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 INNTooltip International Nonproprietary Name.^[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]
