Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Phenytoin stabilizes neuronal membranes by promoting voltage-gated sodium channel inactivation, reducing high-frequency neuronal firing and seizure propagation.
Selectively enhances slow inactivation of voltage-gated sodium channels, stabilizing hyperexcitable neuronal membranes and inhibiting repetitive neuronal firing.
300-400 mg per day orally in divided doses (e.g., 100 mg three times daily); loading dose 1 g orally divided into three doses given at 2-hour intervals, then 100 mg every 6-8 hours for first 24 hours.
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.

Clinical Note
moderateLacosamide + Sulfisoxazole
"The serum concentration of Sulfisoxazole can be increased when it is combined with Lacosamide."
Clinical Note
moderateLacosamide + Fluconazole
"The serum concentration of Fluconazole can be increased when it is combined with Lacosamide."
Clinical Note
moderateLacosamide + Ketoconazole
"The serum concentration of Ketoconazole can be increased when it is combined with Lacosamide."
Clinical Note
moderateLacosamide + Delavirdine
Terminal half-life: 7-42 hours (mean 22 hours) in adults; dose-dependent due to saturable metabolism. Steady-state reached in 7-10 days.
Terminal elimination half-life is approximately 13 hours (range 12–16 hours) in adults. Steady state achieved after 3 days with BID dosing.
Renal: 70% as metabolites (mainly HPPA glucuronide and sulfate), 5-10% as unchanged drug. Fecal: 30% (minor).
Renal: approximately 95% (40% unchanged, remainder as O-desmethyl metabolite). Fecal: <5%.
