Vardenafil, which the world also known by the brand name called Levitra, is a prescription medicine that helps to treats male erectile dysfunction. Erectile dysfunction is whilst a man is not able to get or preserve an erection. It normally takes place due to the fact that the arteries that bring the blood to the penis are too narrow. Vardenafil help to increase blood glide or flow to the penis. Its work is much like that of sildenafil, or Viagra, however Viagra lasts between 2 and 4 hours, while Levitra lasts 4 hours. In the course of a penile erection, the penis is filled with blood. The blood vessels that supply the penis with blood increase, or dilate, and the vessels that take blood away from the penis contract. The two large chambers in the penis, called the Corpus Cavernosa, fill with blood. As the blood accumulates in the penis, an erection is the end result.
