Viagra, Viagra Pharmacological Properties
Sildenafil citrate was initially created as a drug to treat high blood pressure and angina. It was discovered that the drug had little consistent impact in this area, but that it did result in erectile activity. Viagra is the best known brand name of this drug, and it has been freely available in the UK and US since the 1990s.

Viagra works by replacing the body's cGMP with itself, and leading to a smoother muscle relaxation in the arteries of the penis. The cGMP is naturally produced during the physiological process of erection, therefore when the 'cGMP system' is not activated (i.e. there is no sexual stimulation) Viagra will not cause the user to develop an erection.
Viagra is available in a variety of doses to suit the different severities of impotence, and these are usually 25, 50 or 100 milligram capsules. The drug is available on the NHS in the UK and is recommended by US Medicare, and is widely available with little to no prior medical consultation on the Internet. There are also numerous herbal erectile dysfunction treatments now known as 'herbal Viagra'.
Between 1999 and 2001, Pfizer made $1 billion from sales of Viagra and the lives and relationships of millions of men were changed for the better.
