BANZEL vs LYRICA CR
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.
Binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, reducing calcium influx and inhibiting excitatory neurotransmitter release (e.g., glutamate, norepinephrine, substance P).
400 mg orally twice daily, titrated by 400 mg increments every 2 weeks to a maximum of 1600 mg twice daily.
Initial 75 mg orally twice daily (150 mg/day), or 50 mg three times daily (150 mg/day). Based on efficacy and tolerability, may increase to 150 mg twice daily (300 mg/day) after 1 week, then to 225 mg twice daily (450 mg/day) if needed. Maximum dose 450 mg/day. Take with food. Administer whole; do not split, crush, or chew.

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.
6.3 hours (mean terminal elimination half-life); correlates with creatinine clearance, prolonged in renal impairment.
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.
Primarily renal excretion as unchanged drug (98-99% of absorbed dose); <0.1% biliary/fecal.
