Erectile Dysfunction Clinical Trial
Official title:
Oral Administration of L-Arginine in Patients With Erectile Dysfunction
The purpose of the study is to determine whether the treatment with L-arginine leads to an improvement of erectile dysfunction in patients with erectile dysfunction.
Erectile dysfunction (ED) is a common medical disorder often affecting the aging male.
Nitric oxide (NO) is a physiological signal essential to penile erection. NO synthase (NOS)
catalyzes the production of NO from L-arginine. ADMA, a competitive inhibitor of NO synthase
increases with age and many disorders that reduce NO in the erectile tissue are commonly
associated with ED. Although new pharmacological strategies have been identified for medical
treatment of ED, patients often seek alternative therapies for cost or side effect reasons.
The aim of the present study is to determine the efficacy of orally administered L-arginine
on ED not caused by established organic disease.
