When Did Viagra Come Out: The History

History of Viagra

The history witnessed cases when great scientific discoveries were made by chance. X-rays became the first such discovery at the end of the 19th century. The same thing happened with antibiotics – their properties were accidentally discovered by Alexander Fleming. The invention of Viagra turned out to be a very interesting story.

History of Viagra: discovered by accident

It all started in 1992 in the UK. The company Pfizer began conducting scientific experiments aimed at determining the effect of sildenafil citrate on the heart muscle. This substance is a type of phosphodiesterase selective inhibitor. Scientists believed that it would increase blood flow to the heart and thereby reduce blood pressure. That is, initially sildenafil was supposed to treat diseases of the cardiovascular system.

The study involved a group of men who were given sildenafil tablets. However, the result was disappointing: it did not affect the level of pressure or the blood circulation in the heart. It seemed that all the efforts of scientists ended in nothing. But it was noticed that many participants in the experiment refused to return the pills given to them. And some even asked to give them more Sildenafil.

When experts from Pfizer asked “Why do you still need pills?”, the participants admitted that they had an erection after using them.

This unusual fact interested scientists. In 1993, they began to conduct another study, during which it was proved that the use of sildenafil really improved an erection. Pfizer realized that this drug could make a lot of money and initiated huge research that lasted for 3 years. They conducted the most detailed studies of sildenafil, during which all properties of the substance were revealed. Finally, in 1996, a new medicine appeared – Viagra. This was the year of Viagra invention.

Its name was formed by combining 2 words – “Vigor” (which means “power”) and “Niagara” (the largest waterfall in North America). In the same year, Viagra was patented. Thus, its main ingredient, sildenafil citrate, enhances the blood flow into the male sexual organ and thereby increases the effect of nitric oxide on the cavernous bodies. This results in an erection.

March 27, 1998 is a significant event in the world of pharmaceuticals. On this day, the Department of Medicines (USA) approved Viagra for sale. Its effectiveness was so high that in 1998 the income from the sale of a new drug for the treatment of erectile dysfunction amounted to about $1 billion (the drug cost $10 at the pharmacy). In the same year, the inventors of Viagra F. Murad, R. Ferchgott and L. Ignarro received the Nobel Prize for the invention of Viagra. Officially, it sounded like “for discovering the role of nitric oxide in regulating the activity of the cardiovascular system”. All experts unanimously recognized that Viagra is a brand new drug for treating weak erections.

Today, there are many other drugs used to treat erectile dysfunction. The richest assortment is presented in Cheap RX. Now you can even buy generic Viagra that has the same mechanism of action but is much cheaper.

How did men treat impotence before Viagra was invented?

People have always been interested in drugs to stimulate potency. Before Viagra was invented, potency was increased with the use of drugs that were injected into the genital organ with the help of injections or through a catheter. Unlike blue pills, they caused an erection immediately and men often felt uncomfortable: the man had to start having sex immediately. Viagra simplified the use of products for potency. The drug became a real revolution in the world of goods for intimate services.
