Norvinisterone, sold under the brand names Neoprogestin and Nor-Progestelea, is a progestin and androgen/anabolic steroid (AAS) medication which was used in Europe but is now no longer marketed.[1][2][3][4][5] It is taken by mouth.

Norvinisterone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[2] It has androgenic activity.[6]

Norvinisterone was synthesized in 1953.[2] It is no longer available.[7]

Medical uses

Norvinisterone was used in hormonal contraception to prevent pregnancy.[1][3]

Pharmacology

Pharmacodynamics

Norvinisterone is a progestogen.[2][8][5] It appears to be quite androgenic, with about one-third and one-fifth of the androgenic and anabolic activity, respectively, of nandrolone in animal bioassays.[6] However, it has also been reported to have little anabolic activity.[9]

Chemistry

Norvinisterone, also known as 17α-vinyl-19-nortestosterone or as 17α-vinylestr-4-en-17β-ol-3-one, is a synthetic estrane steroid and a derivative of testosterone and 19-nortestosterone.[2] Analogues of norvinisterone include the progestin norgesterone and the AAS vinyltestosterone.[2]

History

Norvinisterone was synthesized in 1953[2] and was studied in humans by 1960.[8]

Society and culture

Generic names

Norvinisterone is the generic name of the drug and its INN.[2] It is also known as vinylnortestosterone and is known by its developmental code name SC-4641.[2][1]

Brand names

Norvinisterone was marketed under the brand names Neoprogestin and Nor-Progestelea by Syntex.[2][1]

Availability

Norgesterone is no longer marketed and hence is no longer available in any country.[7]
