Efficacy and safety of GLP-1 receptor agonists in the management of obstructive sleep apnea in individuals without diabetes: A systematic review and meta-analysis of randomized, placebo-controlled trials.

INTRODUCTION

Obstructive sleep apnea (OSA) is a common sleep disorder that disrupts breathing during sleep. While continuous positive airway pressure therapy is the standard treatment, poor adherence has led to exploration of alternative treatments. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been shown to reduce body weight and may help manage OSA. This systematic review and meta-analysis evaluated the efficacy and safety of GLP-1 RAs in individuals with OSA and elevated body weight who are without diabetes.

METHODS

A systematic search was conducted in September 2024 across multiple databases. Randomized controlled trials (RCTs) evaluating GLP-1 RAs for OSA in adults with a body mass index (BMI) ≥30 kg/m2 were included. The primary outcomes were changes in the apnea-hypopnea index (AHI) and overall adverse events. Meta-analyses were performed using a random-effects model.

RESULTS

Three RCTs were included in the analysis. Pooled results showed that GLP-1 RA treatment significantly reduced AHI compared to placebo, with a weighted mean difference (WMD) of -16.6 events per hour (95 % confidence interval [CI]: -27.9 to -5.3). However, GLP-1 RAs were associated with a higher frequency of adverse events, with an odds ratio (OR) of 1.62 (95 % CI: 1.16 to 2.24) compared to placebo.

CONCLUSION

GLP-1 RAs effectively reduce OSA severity, offering a promising alternative for individuals with OSA and elevated body weight. However, the increased risk of side effects must be considered. Further long-term studies are needed to confirm the sustained benefits and safety of GLP-1 RAs in OSA management.
