Evaluation of the Effect of Uridine Diphosphate-Glucuronosyltransferases (UGT) Inhibition by Valproic Acid on Vixotrigine Pharmacokinetics in Healthy Volunteers.


Vixotrigine is a voltage-dependent and use-dependent sodium channel blocker in development for the treatment of neuropathic pain. Metabolism of vixotrigine is primarily through glucuronidation, resulting in the major M13 metabolite. Two additional major metabolites formed are M14 and M16. This study was designed to evaluate the effects of a uridine diphosphate-glucuronosyltransferase inhibitor, valproic acid, on vixotrigine pharmacokinetics.
