BANZEL vs DILANTIN-125
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BANZEL (rufinamide) is a triazole derivative that modulates the activity of voltage-gated sodium channels. It prolongs the inactive state of sodium channels, thereby stabilizing neuronal membranes and inhibiting the repetitive firing of action potentials.
Phenytoin stabilizes neuronal membranes by promoting voltage-gated sodium channel inactivation, reducing high-frequency neuronal firing and seizure propagation.
400 mg orally twice daily, titrated by 400 mg increments every 2 weeks to a maximum of 1600 mg twice daily.
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.

Terminal elimination half-life is approximately 6-10 hours in adults; in pediatric patients, it is shorter (~3-6 hours). Steady-state is reached within 1-2 days.
Terminal half-life: 7-42 hours (mean 22 hours) in adults; dose-dependent due to saturable metabolism. Steady-state reached in 7-10 days.
Primarily renal: approximately 66% of the dose excreted in urine (30% as unchanged rufinamide, 70% as inactive metabolites). Fecal excretion: ~4%. No significant biliary excretion.
Renal: 70% as metabolites (mainly HPPA glucuronide and sulfate), 5-10% as unchanged drug. Fecal: 30% (minor).
