Generic Viagra for impotence is one of the three oral treatments for impotence (male erectile dysfunction) available today. Generic Viagra capsules contain sildenafil as an active ingredient.
How does Generic Viagra work?
Generic Viagra works by blocking an enzyme called phosphodiesterase (PDE5). By inhibiting PDE5, the blood vessels of the penis remain relaxed for longer allowing an increase in blood flow. It also causes blood to be trapped in the penis helping to produce longer lasting erections. Viagra and the other treatments, Cialis and Levitra, only work in response to sexual stimulation.

It can be extremely effective. It has been shown to work in 78% of men regardless of the causes of their erectile dysfunction. In the case of men suffering from hypertension, it works in 70% of patients, and in those undergoing treatment for diabetes, the success rate is 57%.
Brand Viagra vs. Generic Viagra
Generic Viagra has the same active ingredient (sildenafil) as the brand Viagra, and its effect, potency and dose is equivalent.
While Viagra’s ability to improve erection was discovered as a side effect during the development of a heart treatment, Cialis and Levitra were developed specifically as drugs for erectile dysfunction and are, therefore, more refined treatments.
