Vardenafil (Levitra) is an oral therapy for the treatment of erectile dysfunction. It is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). The tissue concentration of cGMP is regulated by both the rates of synthesis and degradation via phosphodiesterases (PDEs).
Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles.
The most abundant PDE in the human corpus cavernosum is the cGMPspecific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP.
The cGMP in turn triggers smooth muscle relaxation, allowing increased blood flow into the penis, resulting in erection.
During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells in the corpus cavernosum. Nitric oxide activates the enzyme guanylate cyclase resulting in increased synthesis of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum.
Cialis, Levitra, and Viagra are all in a class of drugs called PDE-5 inhibitors. Relaxed muscles allow blood to flow freely so that when you’re aroused, you can get an erection. It also helps you maintain the erection long enough to have sex. These drugs work by blocking an enzyme called phosphodiesterase type 5. They also boost a chemical in your body called nitric oxide. This action encourages the muscles in your penis to relax.
Levitra and Viagra stay in your bloodstream for about four to six hours. Cialis remains in your bloodstream for 17 to 18 hours or longer. The length of time a drug stays in your system may be important if you’re taking other medications.

Vardenafil has been licensed to treat erectile dysfunction. Erectile dysfunction (ED), also known as impotence, can be a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Essentially, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse.
