CENOBAMATE vs VIGPODER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cenobamate is a tetrazole-derived anticonvulsant that modulates GABA A receptors, preferentially inhibiting the persistent sodium current and activating potassium currents (M-current). It also enhances GABA-mediated inhibition and reduces excitatory neurotransmitter release.
VIGPODER (vigabatrin) is an irreversible inhibitor of GABA transaminase, leading to increased brain levels of gamma-aminobutyric acid (GABA), a major inhibitory neurotransmitter.
Cenobamate 200 mg orally once daily initially, titrated weekly by 50 mg to a target dose of 400 mg once daily; maximum 400 mg/day.
150 mg orally twice daily with or without food.

The terminal elimination half-life is approximately 10-17 hours in adults. Steady-state is achieved within 2-3 days. In patients with moderate to severe hepatic impairment, half-life may be prolonged.
12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in moderate renal impairment (CrCl 30–50 mL/min).
Renal excretion accounts for approximately 92% of the administered dose, with 62% as unchanged drug and 30% as metabolites. Fecal excretion is minimal (<2%).
Renal: 70% as unchanged drug; biliary/fecal: 20% as metabolites; 10% via other routes.
