LACOSAMIDE vs ZONEGRAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selectively enhances slow inactivation of voltage-gated sodium channels, stabilizing hyperexcitable neuronal membranes and inhibiting repetitive neuronal firing.
Anticonvulsant; blocks voltage-gated sodium and calcium channels, enhances GABA-mediated inhibition, and inhibits glutamate release.
Oral or IV: 50 mg twice daily initially; increase by 50 mg twice daily weekly to maintenance 100-200 mg twice daily. Maximum 200 mg twice daily.
Initial: 100 mg orally once daily for 2 weeks, then may increase by 100 mg/day at 2-week intervals; usual maintenance: 200-400 mg/day divided once or twice daily; maximum: 600 mg/day.

Terminal elimination half-life is approximately 13 hours (range 12–16 hours) in adults. Steady state achieved after 3 days with BID dosing.
Terminal elimination half-life is approximately 63 hours (range 50-70 hours) in adults. The long half-life allows for once- or twice-daily dosing. Steady state is reached after about 2 weeks of repeated dosing.
Renal: approximately 95% (40% unchanged, remainder as O-desmethyl metabolite). Fecal: <5%.
Renal: approximately 62% of the dose as unchanged drug and metabolites (primarily glucuronide conjugates and N-acetylzonisamide). Fecal: approximately 16% (including metabolites). Biliary excretion is minimal. Total recovery in urine and feces accounts for ~80% of the dose.
