Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity in the CNS by inhibiting presynaptic serotonin reuptake.
Stabilizes neuronal membranes and inhibits repetitive firing of action potentials via blockade of voltage-gated sodium channels; also enhances GABAergic activity and inhibits glutamate release.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
Initial dose 25 mg orally twice daily; titrate by 25-50 mg/day every 1-2 weeks to target dose of 200-400 mg/day in two divided doses. Maximum 400 mg/day.

Terminal elimination half-life is 20–30 hours in adults with normal renal function; prolonged to 40–60 hours in moderate to severe renal impairment (CrCl <50 mL/min), requiring dose adjustment.
Terminal elimination half-life is approximately 70-90 hours after multiple dosing, supporting twice-daily dosing; requires slow titration to steady state (2-3 weeks).
Renal excretion of unchanged drug accounts for approximately 70% of elimination, with 30% metabolized hepatically; metabolites are also renally excreted. Fecal elimination is minimal (<5%).
Renal: approximately 70% as unchanged drug; fecal: approximately 20%; biliary: minor (<5%).
