Levitra is characterized as a phosphodiesterase type 5 inhibitor. Drugs classified in this manner are medication that is used to slow lower or avoid the phosphodiesterase type 5 from breaking down the blood vessels located within the corpus cavernosum within the penis, particularly along the smooth muscle cells therein. Sexual stimulation for the most part, happens when nitric oxide (or NO for short) is released to the corpus cavernosum's vasculature. Nitric oxide are accountable for the activation of an enzyme known as guanylate cyclase, which in turn also causes cyclic guanosine monophosphate. The smooth muscle cells discovered in the blood vessels of the corpus cavernosum, when the required levels of cyclic guanosine monophosphate is reached, is then relaxed, allowing more blood circulation in the region. Blood flow can then easily increase in the penis, which then allows erection to take place.

Most PDE5 inhibitors however, are still regarded as useless without the correct sexual stimulation to consider location. PDE5 inhibitors are only useful because they help to inhibit the GMPs' degredation during the erection procedure. Since GMP is only present when sexual intercourse is getting stimulated, arousal is needed for drugs like these to work.
