Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABA concentration in the brain by inhibiting GABA transaminase and blocking voltage-gated sodium channels; also modulates histone deacetylase activity.
Irreversible inhibitor of GABA transaminase (GABA-T), leading to increased brain concentrations of gamma-aminobutyric acid (GABA).
Oral: Initial 15 mg/kg/day divided into 1-3 doses, increase by 5-10 mg/kg/day weekly; typical maintenance 30-60 mg/kg/day. Intravenous: Same total daily dose as oral, administered as continuous infusion or divided q6h.
Adults: 500 mg orally twice daily, may increase by 500 mg/day every week; maximum 1500 mg twice daily.

10-16 hours (monotherapy); 5-9 hours in patients on enzyme-inducing co-medications; prolonged in hepatic impairment (up to 30 hours) or neonates.
Terminal elimination half-life: 5-7 hours in young adults; 12-15 hours in elderly; therapeutic steady-state achieved within 2-3 days.
Renal: <3% unchanged; primarily hepatic metabolism via glucuronidation (50%) and beta-oxidation (40%), with metabolites excreted renally. Fecal: negligible.
Renal: 70% unchanged; hepatic metabolism: 20% (primarily via CYP4A7, not CYP450); fecal: <5%.
