摘要

Cenobamate is a novel antiseizure medication (ASM) commercially available in Europe and in the U.S. for the treatment of focal seizures in adults. The mechanisms responsible for its antiseizure activity include enhancement of the inactivated state of voltage-gated sodium channels with blockade of the persistent sodium current and positive allosteric modulation of GABAA receptors at a non-benzodiazepine binding site. Cenobamate has a high oral bioavailability that is not influenced by food intake. The terminal half-life is 50-60 hours, allowing for once-daily dosing. Cenobamate is a CYP2C19 inhibitor and an inducer of CYP3A4 and CYP2B6, and consequently, it can cause a number of drug-drug interactions. Efficacy and safety have been evaluated in two randomized, double-blind, placebo-controlled adjunctive therapy trials in adults with focal seizures. In both trials, cenobamate decreased significantly the frequency of focal seizures, with relatively high seizure freedom rates. Adverse events most commonly reported in double-blind trials included dizziness, somnolence, headache, fatigue, and diplopia. The occurrence of three cases of drug reaction with eosinophilia and systemic symptoms (DRESS) during early clinical development led to the conduction of a Phase 3 open-label long-term safety study in a total of 1339 patients. In this study, no serious idiosyncratic adverse reactions were observed using a start-low and go-slow approach. Further studies are required to determine whether the clinical activity profile of cenobamate extends to protection against other seizure types and to evaluate its efficacy and safety profile in special patient groups such as infants, children, the elderly, and patients with comorbid conditions.
