Norethisterone and ethinylestradiol levels over 24 hours after a single oral dose of 10 mg NETA in postmenopausal women. [25] NETA metabolizes into ethinylestradiol at a rate of 0.20 to 0.33% across a dose range of 10 to 40 mg. [26] [27] Peak levels of ethinylestradiol with a 10, 20, or 40 mg dose of NETA were 58, 178, and 231 pg/mL, respectively.

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) [2] and of levonorgestrel acetate (levonorgestrel 17β-acetate) in ...
