Norgestimate

Ethinylestradiol/norgestimatePrefest
Norgestimate is the C3 oxime of LNG-A.
Norgestimate is a rapidly and completely converted prodrug, mainly of norelgestromin (17β-deacetylnorgestimate or levonorgestrel 3-oxime), but also of levonorgestrel (3-keto-17β-deacetylnorgestimate) to a lesser extent (22 ± 6% of an administered dose or about 40–70 µg) and of levonorgestrel acetate (levonorgestrel 17β-acetate) in very small amounts.
