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.
Irreversible inhibitor of GABA transaminase, increasing brain GABA levels.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
Adults: 50 mg/kg/day orally divided twice daily; maximum dose 3 g/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 6-8 hours in adults; in neonates, it is prolonged to 16-20 hours due to immature renal function.
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 excretion of unchanged drug accounts for approximately 65-70% of elimination; biliary/fecal excretion is minimal (<5%).
