Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination oral contraceptive containing norethindrone acetate and ethinyl estradiol. Norethindrone acetate is a progestin that suppresses gonadotropin release, inhibiting ovulation; ethinyl estradiol is an estrogen that provides feedback inhibition of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), preventing follicular development and ovulation. Additionally, it causes changes in cervical mucus (increased viscosity) and endometrium (reduced receptivity).
Combination of ethinyl estradiol, an estrogen, and desogestrel, a progestin, which inhibit gonadotropin release (FSH and LH) from the pituitary, suppressing ovulation and altering cervical mucus and endometrial lining to reduce likelihood of fertilization and implantation.
One tablet orally once daily at the same time each day for 28 consecutive days.
One tablet orally once daily for 21 days, followed by 7 days of placebo (iron-containing) tablets. Each active tablet contains 0.1 mg levonorgestrel and 20 mcg ethinyl estradiol.

Norethindrone: 5-14 hours (terminal); Ethinyl estradiol: 10-20 hours (terminal). Steady-state achieved within 5-7 days; contraceptive efficacy maintained with daily dosing.
Ethinyl estradiol: ~12-14 hours; norethindrone: ~7-8 hours; both allow once-daily dosing with steady-state reached within 7-10 days.
Renal: ~50-60% as metabolites, <10% unchanged; Fecal: ~40-50% via bile; Ethinyl estradiol undergoes enterohepatic recirculation.
Renal: ~50-60% as metabolites; fecal: ~40-50% via biliary elimination; less than 10% unchanged in urine.
