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 an estrogen (ethinyl estradiol) and a progestin (norethindrone). Suppresses gonadotropin-releasing hormone (GnRH) from the hypothalamus, reducing luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion from the pituitary, thereby inhibiting ovulation. Additionally, induces changes in cervical mucus (impenetrability to sperm) and endometrium (reduced likelihood of implantation).
One tablet orally once daily at the same time each day for 28 consecutive days.
One tablet orally once daily, each containing 1 mg norethindrone acetate and 35 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.
Norethindrone: 5-14 hours (mean 8 hours); ethinyl estradiol: 10-20 hours (mean 14 hours). Clinical context: steady-state achieved within 5-7 days.
Renal: ~50-60% as metabolites, <10% unchanged; Fecal: ~40-50% via bile; Ethinyl estradiol undergoes enterohepatic recirculation.
Renal (55-60% as metabolites, 25-30% as unchanged drug and conjugates), biliary/fecal (30-35% as metabolites).
