How does generic viagra works?

aphrodisiac, it works only when a man is sexually stimulated.
When a man is sexually excited, the penis will fill with enough blood
to cause an erection. Generic Viagra works by increasing blood flow to
the penis, as well as causing penile muscles to relax. It does not,
however, initiate an erection. This is a common misconception that has
led to widespread disappointment. Scientists have found that in men
suffering from erectile dysfunction, an enzyme constricts blood flow to
the penis. This enzyme is called phosphodiesterase type 5 (PDE5).
Generic Viagra stores blood flow in an already-stimulated penis by
inhibiting the action of this enzyme.
By inhibiting PDE5, smooth muscle in the penis remains relaxed for a
longer period. This allows for increased blood flow into the cavernous
tissue of the penis thereby generating an erection. Sexual stimulation
is still required to get an erection, but often times, less than would
be normally required. Viagrax-DS enables many men with ED to respond to
sexual stimulation. When a man is sexually aroused, the arteries in the
penis relax and widen, allowing more blood to flow into the penis. As
the arteries in the penis expand and harden, the veins that normally
carry blood away from the penis become compressed, restricting the
blood flow out of the penis.With more blood flowing in and less flowing
out, the penis enlarges, resulting in an erection.
