How does viagra help to maintain an erection?

Viagra is an unbeaten drug to stimulate an erection. It comes in tablets forms. So it is very easy to use and never causes pain while using it unlike other impotence treatment injections.

When it is taken, it releases what is called sildenafil citrate. This is the compound which helps in supporting a lasting erection in men suffering from erectile dysfunction. The sildenafil citrate flows throughout the body; its main working area is the penis. It controls an enzyme phosphodiesterase 5 in the penis. By doing so, this drug enables to maintain an erection that is produced when the penis is stroked.

This enzyme belongs to 11 types of phosphodiesterase. Viagra target PDE5 alone that help in maintaining an erection. PDE5 takes what is called cGMP and breaks it down so that is unusable. The work of CGMP is to relax the smooth muscle in the arterial walls of the penis. When CGMP relaxes these smooth muscles, blood vessels in the penis flood with blood and start to expand the length and girth of the penis causing an erection).

When a man gets sexually stimulated, the brain sends a message to special NANC cells in his penis. These cells then create nitric oxide in the penis. This process produces a chemical called cyclic GMP consecutively.

This chemical forces the blood to flow inside the penis. Viagra stops an enzyme that impedes cyclic GMP, thus it allows more cyclic GMP to increase and sustain an erection. The raise in cyclic GMP expands the arteries and narrowing of the veins, which means the penis remains hard and flushed with blood.

Men with impotence lose a considerably excess of cGMP by the PDE5 enzyme. So it decreases blood flow into the penis. The sildenafil citrate produced by Viagra, but, blocks the holes in the PDE5 instead of cGMP. This means that the enzyme will be busy crashing sildenafil citrate instead. As a result more cGMP will be produced and thus blood flow will be increased in the penis.

The erection will be continued as long as the sildenafil citrate is there in the body. In general it continues about four hours in the majority of individuals. In few people, however, it could last longer. It has been reported in rare cases where men need to check with doctor to throw away their erection. It does not always take place. But it is essential to check with your doctor to make sure Viagra is a drug can be right for you.

According to laboratory tests, Viagra takes as little as 14 minutes to work. When a 100 ml tablet taken 2 hours was administered after food consumption, study participants all noted an erection within a 14- to 30-minute period. Viagra can last for up to 4 hours. So the role of this drug can’t be ignored in increasing stamina and recharge sexual performance in the bedroom.
