These drugs impede the functioning of PDE5, an enzyme within the blood vessel walls that helps control blood flow.
Following arousal, the body releases enzymes that cause blood vessels in the smooth muscles to relax, allowing for more blood flow. PDE5 inhibitors block the degradation of these enzymes, increasing blood flow and resulting in an erection.
It is important to note that a person needs to be aroused for a PDE5 inhibitor to help with ED.
