Cenforce 100 mg belongs to a class of drugs known as PDE 5 inhibitors. It contains Sildenafil that blocks the action of the PDE 5 enzyme and allows the blood flow properly to the penis.

cGMP is responsible for the contraction and dilation of blood vessels. PDE 5 breaks down cGMP and obstructs the flow of blood. Sildenafil present in Cenforce 100 blocks the action of PDE 5 and increases the levels of nitric oxide by inhibiting the breakdown of cGMP. Once cGMP is produced properly, blood flows easily to the penis. As more and more blood flows to the penis, a pressure is created. This results in an erection.
