Objective:

To evaluate the efficacy of semaglutide, a GLP-1 receptor agonist, in reducing heavy drinking among patients with alcohol use disorder and obesity.

Key Findings:
  • Participants receiving semaglutide experienced a 41.1% reduction in heavy drinking days, which was 13.7% greater than the placebo group.
  • Blood-alcohol biomarkers corroborated self-reported reductions in drinking.
  • The GLP-1 group showed more significant decreases in body weight and blood pressure.
  • Semaglutide had a number needed to treat (NNT) of 4.3, indicating higher efficacy compared to existing medications for alcohol use disorder.
Interpretation:

The study suggests that GLP-1 receptor agonists like semaglutide may offer a promising new treatment option for individuals with alcohol use disorder and obesity, potentially addressing the treatment gap in this population.

Limitations:
  • The study's sample size was relatively small at 108 participants.
  • The duration of the trial was limited to 26 weeks.
Conclusion:

The findings support the potential of GLP-1s in treating alcohol use disorder, warranting further investigation in larger and longer-term studies.
