Abstract
Background: Previous studies have confirmed the efficacy of phosphodiesterase type 5 inhibitors (PDE-5 inhibitors) in treating diabetic erectile dysfunction (DED), but they still have research value in terms of efficacy comparison and individualized safety. This study, while evaluating safety and efficacy, also focused on the sources of heterogeneity and innovatively explored the nonlinear relationship between therapeutic effect and age.
Aim: This study aimed to systematically evaluate the safety and efficacy of PDE-5 inhibitors for the treatment of DED and the related application effects and to provide a clinical basis for its treatment.
Methods: By searching PubMed, Embase, Web Of Science, Cochrane Library, China Knowledge Network (CNKI), Wipro (VIP), Wanfang, and China Biomedical Literature Database (CBM) before December 31, 2024, and reading the retrieved articles and references, PDE-5 inhibitors for diabetic erectile dysfunction in randomized controlled trials (RCTs). The literature of the included studies was evaluated using the Cochrane Literature Quality Assessment Tool. The meta-analysis was registered to PROSPERO (CRD42025637725).
Outcomes: The International Index of Erectile Function (IIEF-5) overall and related evaluation questionnaires were used as the primary efficacy evaluation indicators, and adverse events were used as secondary indicators.
Results: Meta-analysis was performed using Rever Manager 5.3 and STATA18 software. A total of 10 studies were included, and random-effects model meta-analysis analyzed the post-treatment efficacy of the 10 articles with a combined RR = 2.91, 95% CI of [1.95-4.34], P < 0.001. Fixed-effects model meta-analysis investigated adverse effects with RR = 2.0, 95% CI of [1.53-2.61], P < 0.001. There was a non-linear relationship between age and PDE-5 inhibitors.
Conclusion: PDE-5 inhibitors can safely and effectively improve diabetic erectile dysfunction, but the degree of effectiveness of different types of drugs, the occurrence of related adverse effects, and the differences that exist between individuals still need to be taken into account during use.
