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.
Voltage-gated sodium channel blocker; stabilizes neuronal membranes and inhibits repetitive firing. Also inhibits glutamate release and enhances GABA activity.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
Initial: 200 mg orally twice daily; increase by 200 mg/day at weekly intervals. Maintenance: 800-1200 mg/day in 2-4 divided doses. Maximum dose: 1600 mg/day. Extended-release: 200-400 mg twice daily.

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.
Single dose: 25–65 hours (mean ~35 h); chronic therapy: 12–17 hours due to autoinduction; clinical context: requires 3–4 weeks to reach steady-state after dose adjustment.
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%).
Primarily hepatic metabolism; ~72% excreted in urine (as metabolites, <2% unchanged), ~28% excreted in feces via bile.
