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 estrogen-progestin contraceptive; suppresses gonadotropin release, inhibiting ovulation, and alters cervical mucus and endometrial lining.
100 mg orally once daily with food.
One tablet (norethindrone 1 mg and ethinyl estradiol 50 mcg) orally once daily for 21 days followed by 7 days of placebo or no 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: 5-14 hours (terminal); ethinyl estradiol: 7-20 hours. Clinical context: Steady-state reached within 5-7 days; half-life allows once-daily dosing with stable contraceptive efficacy.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
Renal: 40-60% (metabolites, primarily glucuronide conjugates; <1% unchanged). Fecal: 30-50% (via biliary elimination).
