There are only three oral drugs approved by the FDA to treat Erectile Dysfunction: Cialis, Levitra, and Viagra. There are NO GENERIC versions of these drugs either. All work by increasing the flow of blood into the penis so that when a man is sexually stimulated he can get a strong and long lasting erection.
How Does Cialis, Levitra and Viagra Work?
All of the ED drugs, such as Viagra, work by blocking PDE5. When PDE5 is blocked, more of the chemicals that give you an erection remain, so the muscles in the penis do not tighten. This allows blood to stay in the penis longer, which allows you to maintain an erection longer.
Do They Work Without Stimulation?
Many men wonder if Cialis, Levitra and Viagra work without any stimulation. The answer to this question is NO. This is because the chemicals that cause an erection need to be released into the penis and these chemicals are released only when a person is aroused. Drugs such as Viagra have no effect on the release of these chemicals. It only keeps the chemicals working in the penis longer.
What Are the Differences Between Cialis, Levitra, and Viagra?
Cialis, Levitra, and Viagra work by a similar mechanism to cause erections. There are subtle differences in how long the drug works and how quickly it works. Levitra works a little longer than Viagra. They both take effect in about 30 minutes. With Levitra, the effects last for about 5 hours. With Viagra, the effects last approximately 4 hours. Cialis works a bit faster (within about 15 minutes), and lasts much longer -- up to 36 hours in some cases.

Understanding Erections and Erectile Dysfunction
When a man is aroused, nerve signals are sent from the brain and around the penis. These signals cause chemicals that relax the muscles in the penis. Normally, these muscles are tight or constricted so that blood cannot flow into the penis. When these muscles are relaxed or opened up, large amounts of blood are able to enter the penis, causing an erection. ED drugs such as Viagra help to increase the blood flow to the penis. An erection is stopped by another chemical (known as phosphodiesterase type 5 [PDE5]) which breaks down the erection chemicals that caused the muscles to relax in the first place. This causes the muscles in the penis to tighten, which causes the blood to leave the penis and stop the erection.
