Can Viagra, Levitra, Cialis really solve the problem of ED?

Sildenafil, widely known as Viagra, is the main drug used to treat ED. It is one of the most popular drugs for treating erectile dysfunction by increasing the capability for blood flow to the penis. Recently, new "impotence drugs" called Cialis and Levitra have been announced.
All three of these drugs are known as "PDE5 inhibitors." How does a PDE5 inhibitor work?

The brain responds to sexual stimulation by sending out nerve signals. These signals cause the release of a chemical called nitric oxide, which relaxes muscles in the penis so that more blood can flow in and the veins which normally carry the blood away from the penis can be compressed. So that more blood flows in and less blood flows out. This makes the penis hard and erect

The body also contains an enzyme called PDE5, which reduces the effect of nitric oxide in producing an erection. A PDE5 inhibitor limits the release of nitric oxide, which temporarily restores the body's natural sexual response.

These drugs are unique because they only work when a man is sexually stimulated. Sexual stimulation is necessary for these drugs to help cause an erection.

Viagra works best when taken on an empty stomach about an hour before attempting an erection.

Cialis can be taken without regard to food. It should be taken prior to sexual activity.

Levitra stays effective for 5 - 6 hours and that the drug can take effect in as few as 15 minutes, but takes about 25 minutes for most men. Levitra can be taken with or without food, but preferably not after a heavy or high-fat meal, as this may delay the effect.

The above mentioned drugs for impotence like Viagra, cialis and levitra can definitely give a respite to a man suffering with ED(erectile dysfunction). But the drawback is, you have to take these drugs at least an hour in advance to have proper erection. That means you have to plan your sexual intercourse and then proceed and definitely takes away the spontaneous romanticism from the love life. Moreover all these drugs have some or the other side effects like sweating, flushing, upset stomach, stuffy nose etc.
