Daily Avanafil for Erectile Dysfunction

Phase 4
Completed
Conditions
Erectile Dysfunction
Interventions
Drug: Placebo oral tablet
Registration Number
NCT04374994
Lead Sponsor
University of Alexandria
Brief Summary

In this study, the investigators tried to study the effect of daily avanafil on the serum level of endothelial function markers, as well as its impact on the erectile function in males with erectile and endothelial dysfunction by comparing the results with controls who received placebo.

Detailed Description

Avanafil is a highly selective and potent oral phosphodiesterase type 5 inhibitor (PDE5-I) . However, its impact on the soluble markers of endothelial function has not been investigated yet. This study was conducted to assess the effect of daily avanafil on the erectile function and endothelial markers' serum level. In this work we recruited males with erectile dysfunction and other diseases commonly associated with endothelial dysfunction. The investigators randomly treated patients with daily oral avanafil and the other patients with placebo. The investigators measured the International Index of Erectile Function -5 score (IIEF- 5) and the serum levels of markers of endothelial function at baseline and treatment.
