The Great Blue Pill aka Viagra has completed more than 19 years of existence and continues to be the beacon of hope for men suffering from impotence. The year 1989 is of great importance to such men as it marks the beginning of the era of Sildenafil citrate, a drug that British Pfizer scientists, Peter Dunn and Albert Wood, believed, could help to treat high blood pressure and angina, chest pain associated with coronary heart disease. Sildenafil citrate is more commonly known as Viagra.

The history of viagra

Then in 1991, Dr. Nicholas Terrett, a British scientist, also known as the father of Viagra gets mentioned in the patent for Viagra. This is followed by numerous trials of the drug to find its applicability related to heart diseases. During these trials volunteers reported increased erection for several days after taking the prescribed dose. An accident helped find the true applications of Sildenafil citrate. Pfizer patents sildenafil citrate in 1996 and gets it approved by the FDA for use in 1998.

Dr. Brian Klee, senior medical director at Pfizer told AFP the French News agency that originally they were testing sildenafil, the active drug in Viagra, as a drug that could lower blood pressure and treat cardiovascular problems. During these trials, most of the people did not return the medication back because it had the side effect of causing erection to be harder, firmer and log lasting.

It is still the benchmark to contend with

In 2011, Pfizer’s US patent for Viagra was extended by a federal judge to make sure generic brands cannot come into the market until 2019. One reason for this could be highly specialized field in which the drug operates and in order to maintain the high standards required for the production of the drug, such a step was undertaken.

Viagra has faced competition from various other drugs in the same segment, some of which are, Cialis, Stendra etc. Viagra for sale is available through many channels and can be obtained online as well In some countries, Viagra is being sold over the counter but on others prescriptions might be required.

According to a statistic, Viagra had been used by more than 35 million men within just 10 years of its launch. Although there are some side effects of the drug at the moment but considering the above statistic, one can only imagine the impact that it has been able to make in the market.
