| Summary: | <b>Background/Objectives</b>: Emerging evidence suggests an association between glucagon-like peptide-1 (GLP-1) receptor agonists and sodium–glucose co-transporter 2 (SGLT2) inhibitors with altered risk of damage in the inner ear system. However, limited research exists on the relationship between these medications and subsequent irreversible hearing loss. We conducted this network meta-analysis (NMA) to evaluate the comparative risk of hearing loss associated with such medications. <b>Methods</b>: In this NMA, we used a confirmatory approach to specifically focus on particular adverse effects of interest (i.e., incidence of hearing loss here) based on the Cochrane recommendation. A Bayesian-based NMA of randomized controlled trials (RCTs) of GLP-1 receptor agonists or SGLT2 inhibitors was conducted. The primary outcome was the hearing loss events. <b>Results</b>: Our NMA of 29 RCTs with 145,895 participants found that only two exendin-4 derivatives—lixisenatide and high-dose efpeglenatide (i.e., 6 mg/week)—showed increased hearing loss events compared to controls. No other GLP-1 receptor agonists or SGLT2 inhibitors demonstrated significantly elevated hearing loss risk. Lixisenatide ranked highest in risk among all investigated regimens. <b>Conclusions</b>: This comprehensive NMA identifies a significant association between exendin-4 derivatives (lixisenatide and efpeglenatide) and potential ototoxicity. Clinicians should carefully consider this potential ototoxicity when prescribing exendin-4 derivatives, particularly in patients with pre-existing hearing loss risk factors. |
