Why is Viagra prescribed for?

Viagra 100 Pills contain Sildenafil which belongs to a group called phosphodiesterase type 5 inhibitors. So used to treat adult men with erectile dysfunction known as impotence. Sildenafil acts by enhancing NO action and inhibiting PDE-5 in the penis. The mechanism of erection of the penis involves the release of nitric oxide during sexual stimulation. Nitric Oxide activates the enzyme guanylate cyclase which results in increased levels of cyclic guanosine monophosphate. It works by helping to relax the blood vessels in the penis and allow the blood to flow into the penis when you get sexually excited. Erectile dysfunction is inability of men to maintain an erect penis with sufficient rigidity to allow sexual intercourse.

How does Viagra Work?

Viagra 100 works by binding to an enzyme called phosphodiesterase. This enzyme prevents it from converting the chemical cyclic guanosine monophosphate into guanosine triphosphate. When a person becomes aroused the brain sends a signal to the cells in the penis to release nitric oxide that turns on the production of cGMP. Thus, it allows more blood to flow into the penis. There is no cGMP build-up and no erection without the stimulation to produce nitric oxide. This drug should not be given to patients with an erection without sexual stimulation. The effect of a build-up in cGMP is the relaxing of artery walls making the arteries bigger.

How can we take this medicine?
