Cenobamate is a tetrazole carbamate anticonvulsant used as therapy of partial onset seizures in adults. Cenobamate is associated with a low-to-moderate rate of serum aminotransferase elevations during therapy and has been linked to cases of clinically apparent liver injury usually in the context of a multiorgan hypersensitivity syndrome such as drug reaction with eosinophilia and systemic symptoms (DRESS).
