The History of Viagra
In 1989, two British Pfizer scientists Albert Wood and Peter Dunn created a drug known as sildenafil citrate. They believed that the drug would be helpful in the treatment of high blood pressure and angina. This is a chest pain that comes hand in hand with coronary heart disease.
In 1990, several trials were made on the drug with the hopes that it would be used for heart problem treatment. However, the volunteers who used the drug in the clinical trials reported an increase in erections few days after using the drug. This was according to researcher Ian Osterloh.
This discovery that the drug could cause an erection was an unplanned event. Pfizer realized that erectile dysfunction was an unmet medical issue and realized that this was a great financial opportunity.
Nicholas Terret was named in 1991 as one of the users of Sildenafil for heart problems treatment, and he is therefore known as the father of Viagra since he discovered just how much use the drug would be for the treatment of erectile dysfunction.
In 1994, Terret and his colleague Peter Ellis discovered that the drug enhanced blood flow to the penile region for those patients that suffered from ED as they investigated the utility of the drug as a heart medicine.
The drug was discovered that it had the ability to enhance muscle relaxation effects of nitric oxide, which is the chemical that is released when an individual is sexually stimulated. This relaxation increases blood flow and assists in the production of an erection.
FDA approved the patent name Viagra as the name of the blue pill for the treatment of ED in 1998. From then, Viagra is now the world’s favorite little blue pill that has revolutionized erectile dysfunction’s treatment. It has improved many men’s sex life and given a new ray of hopes to those suffering from erection problems. However, the pill does not work if one is not sexually stimulated.
