- Sildenafil, which is the generic name of Viagra was developed by Pfizer pharmaceuticals in 1998. Originally the drug was researched as a treatment for hypertension. Further in its development it was shown to increase blood flow to the penis, which results in erection. The brand name Viagra lost its patent in 2000, and it is now marketed by several companies under the generic name, Sildenfil. Peter Dunn and Albert Wood are credited with the discovery, and Pfizer states that the company itself is the creator of the drug.
- Sildenafil works by increasing blood flow to the genital area of men. It works by opening blood vessels in the penis which allows blood to enter the penis and cause an erection. Sildenafil has become the most common way to treat the symptoms of erectile dysfunction, and it is now used by millions of men around the world. By opening the blood vessels, it has given relief and an improved sex life to these men.
- While Sildenafil is very effective for erectile dysfunction and provides relief to its users, it is not a cure. Many people believe that Sildenafil completely resolves the problem. However, in many cases there is a underlying condition present that should be addressed before using the drug. Erectile dysfunction can be caused by serious medical conditions and your doctor should try to identify these causes before prescribing the drug. Another common misconception is that it works for everyone. While it does alleviate the symptoms of most of its users, it is not a cure all for everyone. If Sildenafil does not work, your doctor may prescribe other medications.
- Although Sildenafil has been shown to be a relatively safe drug, there are reported side effects that you should consider before starting drug treatment. One of the them concerns vision, including blurred vision, reduced night vision and a blue tint associated with vision. Sildenafil also commonly causes nasal congestion and headaches. The most dangerous but rare side effect is priapism. Priapism means causing an erection that lasts longer than 3 hours. This can be an extremely dangerous effect of the drug and if experienced, the user should immediately seek medical attention.
- Sildenafil has given many men a second chance at a fulfilling sex life and has improved the marriages of many couples. It is generally safe to use and has become the best way to treat the symptoms of erectile dysfunction. Sometimes referred to as "the little blue pill," it has become the buzz word for the treatment of impotence.
