How does it work?

Viagra tablets contain the active ingredient sildenafil, that is a drugs utilized in the treatment of erectile dysfunction (impotence). Sildenafil is additionally obtainable while not a complete name, ie as the generic medication.

Sildenafil is named a phosphodiesterase type five inhibitor, and works by preventing the action of a chemical within the body called phosphodiesterase sort 5.

An erection is created via a complicated chain of events, involving signals from the nervous system and the release of chemical messengers at intervals the tissues of the penis. One of these chemical messengers is called cyclic GMP.

Cyclic GMP causes the blood vessels in the penis to widen by relaxing a skinny layer of muscle found in the blood vessel walls. This permits more blood to enter the penis, that ultimately leads to the penis changing into rigid and erect.

Cyclic GMP is often lessened by another chemical within the body called phosphodiesterase kind five. Sildenafil works by preventing the action of phosphodiesterase sort 5, so stopping the breakdown of cyclic GMP. This suggests that that the blood vessels are kept dilated for longer, improving blood flow to the penis and maintaining an erection.

As sildenafil enhances the actions of the chemical messengers accountable for producing an erection, it will only work once these messengers are present. This suggests that that sexual stimulation is required for it to produce and maintain an erection. The dose ought to be taken approximately one hour before you propose to own sex
