   Short Answer: Though a complicated chemical process, Levitra allows the muscles in the p***s to relax, which allows blood to flow in, creating a firm erection. Long Answer: Like Viagra and Cialis, Levitra is a phosphodiesterase-5 inhibitor (PDE-5). All of these drugs function in essentially the same way. In smooth muscle cells, cGMP (cyclic guanosine monophosphate) mediates smooth muscle relaxation. The more cGMP, the more the muscles can relax, the more blood can flow in, and the better the erection. PDE-5 breaks down cGMP, so PDE-5 inhibitors like Levitra keep this from happening, helping to maintain high levels of cGMP. Levitra's strong point is that it is very selective in attacking PDE-5 without affecting other isoenzymes. This allows a smaller dose of Levitra to have the same effect as a larger dose of Viagra (an average Levitra dose is 10mg while an average Viagra dose is 50mg), even though the two drugs essentially function the same way.
