How Viagra Works

Male impotence drugs are finally getting the respect they deserve. When Viagra tablets first came out, they were immensely popular, but they were also the butt of many jokes. The jokes have now all but stopped, as people realize how vital these pills are to men who struggle with impotence.

Though there are differences between Viagra, Cialis, and Levitra, they all work in the same way. All these male impotence drugs have the ability to block an enzyme, namely PDE-5. This enzyme can reduce blood flow to the penis. When it's blocked, penile blood flow is restored.

Despite the fact that all three drugs work in the same way, they affect people differently. As any Viagra seller will tell you, Viagra has been around the longest of the three, and is therefore the most tried and true option. Some men, however, prefer Cialis, since it has a larger window of effectiveness.

In general, the prices of the three drugs are very similar. However, no matter what prices you see at your pharmacy, they are rarely the lowest prices available. You'll find much lower prices on these drugs when you shop online, and you get the added benefit of having them delivered.
