin dydrogesterone or 17α-hydroxyprogesterone caproate) is used for luteal support in IVF protocols, questionably for treatment of
recurrent pregnancy loss, and for prevention of preterm birth in pregnant women with a history of at least one spontaneous preterm birth."Loose 2006">
History
The recognition of progesterones ability to suppress ovulation during pregnancy spawned a search for a similar hormone that could bypass the problems associated with administering progesterone (low bioavailability when administered orally and local irritation and pain when continually administered parenterally) and, at the same time, serve the purpose of controlling ovulation. The many synthetic hormones that resulted are known as progestins.
The first orally active progestin, ethisterone (pregneninolone, 17α-ethynyltestosterone), the 17α-ethynyl analog of testosterone, synthesized in 1938 by Hans Herloff Inhoffen, Willy Logemann, Walter Hohlweg and Arthur Serini at Schering AG in Berlin, was marketed in Germany in 1939 as Proluton C and by Schering in the U.S. in 1945 as Pranone"Inhoffen 1938">"Maisel 1965">"Petrow 1970">"Sneader 2005">"Djerassi 2006">
A more potent orally active progestin, norethisterone (norethindrone, 19-nor-17α-ethynyltestosterone), the 19-nor analog of ethisterone, synthesized in 1951 by Carl Djera read more at » http://en.wikipedia.org/wiki/Progestin
