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.
Oral contraceptive: inhibition of ovulation by suppressing gonadotropin release; increases viscosity of cervical mucus, reducing sperm penetration; alters endometrial receptivity.

Terminal elimination half-life is approximately 12-15 hours in healthy adults; prolonged in renal impairment (up to 30 hours in severe impairment).
Terminal elimination half-life: 24-30 hours; clinical context: steady-state reached after 5-7 days, allows once-daily dosing
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
