This has been one of the most tested of all drugs on the market. With something as important as sexual performance, the regulatory authorities around the world have demanded high levels of proof that the drugs on the market are as effective, yet as safe, as possible. As a result, there are more than one hundred clinical trials reviewing every possible feature of the drug and testing whether there are other applications. Under a different brand name, viagra is now sold for the treatment of pulmonary arterial hypertension, a problem in the arteries in the chest and lungs. Its use in cases of diabetes and following radical surgery for the removal of growths in the prostate has also been refined. Overall, more is now known about the biology of sexual activity than at any time in the past and levels of skill in improving sexual performance are at the highest possible levels.
One of the most important discoveries has been the link between erectile dysfunction and heart disease. There is now clear and compelling evidence that the onset of erectile dysfunction is a first potential symptom of heart disease. Thus, you should not self-medicate. You could simply go online and buy cheap viagra as a treatment for the immediate problem. But this ignores the longer term threat. You should always have a full health check-up before starting treatment with viagra. If no heart disease is detected, you can enjoy sex all the more. But if early symptoms of heart disease are detected, there are effective treatments to prevent the onset of cardiovascular problems. You can then enjoy sex with the peace of mind in knowing your life has been preserved and extended.
