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.
Binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, reducing calcium influx and inhibiting excitatory neurotransmitter release (e.g., glutamate, norepinephrine, substance P).
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.
Initial 75 mg orally twice daily (150 mg/day), or 50 mg three times daily (150 mg/day). Based on efficacy and tolerability, may increase to 150 mg twice daily (300 mg/day) after 1 week, then to 225 mg twice daily (450 mg/day) if needed. Maximum dose 450 mg/day. Take with food. Administer whole; do not split, crush, or chew.

10-16 hours (monotherapy); 5-9 hours in patients on enzyme-inducing co-medications; prolonged in hepatic impairment (up to 30 hours) or neonates.
6.3 hours (mean terminal elimination half-life); correlates with creatinine clearance, prolonged in renal impairment.
Renal: <3% unchanged; primarily hepatic metabolism via glucuronidation (50%) and beta-oxidation (40%), with metabolites excreted renally. Fecal: negligible.
Primarily renal excretion as unchanged drug (98-99% of absorbed dose); <0.1% biliary/fecal.
