Overview

Guide On the Male Enhancement Supplement for Improving Sex Drive and Increasing Libido. 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. Vardenafil belongs to a category of medication referred to as phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries. By relaxing the arteries, vardenafil help to increase the blood flow when a man is sexually aroused. The active ingredient works at the chain of reactions in the penis at some point of arousal. Whilst a male is sexually aroused, nitric oxide is released into his penis, and this triggers a sequence of reactions. This make an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP). cGMP regulates the contraction and dilation, or enlargement, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply the penis to dilate, at the same time as the ones disposing blood from the penis contract. Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP. Whilst cGMP is destroyed, the blood vessels go back to their normal size, successfully ending the erection. Vardenafil help to stops PDE5 from destroying cGMP. On this note, it permits cGMP to work for a longer period of time. On the other note, it helps to prolong an erection.
