Norgesterone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[7] It has no androgenic activity.[7]
Norgesterone was first described in 1962.[8][9] It is no longer available.[10]
Medical uses
editNorgesterone was used in combination with ethinylestradiol in birth control pills to prevent pregnancy.[2] It is no longer available.[10]
Pharmacology
editPharmacodynamics
editNorgesterone is a progestogen, and hence is an agonist of the progesterone receptor.[7] Unlike related progestins, it is virtually devoid of androgenic activity in animal assays.[7]
Chemistry
editNorgesterone, also known as 17α-vinyl-δ5(10)-19-nortestosterone or as 17α-vinylestr-5(10)-en-17β-ol-3-one, is a synthetic estrane steroid and a derivative of testosterone and 19-nortestosterone.[1] Analogues of norgesterone include norvinisterone (17α-vinyl-19-nortestosterone) and vinyltestosterone (17α-vinyltestosterone).[1]
History
editSociety and culture
editGeneric names
editNorgesterone is the generic name of the drug and its INN.[1] It has also been referred to as norvinodrel, vinylestrenolone, and vinylnoretynodrel.[1][11]
Brand names
editNorgesterone was marketed in combination with ethinylestradiol, an estrogen, as a birth control pill under the brand name Vestalin.[2][3][4]
Availability
editNorgesterone is no longer marketed and hence is no longer available in any country.[10]
