What are Vardenafil Tablets

When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions. This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP). cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply the penis to dilate, while those removing blood from the penis contract. Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP.
