Viagra
Viagra is an anti-impotence drug designed to help men overcome erectile dysfunction (ED). Originally developed by Pfizer Inc as a product to help angina sufferers, the drug is now widely recognised as the best way to beat impotence. It is generally available on prescription through the NHS and from on-line pharmaceutical resellers.
Viagra works by increasing blood flow to the penis. When taken the drug relaxes the tissues around and inside the penis. Blood vessels become less restricted so allow a greater volume of blood to enter the penis when a man becomes sexually aroused. This results is a firm erection, even in men who have previously found it difficult to obtain one.
The long-lasting effects of Viagra mean that men who have suffered from ED can sustain an erection long enough to have sexual intercourse. To date, over 16 million men suffering from ED have found Viagra works for them.
Viagra is known to be safe for all healthy men. Those with existing heart, liver or kidney conditions should avoid Viagra or seek medical advice before taking the drug. Certain side effects may be experienced when taking Viagra. They are non-life threatening but could include headache, blurred vision, sensitivity to light and facial flushing.
Recent studies also suggest that Viagra might improve female sexual arousal too. To find out more information on Viagra please use the resources on our site.
