Brief summary

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.

Primary

MeasureTime frameDescription
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.8 weeks of treatmentEfficacy of oral L-arginine 5 g plus oral tadalafil 10 mg in treatment of erectile dysfunction in diabetic patients is evaluated by International Index of Erectile Function score (IIEF-5).
Increase in Serum Total testosterone level in (nmol/L) after treatment.8 weeks of treatmentMeasurement of total testosterone level in (nmol/L) improvement 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.8 weeks of treatmentMeasurement of penile doppler parameters improvement after treatment peak systolic velocity in (cm/sec), end diastolic volume in (cm/sec) and resistive index (RI).
