Levitra, Cialis and Viagra are all PDE-5 inhibitors. The purpose of these are to assist in relaxing hard penile arteries which then let the blood flow into the penis, hence allowing an erection. All of these medications also assist in maintaining high levels of cGMP in the penis. In the event that you don’t know what cGMP is, most do not, it stands for cyclic guanosine monophosphate. This is naturally created by the tissue in the penis when there is sexual stimulation further allowing vascular muscle relaxation. When the levels of cGMP are good and consistent, the arteries have an opportunity to relax which allows a rigid erection to happen, unassisted.

Still, many want to know why if all three drugs have the same ingredients then why should they have to select one over another. On average, all three work in about 70% of men. The cost factor for the three puts them all in the same ballpark but Levitra is a bit cheaper. The side effects of all three are approximately the same. The length that they three last makes much more of a difference. Levitra lasts for about 5 hours, Viagra for about 4 hours, and Cialis for up to 36 hours.

Levitra does work the fastest with no regard to food consumption. Viagra has been branded and is trusted, with the highest sales, and Cialis lasts the longest, deemed the “weekender pill.” The rest is up to you to decide. Another great resource for deciding if Levitra or Viagra is right for you.
