Viagra Day is an American observance dedicated to the creation of Viagra, a medication used to treat erectile dysfunction. The drug has helped millions of men restore erectile function and improve quality of life. Viagra should only be used as prescribed by a doctor. The holiday is observed every year on March 27.
History
Viagra Day is connected with the history of the development of sildenafil citrate, the active substance in Viagra. Work on the drug began in 1989 at the British division of Pfizer. Scientists Peter Dunn and Albert Wood were initially developing a medication intended to treat hypertension and angina.
During clinical trials, sildenafil did not show the expected effectiveness for heart conditions. However, participants reported a notable side effect in the form of improved erections. Researchers shifted the focus of testing, and the drug was reclassified as a treatment for erectile dysfunction.
In 1996, Pfizer received a patent for sildenafil citrate. In 1998, the drug was approved by U.S. health authorities and entered the pharmaceutical market. Viagra quickly became one of the most successful prescription medications in history. Despite the appearance of many generic alternatives, the original brand remains widely recognized.
Interesting Facts
- Viagra became one of the fastest approved prescription drugs. While many medications undergo testing for five years or more, Viagra completed the process in about two years.
- Annual global sales of Viagra have exceeded one billion dollars.
- The drug works by improving blood flow through vasodilation and does not directly affect the brain or nervous system.
