Abstract

Background: The impact of Antidiabetic Agents on COPD Exacerbations remains uncertain. We conducted a comprehensive review to evaluate the impact Antidiabetic Agents on COPD Exacerbations in patients with T2DM.

Methods: We searched PubMed, Embase, and Web of Science from inception to January 15, 2026 for observational studies involving adults with T2DM and COPD. Risk ratios (RRs) with 95% confidence intervals (CIs) were pooled using random-effects models, treatments were ranked using the Surface Under the Cumulative Ranking Curve (SUCRA), and study quality was assessed using the Newcastle–Ottawa Scale.

Results: Thirteen studies comprising 755,206 participants were included. Compared with sulfonylureas, SGLT-2 inhibitors were associated with the lowest risk of overall COPD exacerbations (RR 0.71, 95% CI 0.66–0.77), followed by GLP-1 receptor agonists (RR 0.77, 95% CI 0.71–0.84). Metformin demonstrated a near-neutral association (RR 0.89, 95% CI 0.79–1.00), whereas DPP-4 inhibitors (RR 1.05, 95% CI 0.97–1.13) and meglitinides (RR 1.13, 95% CI 0.93–1.36) showed no evidence of benefit. Similar findings were observed for severe exacerbations, with SGLT-2 inhibitors and GLP-1 receptor agonists demonstrating the strongest associations.

Conclusions: SGLT-2 inhibitors and GLP-1 receptor agonists were associated with a lower risk of COPD exacerbations than sulfonylureas, whereas metformin showed a near-neutral association and DPP-4 inhibitors and meglitinides showed no clear benefit.
