Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Norepinephrine and dopamine reuptake inhibitor; also weakly inhibits serotonin reuptake. Enhances synaptic concentrations of norepinephrine and dopamine, particularly in prefrontal cortex.
Combination oral contraceptive containing norethindrone acetate (progestin) and ethinyl estradiol (estrogen). Inhibits ovulation via suppression of gonadotropins (FSH, LH). Increases cervical mucus viscosity, reducing sperm penetration. Norethindrone acetate is metabolized to norethindrone, which binds to progesterone receptors; ethinyl estradiol binds to estrogen receptors, providing contraceptive effect and cycle control.
100 mg orally once daily with food.
1 tablet orally once daily, starting on day 1 of menstrual cycle; each tablet contains norethindrone acetate 1 mg and ethinyl estradiol 20 mcg (21 active tablets) followed by 7 ferrous fumarate tablets.

Terminal elimination half-life is approximately 12-15 hours in healthy adults; prolonged in renal impairment (up to 30 hours in severe impairment).
Norethindrone: 7-8 hours; ethinyl estradiol: 13-14 hours. Clinical context: steady-state in 5-7 days.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
Renal 60-80% as metabolites, fecal 20-30% via bile, unchanged drug <5%.
