Some of the best inventions and discoveries in the history of civilization have been accidental. Penicillin, Teflon, radioactivity, even your favourite Coca-Cola were all chance discoveries. An accidental invention is one where scientists are trying to find a solution to problem A but chance upon a solution to problem B. This is exactly what happened in the case of mankind's dearly loved drug Viagra, that treats erectile dysfunction. In 1989, chemists at Pfizer's research centre in Kent, England, were working to find a new drug to treat hypertension and angina pectoris (chest pain due to blocked arteries). A new compound that was named Sildenafil (UK92480) was created and subsequently tested on a group of men. Unfortunately, in the clinical trials, the compound failed to have a desired effect on hypertension and did not help in dilating the muscles in the heart. In 1953 Dr Norm Larsen, founder of the Rocket Chemical Company, was trying to create a fluid which would prevent nuclear missiles from going rusty. There’s lots of waiting around in a Cold War, and the US government found that their arsenal wasn’t faring well. A group of scientists working at Pfizer's lab in Kent developed a drug called Sildenafil for the treatment of angina. Clinical trials in Swansea found that it had almost no effect on the heart or angina, but quite a pronounced side effect on another organ. Cue a quick brainstorming session by the marketing department, and Viagra soon went on sale across the globe. In 2008, the peak sales year for the drug, Pfizer sold almost $2bn worth of the stuff. The patent has now expired in much of Europe, allowing rival companies to sell their own versions.
