A recent study has revealed that semaglutide, the active ingredient found in the GLP-1 medications Ozempic and Wegovy, may significantly reduce alcohol cravings and the frequency of heavy drinking days for individuals with Alcohol Use Disorder (AUD). This groundbreaking research was published in the journal JAMA Psychiatry, shedding light on a potential new treatment avenue for a condition affecting approximately 400 million people globally.
The study involved participants who were administered semaglutide injections over a designated period. Results indicated that those receiving the medication experienced a marked decrease in weekly alcohol cravings, average drinks consumed during drinking days, and the number of heavy drinking days compared to those taking a placebo. Notably, about 40% of the semaglutide group reported having no heavy drinking days in the final month of treatment.
Despite these encouraging results, the study's focus on AUD has raised concerns among some experts. While there are several FDA-approved medications available for alcohol and opioid use disorders, no approved treatments currently exist for methamphetamine, cocaine, or other stimulant use disorders.
“The study’s limitations such as small sample size, short study duration, and the fact that participants were not actively seeking treatment may suggest that the results may not fully translate to a real-world clinical setting,” an unnamed source stated. This emphasizes the need for further research to validate the findings.
J. Greg Hobelmann, MD, MPH, expressed his enthusiasm for the study, saying, “I am thrilled to see this study.” However, he cautioned against relying solely on anecdotal evidence, stating, “There has been a lot of hype about semaglutide (and other incretin mimetics), but we ought not base treatment on intuition and anecdotal reports.”
The necessity for alternative treatment options for AUD is evident. Currently, only about 2% of individuals diagnosed with AUD utilize medicinal treatments. Terrence Walton, MSW, highlighted this need for diversity in treatment options, saying, “I am always encouraged when I learn of a new tool for treating any substance use disorder, whether that is a psychosocial intervention or a pharmaceutical.” He expressed mild disappointment that the study focused solely on AUD but acknowledged the potential implications of validating anecdotal reports on reductions in cravings.
The study's findings could enhance accessibility and acceptance of treatment for AUD. Abdullah noted that “the reduction in alcohol craving and heavy/binge drinking days is particularly important as cravings are a significant factor for relapse.” He added that having an alternative treatment option could diminish stigma associated with AUD treatments.
Moreover, semaglutide's established presence in general medical settings may facilitate broader acceptance among healthcare providers and patients alike. This accessibility is crucial given the prevalence of AUD and its associated consequences, which include occupational dysfunction, relationship harm, and various severe medical conditions.
The authors of the study underscored the importance of personalized treatment approaches for AUD, as it is known to be highly heterogeneous. A "one size fits all" strategy is unlikely to yield optimal results. Future studies will need to incorporate a larger sample size and a more varied dosage to fully understand semaglutide's efficacy in treating AUD.
“I am looking forward to the next phase,” Walton said, anticipating more comprehensive studies that include participants with severe alcohol use disorder who are actively seeking treatment. He emphasized the need for future research to address this population's unique challenges.
Fenno highlighted the importance of high-quality studies to determine the true efficacy of GLP-1 medications like semaglutide on alcohol consumption. “We need high quality studies with direct clinical utility to know whether the rumors are true, and if so, how to use this class of medications effectively and with which patients,” Fenno stated.
