The medication Cenforce 150 is a member of the PDE 5 inhibitor pharmacological class. It includes sildenafil, which inhibits the PDE-5 enzyme's activity and permits healthy blood flow to the penis. Blood vessel dilatation and contraction are caused by cGMP. PDE 5 degrades cGMP and restricts blood flow. The sildenafil in Cenforce prevents PDE 5 from working and raises nitric oxide levels by preventing the breakdown of cGMP.
