BANZEL vs LYRICA
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 α2-δ subunit of voltage-gated calcium channels, reducing calcium influx and inhibiting release of excitatory neurotransmitters including glutamate, norepinephrine, and substance P.
400 mg orally twice daily, titrated by 400 mg increments every 2 weeks to a maximum of 1600 mg twice daily.
Oral: 75-150 mg twice daily or 50-100 mg three times daily; maximum 600 mg/day. Start at 75 mg twice daily.

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 6.3 hours (range 5.5–6.7 hours) in patients with normal renal function. Half-life increases in renal impairment (up to 48 hours in anuria).
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 excretion of unchanged drug accounts for approximately 90% of elimination; less than 1% is secreted in feces or bile. Dose adjustment required in renal impairment (CrCl <60 mL/min).
