# GLP-1 receptor agonists reduce alcohol use disorder risk by 28-36 percent across diverse populations as demonstrated by meta-analysis of 5.26 million patients

A systematic review and meta-analysis published in eClinicalMedicine synthesized 14 studies (4 RCTs and 10 observational studies) encompassing 5.26 million patients to assess GLP-1 receptor agonist effects on alcohol consumption. The analysis found three convergent signals: (1) AUDIT score reduction of 7.81 points (95% CI −9.02 to −6.60), representing clinically meaningful improvement in alcohol use severity; (2) 36% reduction in alcohol-related events including AUD incidence, recurrence, hospitalizations, and acute intoxication (HR 0.64, 95% CI 0.59–0.69); and (3) 28% lower risk of AUD diagnosis (HR 0.72, 95% CI 0.59–0.89). Semaglutide and liraglutide showed the most consistent effects. Critically, the study population was primarily metabolic patients (T2D/obesity) prescribed GLP-1s for metabolic indications, not treatment-seeking AUD patients. This creates a natural experiment demonstrating real-world effectiveness separate from the treatment-seeking context of SEMALCO. Objective biomarkers confirmed the behavioral findings: PEth (phosphatidylethanol) and γ-GT (gamma-glutamyltransferase) reductions validated reduced alcohol consumption. Neuroimaging studies within the meta-analysis showed attenuated alcohol cue reactivity and dopaminergic signaling with GLP-1 use, providing mechanistic confirmation that GLP-1 modulates reward salience through VTA dopamine pathways, not merely appetite suppression. The high heterogeneity (I² = 87.5%) reflects diverse study designs and populations, but directional consistency across all 14 studies strengthens the finding. Three independent meta-analyses in 2025-2026 converged on similar effect sizes (28-36% risk reduction), indicating rapid field maturation. The convergence of RCT efficacy evidence (SEMALCO) with real-world effectiveness evidence (this meta-analysis) across different populations is unusual for such a new therapeutic application and elevates confidence beyond single-study findings.
