The Role of Glucagon-Like Peptide-1 Receptor Agonists in Prompting a Meaningful Improvement in Alcohol Use Disorder

Emerging research suggests a potential role for glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in alcohol use disorder (AUD), because GLP-1 receptors are present in the brain regions involved in dopamine signaling and the human reward system. We present the case of a man prescribed GLP-1 RAs for obesity who had concomitant AUD. A 34-year-old man was referred to a family medicine clinic for medication therapy management of obesity. His medical history was notable for bipolar disorder, class 2 obesity, and obstructive sleep apnea (OSA). His Alcohol Use Disorders Identification Test score indicated high-risk alcohol use. Over the course of 10 months using an injectable GLP-1 RA (semaglutide), the patient showed a clinically significant decrease in both body weight and alcohol consumption. Although this patient initially sought care for weight loss goals to improve quality of life and symptoms of OSA, after 10 months of treatment with semaglutide he reported a considerable decrease in alcohol consumption leading to mental, social, and home life improvements. Our aim in presenting this case is to illustrate the potential benefit of GLP-1 RAs for decreasing alcohol consumption levels in a patient with multiple comorbid conditions. The case adds to the growing body of evidence supporting the exploration of GLP-1 RAs for the treatment of AUD. Additionally, it underscores the need to enhance AUD screening efforts within family medicine clinics to identify high-risk persons and provide timely interventions.
