Viagra (sildenafil) Treatment for Erectile Dysfunction

Viagra (sildenafil) anti-ED Medication

Viagra (sildenafil) is an oral medication used to treat erectile dysfunction, a disease when a man is unable to maintain or keep erection firm enough to have sex. Viagra is known as phosphodiesterase-5 (PDE-5) inhibitors, which boost natural signals that take place during sexual stimulation, thus causing and prolonging erection.

Erection itself is a complex process involving special brain impulses, nerves and blood vessels in your penis, and a male sex hormone testosterone. During sexual stimulation your body produces nitric oxide - a special substance which widens and openes blood vessels in your penis, thereby maintaining erection. Viagra increases blood level of nitric oxide, thereby helping to relax blood vessels and increase a blood flow into your penis.
