Effects of cannabidiol plus naltrexone on motivation and ethanol consumption.

British Journal of Pharmacology banner

“The aim of this study was to explore if the administration of naltrexone (NTX) together with cannabidiol (CBD) may improve the efficacy in reducing alcohol consumption and motivation rather than any of the drugs given separately.

The administration of CBD + NTX significantly reduced motivation and ethanol intake in the oral self-administration procedure in a greater proportion than the drugs given alone. Only the combination of both drugs significantly reduced Oprm1, TH and 5-HT1A gene expressions in the NAc, VTA and DR, respectively. Interestingly, the administration of WAY100635 significantly blocked the actions of CBD + NTX but had no effects by itself.

CONCLUSION AND IMPLICATIONS:

The combination of low doses of CBD plus NTX resulted more effective to reduce ethanol consumption and motivation to drink. These effects, appears to be mediated, at least in part, by 5-HT1A receptors.”

Naltrexone belongs to a class of drugs known as opiate antagonists. It works in the brain to prevent opiate effects (e.g., feelings of well-being, pain relief). It also decreases the desire to take opiates. This medication is also used to treat alcohol abuse. It can help people drink less alcohol or stop drinking altogether. It also decreases the desire to drink alcohol when used with a treatment program that includes counseling, support, and lifestyle changes.” https://www.webmd.com/drugs/2/drug-7399/naltrexone-oral/details

“Cannabidiol reduces ethanol consumption, motivation and relapse in mice. Taken together, these results reveal that the administration of CBD reduced the reinforcing properties, motivation and relapse for ethanol. These findings strongly suggest that CBD may result useful for the treatment of alcohol use disorders.”   https://www.ncbi.nlm.nih.gov/pubmed/28194850
