EDEUS, a Real-Life Study on the Users of Phosphodiesterase Type 5 Inhibitors: Prevalence, Perceptions, and Health Care-Seeking Behavior Among European Men With a Focus on 2nd-Generation Avanafil.

INTRODUCTION

Erectile dysfunction (ED) is a multidimensional disorder with an estimated prevalence of 1% to 10% in men younger than 40 years and up to 100% in men in their 70s and 80s.

AIM

To evaluate the real-life characteristics and unmet needs of men with ED, its impact on well-being, and treatment rates across Europe.

METHODS

Adult men in Belgium, France, Germany, Italy, Poland, Portugal, and Spain were invited to participate in the survey. Men who did not use at least a drug for sexual health in the past 3 months, had cancer or spinal cord injuries, and/or underwent non-nerve-sparing radical prostatectomy were excluded.

MAIN OUTCOME MEASURES

The 15-item International Index of Erectile Function (IIEF-15) with study-specific, self-constructed questions was used.

RESULTS

Overall, 940 subjects (age = 46.2 ± 13.4 years) were considered. Subjects (n = 778) using on-demand phosphodiesterase type 5 inhibitors (PDE5is) were designated "performers" (60%) without a formal ED diagnosis or "patients" with a medical diagnosis. Patients were older than performers, with more self-reported comorbidities; patients used a higher PDE5i dosage and purchased it from official pharmacies more often than performers did. Of avanafil users (n = 39), no differences in total IIEF or subdomain scores were observed after adjusting for confounders. However, avanafil users less often declared its use without an ED diagnosis and a physician prescription. Overall, the latter condition was associated with higher PDE5i-related satisfaction.

CONCLUSION

The survey shows 2 different attitudes toward ED and PDE5i use: for recreational use and without a medical prescription or with a formal diagnosis and medical prescription. Avanafil, a 2nd-generation PDE5i with a good balance between efficacy and tolerability profile, is more frequently prescribed by doctors than self-prescribed compared with other PDE5is. Because the major challenge is to decrease the high dropout of 1st-generation PDE5is, further studies will be needed to clarify this topic. Corona G, Maggi M, Jannini EA.
