Daily Oral L-arginine Plus Tadalafil in Diabetic Patients With Erectile Dysfunction: A Double-blinded Randomized Controlled Clinical Trial

ClinicalTrials.gov · COMPLETED, 2018

108 participants

Abstract

Tadalafil is an effective oral therapy in erectile dysfunction. L-arginine is a pro drug that increase the level of nitrous oxide in the smooth muscles so can increase the strength and duration of erection. this clinical trials compare the daily oral L-arginine plus tadalafil in treatment of erectile dysfunction in diabetic patients.

Conditions: Erectile Dysfunction.

Primary outcome: International Index of Erectile Function score (IIEF-5) improvement after treatment. IIEF-5 score of 22-25: No erectile dysfunction (ED), 17-21: Mild ED, 12-16: Mild to moderate ED, 8-11: Moderate ED, 5-7: Severe ED.; Increase in Serum Total testosterone level in (nmol/L) after treatment.; Improvement in Penile Doppler parameters after treatment including peak systolic velocity in (cm/sec), end diastolic volume in (cm/sec) and resistive index (RI) that = (peak systolic velocity - end diastolic velocity ) / peak systolic velocity..

Enrollment: 108 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 108 participants or records.
