Understanding Impotence and Viagra

Impotence is a common penile issue more commonly known as erectile dysfunction. According to the National Institute of Health, 30% of the male population has experienced problems in sustaining an adequate erection.

There can be many reasons for impotence, varying from chronic health issues to short term drug induced states. If you are concerned about your penile issues then you should contact you doctor. In many cases, General Practitioners tend to prescribe oral medication drugs such as Viagra. This drug can be called many other names, such as Sildenafil citrate or Revatio and is used to treat impotence and pulmonary arterial hypertension (PAH).

Viagra was originally developed and manufactured for the treatment of Angina, but studies showed that it had very little effect on its primary goal. Instead, experts noticed that it regulated the blood flow of the penis, helping men obtain erections. Since it became available in 1998, Viagra has been the main treatment for erectile problems and has helped millions of men around the world.

How does Viagra work?

Viagra is the most common impotence medication in men with erectile dysfunction. It works by stopping a specific enzyme from working. Cyclic GMP is released when the male feels sexually aroused, and this causes the blood to flow quickly into the penis, making it erect. An enzyme called PDE5 is released due in time to degrade the cyclic GMP and to bring the penis back to its normal state. Viagra simply blocks the PDE5 from working, therefore creating a sustainable erection.

Viagra uses this specific method because the body uses at least 11 different kinds of PDE, and only one of them is found in the penis: PDE5. This means that the effect of Viagra is limited to the penis only, making chances of heart attacks and other issues a problem of the past!

Impotence no longer needs to be a cause for embarrassment or stress. With the modern advances in the pharmaceutical industries drugs such as Viagra can now be a common form of treatment, acting within 30 minutes from digestion and lasting up to four hours!
