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 oral contraceptive. Suppresses gonadotropin release, inhibiting ovulation. Increases cervical mucus viscosity and alters endometrial receptivity.
100 mg orally once daily with food.
One tablet orally once daily, taken at the same time each day. Each tablet contains norethindrone 0.5 mg/ethinyl estradiol 35 mcg for days 1-7, norethindrone 0.75 mg/ethinyl estradiol 35 mcg for days 8-14, and norethindrone 1 mg/ethinyl estradiol 35 mcg for days 15-21, followed by 7 placebo tablets.

Terminal elimination half-life is approximately 12-15 hours in healthy adults; prolonged in renal impairment (up to 30 hours in severe impairment).
Norelgestromin terminal half-life is approximately 28 hours; ethinyl estradiol terminal half-life is approximately 17 hours. The extended half-life supports once-weekly dosing.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
Renal excretion of metabolites (primarily ethinyl estradiol and norelgestromin conjugates) accounts for approximately 50% of elimination; fecal/biliary excretion accounts for the remainder (about 35-40% fecal, 10-15% biliary).
