Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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).
Combination oral contraceptive containing ethinyl estradiol and norethindrone. Suppresses gonadotropin release (FSH, LH) via estrogen and progestin negative feedback, inhibiting ovulation. Changes cervical mucus viscosity and endometrial lining to impede sperm penetration and implantation.
One tablet orally once daily, each containing 1 mg norethindrone acetate and 35 mcg ethinyl estradiol.
One tablet (norethindrone acetate 1.5 mg, ethinyl estradiol 30 mcg) orally once daily.

Norethindrone: 5-14 hours (mean 8 hours); ethinyl estradiol: 10-20 hours (mean 14 hours). Clinical context: steady-state achieved within 5-7 days.
EE: terminal half-life ~17 ± 8 hours; NET: terminal half-life ~8 ± 1 hours. Steady-state achieved within ~2-3 cycles.
Renal (55-60% as metabolites, 25-30% as unchanged drug and conjugates), biliary/fecal (30-35% as metabolites).
Ethinyl estradiol (EE) and norethindrone (NET) are excreted in urine (40-60% as metabolites) and feces (20-30% as metabolites). NET is also excreted in bile and undergoes enterohepatic recirculation.
