Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination estrogen-progestin contraceptive; suppresses gonadotropin (FSH, LH) release, inhibiting ovulation, altering cervical mucus, and reducing endometrial receptivity.
Combination oral contraceptive containing ethinyl estradiol and desogestrel. Ethinyl estradiol suppresses gonadotropin release via negative feedback on the hypothalamic-pituitary axis; desogestrel, a progestin, inhibits ovulation and alters cervical mucus and endometrial receptivity.
One tablet orally once daily at the same time each day for 21 days, followed by 7 placebo tablets. Each tablet contains ethinyl estradiol 0.02 mg and norethindrone acetate 1 mg.
One tablet (ethinyl estradiol 0.03 mg, levonorgestrel 0.15 mg) orally once daily at the same time each day for 21 days, followed by 7 placebo tablets. For continuous cycling, may take active tablets daily without placebo.

Norethindrone: ~8–11 hours (terminal); ethinyl estradiol: ~13–19 hours (terminal). Steady-state achieved within 5–7 days.
Terminal elimination half-life of ethinyl estradiol is 13-27 hours (mean 17 hours); for norgestimate, active metabolite norelgestromin has half-life 12-30 hours (mean 19 hours). Steady state reached after 7-14 days.
Renal (30–40% as metabolites, <5% unchanged); biliary/fecal (40–60% as metabolites).
Approximately 40% renal (as metabolites), 32% fecal (as metabolites), and <1% unchanged in urine.
