Daily Oral L-arginine Plus Tadalafil in Diabetic Patients With Erectile Dysfunction

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.

oral daily tadalafil 10mg for 8 weeks

serum testosterone level

Diagnostic Test

measurement of serum testosterone level

HBA1C

Diagnostic Test

measurement of HbA1C levels

penile doppler

Device

penile doppler to measure the degree of erection and penile vasculature

Primary outcomes

  1. 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.

    Time frame: 8 weeks of treatment

    Efficacy 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).

  2. Increase in Serum Total testosterone level in (nmol/L) after treatment.

    Time frame: 8 weeks of treatment

    Measurement of total testosterone level in (nmol/L) improvement after treatment

  3. 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.

    Time frame: 8 weeks of treatment

    Measurement of penile doppler parameters improvement after treatment peak systolic velocity in (cm/sec), end diastolic volume in (cm/sec) and resistive index (RI).
