Resumo

Background: Cannabidiol (CBD) is one of the main nonpsychoactive components of Cannabis sativa and may represent an alternative treatment for Restless Legs Syndrome/Willis-Ekbom Disease (RLS/WED) in patients with Parkinson's disease (PD) and REM (Rapid Eye Movement) sleep behavior disorder (RBD).Objective: Our purpose was a post hoc exploratory analysis to evaluate the CBD's efficacy to improve the severity of RLS/WED symptoms in patients with PD and RBD.Methods: A post hoc exploratory analysis of a phase II/III, a parallel, double-blind, placebo-controlled clinical trial was conducted in 18 patients with RLS/WED and PD plus RBD associated. Six patients were randomized to the CBD group in doses of 75-300 mg, and twelve received placebo capsules. They were followed up for 14 weeks. The primary outcome was the severity of RLS/WED by Restless Legs Syndrome Rating Scale of the International Restless Legs Syndrome Study Group (IRLSSG).Results: CBD showed no difference in relationship to placebo for primary and secondary outcomes.Conclusion: CBD showed no reduction in the severity of RLS/WED manifestation in patients with PD and RBD.
