Brand Viagra

The primary indication of Generic Viagra is treatment of impotence. Its use is now standard treatment for impotence in all settings.

People on antidepressants may experience sexual dysfunction, either as a result of their illness or as a result of their treatment. A 2003 study showed that Brand Viagra improved sexual function in men in this situation. Following up to earlier reports from 1999, the same researchers found that Sildenafil was able to improve sexual function in female patients on antidepressants as well.

As well as erectile dysfunction, Sildenafil Citrate is also effective in the rare disease PAH. It relaxes the arterial wall, leading to decreased pulmonary arterial resistance and pressure. This, in turn, reduces the workload of the right ventricle of the heart and improves symptoms of right-sided heart failure. Because PDE-5 is primarily distributed within the arterial wall smooth muscle of the lungs and penis, Sildenafil acts selectively in both these areas without inducing vasodilation in other areas of the body. Pfizer submitted an additional registration for Generic Viagra to the FDA, and Sildenafil Citrate was approved for this indication in June 2005. The preparation is named Revatio, to avoid confusion with Viagra, and the 20 milligram tabs are white and round. Brand Viagra joins bosentan and prostacyclin-based therapies for this condition.
