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.
Increases seizure threshold by modulating voltage-gated sodium channels and enhancing GABA-ergic inhibition.
Adults: 200-800 mg twice daily orally, starting at 200 mg twice daily, increasing by 200 mg/day weekly to maintenance.
300-600 mg orally three times daily; titrate to seizure control.

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.
16-24 hours (trimethadione); dimethadione (active metabolite) has a half-life of ~6-12 days, leading to drug accumulation.
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: ~70% as unchanged drug and metabolites (including dimethadione); biliary/fecal: minimal (<10%).
