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 α2-δ subunit of voltage-gated calcium channels, reducing calcium influx and inhibiting release of excitatory neurotransmitters including glutamate, norepinephrine, and 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).
Oral: 75-150 mg twice daily or 50-100 mg three times daily; maximum 600 mg/day. Start at 75 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 is 6.3 hours (range 5.5–6.7 hours) in patients with normal renal function. Half-life increases in renal impairment (up to 48 hours in anuria).
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 excretion of unchanged drug accounts for approximately 90% of elimination; less than 1% is secreted in feces or bile. Dose adjustment required in renal impairment (CrCl <60 mL/min).
