How Viagra Works - Viagra 101
Viagra has been hailed by many men as the ‘Wonder Drug.’ And why not, it is the answer to their prayers: a sexually satisfying night with their beloved with a single pop of a pill. How does a single pill cure erectile dysfunction? How Viagra works, anyway?
Viagra’s chemical component, Sidenafil Citrate, works by inhibiting PDE-5, an enzyme that breaks down cGMP that is responsible for the dilation of arteries in the penis. When PDE-5 is blocked, more cGMP is retained in the body and the penile arteries smoothen out and dilate to accept the surge of blood that causes penile erection.
What makes Viagra special is that it works like a natural wonder. It is known that the primary cause of penile erection is surge of blood in dilated penile arteries. And surge of blood only happens when a man gets aroused. This means that Viagra will work only when a man gets aroused. The brain will send signal that it needs cGMP and Viagra will act accordingly by blocking PDE-5 that breaks down cGMP. This is the reason why Viagra needs to be taken 30 minutes before a planned intercourse so that it will work during arousal and the effect will be longer. Aside from penile erection, Viagra can also heighten sexual drive.
Viagra comes with side effects, too. However, with your physician’s close supervision, you’ll experience nothing serious side effects with Viagra. Just follow your doctor’s prescription and you won’t go wrong. And knowing how Viagra works and the medicines that works adversely with it, you’ll have a fulfilling sexual life without any worries.
