产品描述：一种合成的孕激素类似物，一种具有口服活性，高度选择性的孕激素活性和最小雄激素作用的孕激素 (progestin)。Norgestimate 可用于口服避孕药。Norgestimate is an acetylated progestinused in combination with ethinyl estradiol as an oral contraceptive. It acts as a prodrug to norelgestromin (17-deacetylnorgestimate or levonorgestrel 3-oxime), the primary active metabolite, and levonorgestrel (deacetylation of norgestimate occurs in the intestines and the liver). Unlike levonorgestrel, norgestimate shows high selectivity for the progesterone receptor and low androgenic action due to a large drug-induced elevation in the level of sex hormone-binding globulin (SHBG) (which preferentially binds androgens and thus inhibits their action). In accordance, clinical trials have observed minimal androgenic side effects. Norgestimate and its metabolites themselves, unlike many other progestins, do not bind to SHBG.
