BANZEL vs DEPAKOTE CP
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.
Valproate increases GABA concentration in the brain by inhibiting GABA transaminase and succinic semialdehyde dehydrogenase. It also blocks voltage-gated sodium channels and T-type calcium channels.
400 mg orally twice daily, titrated by 400 mg increments every 2 weeks to a maximum of 1600 mg twice daily.
250-500 mg orally twice daily, titrated by 250 mg/day every 3-7 days; maximum 60 mg/kg/day. Target trough serum concentration: 50-100 mcg/mL.

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 elimination half-life is 9-16 hours (mean ~12 hours) in adults; prolonged in hepatic impairment, elderly, and neonates.
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: 30-50% as glucuronide conjugates, 3% as unchanged drug; fecal: minimal; less than 3% excreted in bile.
