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 estrogen-progestin contraceptive. Suppresses gonadotropin release, inhibits ovulation, increases cervical mucus viscosity, and alters endometrial morphology.
One tablet orally once daily, each containing 1 mg norethindrone acetate and 35 mcg ethinyl estradiol.
5 mg orally once daily for 20 days starting on day 5 of menstrual cycle

Norethindrone: 5-14 hours (mean 8 hours); ethinyl estradiol: 10-20 hours (mean 14 hours). Clinical context: steady-state achieved within 5-7 days.
Norethynodrel: 5-10 hours; mestranol: 2-5 hours (metabolized to ethinyl estradiol, half-life 10-20 hours). Steady-state reached in 5-7 days.
Renal (55-60% as metabolites, 25-30% as unchanged drug and conjugates), biliary/fecal (30-35% as metabolites).
Renal (50-60% as metabolites, <1% unchanged); fecal (40-50%)
