Most of the great health discoveries related to drugs occurred unintentionally, by mistake, or by accident. Much like the discovery of penicillin, it also happened with Viagra, which was discovered by accident in March 1998, and revolutionized the sexual life of many men.

What is Viagra?

According to Wikipedia, "Sildenafil, sold under the brand names Viagra, Revatio, and others, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension."

It was initially developed by British scientists and later brought to market by the pharmaceutical company Pfizer. The pharmaceutical company Pfizer was looking for a drug that aimed to improve blood circulation in people suffering from angina pectoris, a disorder in the heart system that affects the blood vessels of the heart, causing them not to pump enough blood and therefore affecting the extremities and the rest of the body.

History

By 1986, Nitric Oxide's ability to help dilate blood vessels and facilitate increased blood flow was discovered.

The first clinical trials for the development of Sildenafil as a treatment for angina pectoris, in which the drug was administered to healthy volunteers, began in 1991. The results were disastrous, and Pfizer was on the verge of terminating the project.

The side effects surprised the researchers when some of the volunteers reported altered perception of color, headache, and penile erection.

In 1993, the first clinical trials were designed for the pharmacological development of Sildenafil as a treatment for erectile dysfunction. The drug proved to be successful in 21 independent practices.

In 1998, the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) approved its use as Viagra.

The tremendous commercial success of Viagra was evident when sales reached one billion dollars in the first year, reflecting the immense impact that this drug had and has on society.

In the United States alone, about 30 million suffer from problems with erectile dysfunction. Within the first two weeks of commercialization, 150,000 prescriptions were prescribed.

The success of the blue pill was so great that even former senator Bob Dole and Brazilian star Pelé were hired for the drug's advertising campaign.

Pfizer enjoyed the profits of its flagship product for several years; however, in 2003, two competitors appeared: Levitra, from Bayer; and Cialis, from Lilly and Icos.

Both began to erode Pfizer's collection capacity. In 2013 Pfizer's patent expired, and from that moment on, Viagra could be created by other pharmaceutical companies in an accessible form and under the generic name of "Viagra."

Are you suffering from erectile dysfunction?

There is no shame in admitting this condition. Many men suffer from this all over the world with no guidance. If your problem is psychological, using Viagra might only help you with the erection, but the problem might not get solved. Therefore, it is recommended to ascertain the cause of the situation after a thorough medical and psychological assessment.
