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.
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).
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).
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 ranges from 20 to 48 hours (mean ~32 hours). Steady-state achieved within 5-7 days.
6.3 hours (mean terminal elimination half-life); correlates with creatinine clearance, prolonged in renal impairment.
Primarily eliminated by hepatic metabolism, with approximately 95% excreted as metabolites in urine and <2% as unchanged drug. Fecal excretion accounts for about 5%.
Primarily renal excretion as unchanged drug (98-99% of absorbed dose); <0.1% biliary/fecal.
