简要总结
This study aims to compare the Clinical Efficacy, Safety, and Tolerability of L-Arginine + Fenugreek, Tadalafil + L-Arginine + Fenugreek, and Tadalafil + Testosterone in the Treatment of Erectile Dysfunction in Elderly Diabetic Patients. The primary objective is to compare the clinical efficacy of L-Arginine + Fenugreek, Tadalafil + L-Arginine + Fenugreek, and Tadalafil + Testosterone in improvement of IIEF-5 score in elderly diabetic patients with erectile dysfunction.
The secondary objective is to compare the safety and tolerability of L-Arginine + Fenugreek, Tadalafil + L-Arginine + Fenugreek, and Tadalafil + Testosterone in elderly diabetic patients with erectile dysfunction. The study is designed as a prospective, Interventional, Randomized, Open-label, Parallel Group, Comparative, Multicentric. The study population consist of patients in the age group of ≥50 years diagnosed with elderly diabetic patients with erectile dysfunction.
The study visit will be as per the following schedule:
Visit 1 (Day 0): Screening, Randomization, Enrollment, Baseline assessment, and Treatment initiation
Visit 2 [Day 28 (4 weeks) ± 7 days]: Follow-up visit
Visit 3 [Day 56 (8 weeks) ± 7 days]: Follow-up visit
Visit 4 [Day 84 (12 weeks) ± 7 days]: 48 hrs after end of treatment; End-of-study visit
Unscheduled visit: As required (during study participation)
