Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective enhancement of slow inactivation of voltage-gated sodium channels, stabilizing neuronal membranes and inhibiting excitatory neurotransmitter release.
Irreversible inhibitor of GABA transaminase (GABA-T), leading to increased brain concentrations of gamma-aminobutyric acid (GABA).
Initial: 50 mg orally once daily; titrate at weekly intervals by 50 mg twice daily increments to maintenance dose of 200 mg twice daily (400 mg/day). Maximum: 400 mg twice daily (800 mg/day).
Adults: 500 mg orally twice daily, may increase by 500 mg/day every week; maximum 1500 mg twice daily.

Terminal elimination half-life ranges from 20 to 48 hours (mean ~32 hours). Steady-state achieved within 5-7 days.
Terminal elimination half-life: 5-7 hours in young adults; 12-15 hours in elderly; therapeutic steady-state achieved within 2-3 days.
Primarily eliminated by hepatic metabolism, with approximately 95% excreted as metabolites in urine and <2% as unchanged drug. Fecal excretion accounts for about 5%.
Renal: 70% unchanged; hepatic metabolism: 20% (primarily via CYP4A7, not CYP450); fecal: <5%.
