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.
Tri-Lo Sprintec is a combination oral contraceptive containing ethinyl estradiol and norgestimate. It inhibits ovulation by suppressing gonadotropin release (FSH and LH) from the pituitary, increases viscosity of cervical mucus, and alters endometrial receptivity.
100 mg orally once daily with food.
One tablet (0.035 mg ethinyl estradiol + 0.180/0.215/0.250 mg norgestimate) orally once daily for 28-day cycle: active tablets on days 1-21, placebo on days 22-28.

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 approximately 17 hours. Norelgestromin (active metabolite of norgestimate): terminal half-life approximately 28 hours. Clinical context: Ethinyl estradiol half-life supports once-daily dosing with steady-state reached within 7-14 days; norelgestromin half-life allows for sustained progestogenic effect.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
Renal (approximately 50-60% as metabolites, with about 20% as unchanged ethinyl estradiol glucuronide and 40% as norgestimate metabolites). Fecal (approximately 30-40% as metabolites).
