Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases GABAergic activity by inhibiting GABA transaminase and succinate semialdehyde dehydrogenase; blocks voltage-gated sodium and T-type calcium channels; reduces glutamate release.
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).
500-1000 mg orally once daily; usual maximum dose 60 mg/kg/day.
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.

Terminal elimination half-life is approximately 20 hours (range 10-60 hours); clinical context: extended-release formulation allows once-daily dosing, steady-state achieved in 4-5 days
6.3 hours (mean terminal elimination half-life); correlates with creatinine clearance, prolonged in renal impairment.
Primarily renal (30-50% as glucuronide conjugates, <3% as unchanged drug); minor fecal (10-20%)
Primarily renal excretion as unchanged drug (98-99% of absorbed dose); <0.1% biliary/fecal.
