The Efficacy and Neurobehavioural Mechanism of Cannabidiol (CBD) for Alcohol Dependence

Alcohol Use Disorder (AUD) Clinical Trial

Official title:
The Efficacy and Neurobehavioural Mechanism of Cannabidiol (CBD) for Alcohol Dependence: An Exploratory Pilot Study

Clinical Trial Summary

The study will explore the psychophysiological and neurobiological and mechanisms of CBD in participants with alcohol use disorder

Clinical Trial Description

New treatment strategies for treating symptoms of alcohol dependence are urgently needed. Although alcohol related disorders are a leading cause of preventable death in Australia, their treatment is generally not evidence based. Cannabidiol (CBD) may serve as a novel pharmacotherapeutic due to its anxiolytic, anti-epileptic, neuro-protective, antioxidant and neuroprotective properties as well as a particularly safe side effect profile. Further, CBD has been shown to modulate drug craving and seeking behaviours. This project will examine whether CBD exerts an effect on cue-induced craving by reducing activation in areas of the brain responsive to alcohol cues in comparison to a placebo. This study will use functional magnetic resonance imaging (fMRI) to examine activity in the brain while participants are exposed alcohol related cues and magnetic resonance spectroscopy (MRS) to determine levels of neurotransmitters that may be responsible for craving. In addition, we aim to investigate the effects of CBD on autonomic nervous system parameters associated with alcohol withdrawal symptoms and anxiety, such as heart rate variability and skin conductance. Additionally, clinical outcome measures will be taken to investigate CBDs influence on drinking, sleep This project uses a randomised, double blind, crossover design with 800mg CBD vs matched placebo. The dosing paradigm will consist of one dose per day for three days per arm with a 18 days washout period in-between arms. ;
