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: suppresses gonadotropin release via estrogen and progestin, inhibiting ovulation, thickening cervical mucus, and altering endometrial lining.
100 mg orally once daily with food.
One tablet (norgestrel 0.3 mg, ethinyl estradiol 0.03 mg) orally once daily for 21 consecutive days, followed by 7 days of placebo.

Terminal elimination half-life is approximately 12-15 hours in healthy adults; prolonged in renal impairment (up to 30 hours in severe impairment).
Ethinyl estradiol: terminal half-life 13-27 hours (mean ~17 hours); norgestrel: terminal half-life 11-45 hours (mean ~24 hours). Clinical context: steady-state reached within 5-7 days; accumulation minimal with daily dosing.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
Renal: ~40% as metabolites; fecal: ~60% via biliary excretion, primarily as glucuronide and sulfate conjugates.
