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.
Carbamazepine stabilizes inactivated state of voltage-gated sodium channels, thereby inhibiting repetitive neuronal firing and reducing synaptic transmission.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
200-400 mg orally twice daily; maximum 1200 mg/day for monotherapy, 1600 mg/day for combination therapy.

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.
Initial: 25-65 hours; chronic dosing: 12-17 hours due to autoinduction. Steady-state reached in 2-4 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: ~72% as unchanged drug and metabolites (primarily glucuronides). Fecal: ~28% via bile (enterohepatic recirculation possible).
