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: ethinyl estradiol and norgestrel inhibit ovulation via suppression of gonadotropins (LH, FSH); increase viscosity of cervical mucus, impairing sperm penetration; alter endometrial structure, reducing implantation likelihood.
100 mg orally once daily with food.
One tablet (norgestrel 0.3 mg/ethinyl estradiol 30 mcg) orally once daily at the same time each day for 28 days, with 21 active tablets followed by 7 inactive tablets.

Terminal elimination half-life is approximately 12-15 hours in healthy adults; prolonged in renal impairment (up to 30 hours in severe impairment).
Norgestrel: ~45 hours (terminal). Ethinyl estradiol: ~13 hours (terminal). Steady-state achieved within 5-7 days.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
Renal 50-60% as metabolites, fecal 40-50% via biliary elimination. Ethinyl estradiol undergoes enterohepatic recirculation.
