BANZEL vs DIVALPROEX SODIUM
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.
Increases brain concentrations of gamma-aminobutyric acid (GABA), blocks voltage-gated sodium channels, and modulates 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.
10-15 mg/kg/day orally in divided doses; increase by 5-10 mg/kg/week; maximum 60 mg/kg/day. Extended-release: 25 mg/kg/day orally; increase by 15 mg/kg/day at weekly intervals; maximum 60 mg/kg/day.

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.
9-16 hours (terminal); shorter in children (6-9 hours) and longer in hepatic disease or elderly; clinical context: twice-daily dosing provides stable trough concentrations.
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: <3% unchanged; primarily hepatic metabolism (glucuronidation, beta-oxidation, cytochrome P450), metabolites eliminated renally; fecal: negligible.
