Norvinisterone, sold under the brand namesNeoprogestin andNor-Progestelea, is aprogestin andandrogen/anabolic steroid (AAS) medication which was used inEurope but is now no longer marketed.[1][2][3][4][5] It is takenby mouth.
Norvinisterone is a progestin, or asyntheticprogestogen, and hence is anagonist of theprogesterone receptor, thebiological target of progestogens likeprogesterone.[2] It hasandrogenic activity.[6]
Norvinisterone wassynthesized in 1953.[2] It is no longer available.[7]
Norvinisterone was used inhormonal contraception to preventpregnancy.[1][3]
Norvinisterone is aprogestogen.[2][8][5] It appears to be quiteandrogenic, with about one-third and one-fifth of the androgenic andanabolic activity, respectively, ofnandrolone inanimalbioassays.[6] However, it has also been reported to have little anabolic activity.[9]
Norvinisterone, also known as 17α-vinyl-19-nortestosterone or as 17α-vinylestr-4-en-17β-ol-3-one, is asyntheticestranesteroid and aderivative oftestosterone and19-nortestosterone.[2]Analogues of norvinisterone include the progestinnorgesterone and the AASvinyltestosterone.[2]
Norvinisterone wassynthesized in 1953[2] and was studied in humans by 1960.[8]
Norvinisterone is thegeneric name of the drug and itsINNTooltip International Nonproprietary Name.[2] It is also known asvinylnortestosterone and is known by its developmental code nameSC-4641.[2][1]
