Norgestimate-d6is intended for use as an internal standard for the quantification of norgestimate by GC- or LC-MS. Norgestimate is a progestin and a prodrug form of norelgestromin and levonorgestrel .1,2It binds to progestin receptors (mean IC50= 3.48 nM for rabbit uterine receptors) and is selective for progestin over androgen receptors (mean IC50= 764 nM for rat prostatic receptors) in radioligand binding assays.3Norgestimate maintains pregnancy in ovariectomized female rats in a dose-dependent manner.1It inhibits ovulation in 100% of female rats when administered at a dose of 0.5 mg/kg. Norgestimate (2 mg/kg) completely inhibits estrone-induced vaginal cornification in ovariectomized female rats, indicating antiestrogenic activity. Formulations containing norgestimate in combination with ethinyl estradiol have been used as oral contraceptives and in the treatment of acne vulgaris.
