Viagra

Viagra is the trade name that the drug company Pfizer uses for the drug Sildenafil Citrate. Released by Pfizer in 1998 as a drug to help men with erectile dysfunction, Viagra’s usefulness in battling this condition made it an overnight success. So well did Viagra work for men who suffered from erectile dysfunction that by the following year there were very few people who had not heard of this wonder-drug.

Originally, Sildenafil Citrate was created for the treatment of angina – a condition that causes chest pains due to a lack of oxygen in the heart. It was supposed to help those who suffered from angina by increasing the blood flow, and subsequently the oxygen content, to the heart. Although preliminary tests showed that Sildenafil Citrate was not a promising drug for angina sufferers, Pfizer technicians discovered that male test subjects who suffered from erectile dysfunction were experiencing more and longer lasting erections when they took the drug. Pfizer patented the drug in 1996 and it was approved by the FDA for use in the treatment of erectile dysfunction in 1998. Pfizer immediately began marketing the drug under the name Viagra, and it became the first drug used for erectile dysfunction in the United States.

Although there have since been other drugs marketed for use in the treatment of erectile dysfunction, sales of Viagra are still impressive, and it remains a widely-prescribed drug in the United States and Europe.

It must be stated that not everyone can take Viagra, and that those considering taking it should consult their doctor first. Those who suffer from any type of heart, liver, or kidney conditions may not be able to use Viagra, although under a doctor’s care some may be able to use it in smaller-than-normal doses. Those who are taking Viagra should see their doctor on a regular basis to make sure that there are no adverse side effects that may put the patient’s health in jeopardy.
