Undoubtedly, Viagra has taken the world of medicine by a storm; this drug has become the most sought after drug over the past few years and has become the harbinger of new youth for men suffering from Erectile Dysfunction.  The main component of this medicine is Sildenafil Citrate, which is a PDE5 inhibitor.

This drug fights the condition of Erectile Dysfunction at the grass root level, but before knowing that we must first understand what the cause behind a penile erection is. Whenever there is some kind of sexual stimulation the brain orders the arteries within the penis to dilate, the dilation of the arteries causes the smooth muscles of the penis to relax and as a result, the male organ becomes hard and erect. As men get older, their arteries become less flexible so they cannot dilate anymore, as a result the person cannot achieve or sustain an erection long enough.
