How does it work?
Viagra tablets contain the active ingredient sildenafil, which is a medicine utilized in the treatment of erectile dysfunction (impotence). Sildenafil is also available without a complete name, ie because the generic medication.
Sildenafil is called a phosphodiesterase sort 5 inhibitor, and works by preventing the action of a chemical within the body called phosphodiesterase kind five.
An erection is created via a complicated chain of events, involving signals from the nervous system and the release of chemical messengers among the tissues of the penis. One of those chemical messengers is named cyclic GMP.
Cyclic GMP causes the blood vessels in the penis to widen by relaxing a thin layer of muscle found in the blood vessel walls. This permits more blood to enter the penis, which ultimately leads to the penis turning into rigid and erect.
Cyclic GMP is normally dampened by another chemical within the body referred to as phosphodiesterase sort five. Sildenafil works by preventing the action of phosphodiesterase sort 5, therefore 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 can solely work once these messengers are gift. This means that sexual stimulation is required for it to produce and maintain an erection. The dose should be taken approximately one hour before you plan to own sex
