Perampanel in Parkinson Disease Fluctuations: A Double-Blind Randomized Trial With Placebo and Entacapone

Abstract

Objectives: Perampanel is a selective and noncompetitive alpha-amino-3-hydroxy-5-methylisoxazole propionic acid-type glutamate receptor antagonist that improves motor symptoms in animal models of Parkinson disease (PD). The aim of this study was to assess the efficacy and tolerability of perampanel in L-dopa-treated patients with moderately severe PD and motor fluctuations using an active comparator study design.
