How does Viagra work
Viagra Brand is a medication which was specially created to help
millions of men all over the world to fight against such an
unpleasant sexual disease as an erectile disorder, which means the
repeated inability to get or maintain an erection that is not long
and firm enough for sex. Viagra is very powerful at treating
erectile dysfunction because it causes more blood coming to penis.
In order to understand how Viagra works you should understand the
process of erection itself. When a man is sexually stimulated, his
penis's arteries widen and relax. This helps blood to flow into the
tissues. Consequently these arteries harden. In a word Viagra helps
the penis fill with enough blood and remain this blood in the
erectile tissues to cause a successful erection. If to be more
precise Viagra works by blocking PDE5 (the degrading action of
phosphodiesterase). When PDE5 is blocked, more of the chemicals
responsible for the erection remain, making muscles in the penis do
not constrict. Brand Viagra helps blood to stay in the penis longer. This
allows blood to stay in the penis longer, which allows the patient
to get and maintain a successful erection. When sexual intercourse
is over erection goes away. Normally Viagra should not cause an
erection without sexual stimulation, because the chemicals that
cause an erection need to be released into the penis. This can
happen only during the stimulation.
How much time does it take to get a desirable result?
Many men are interested in this question. But the answer cannot be
the same for each man. It depends upon such factors as patient's
health condition and age. Generally Viagra begins to work in about
15 minutes after taking pills. However for some men Viagra becomes
active within 30 minutes.
How long will the erection last with Viagra?
Supposedly Viagra should be effective for at least four hours;
however the erection begins to decrease gradually after about two
hours.
