Viagra is a drug whose main function is to cure erectile dysfunctions. Besides treating this dysfunction, Viagra is also used to treat pulmonary arterial hypertension (PAH) condition as well as altitude sickness. Sportswomen and sportsmen also use Viagra as a stamina enhancer. Viagra is known to expand the blood vessels and thereby supply more oxygen to body parts leading to increased strength and stamina.
How Viagra Functions
Viagra works by inhibiting an enzyme called GMP that modulates the flow of blood to the male private parts during an erection. Through this inhibition, the unregulated blood flow to the penis leads to increased strength for maintaining an erection.
History of the Drug
Viagra started production in 1998 and Viagra has since then become a leading brand name for erectile dysfunction. Cialis is a more recent competition to Viagra having been approved by the US Food and Drug Association (FDA) in 2001. However, Cialis online marketing has not had a successful impact on the dominance of Viagra online. The Viagra drug was first produced in the United Kingdom Kent laboratories of Pfizer pharmaceuticals by a group of research chemists with the company. It was originally produced and tested for the medical cure of pulmonary arterial hypertension (PAH) and other hypertension conditions. The first tests on the effectiveness of this drug were carried out in Morriston Hospital in Swansea.
According to the initial test findings as explained by Ian Osterloh, the chemist in charge of the testing, the drug showed low effectiveness in treating the designated diseases but instead, it resulted in extensively inducing a penile erection. Consequently, Pfizer decided to market the drug as an erectile dysfunctional drug as opposed to medication for the other diseases originally thought to be treated by the drug. In March 1998, Pfizer was given a go ahead by Food and Drug Association (FDA) in the United States to sell the product as an erectile dysfunction medication. It became the first oral medication to threat this medical condition. The success of Pfizer with this new drug was remarkable. Between 1999 and 2001, the company made sales exceeding $1 billion. This was a record for a new drug in the market and the sale of Viagra online has continued to sore year after year.
