Viagra has become one of the most popular drugs in the USA. It is used to treat erectile dysfunction: the inability of some men to get or maintain an erect penis. The European Medicines Evaluation Agency will have to give its consent before the drug can go on sale in Britain, but Pfizer Inc - the company that manufactures the drug - hope to get this approval by the autumn.
How does Viagra work?
Viagra, also known as Sildenafil, does not directly give a man an erection. It works by boosting the natural mechanism that leads to an erection. When a man is sexually aroused, certain tissues in his penis relax. This allows large amounts of blood to flow into the muscle, thus producing an erection. Viagra helps by elevating the levels of the chemical that causes the tissues to relax. These effects were discovered accidentally. The drug was originally developed to improve blood supply to the heart in angina sufferers.
