Oral ED medication mechanism

Oral ED medications work by suppressing an enzyme in the body called PDE5. When PDE5 is suppressed, blood is able to flow more freely through the body—including to the (you guessed it) penis. More blood flow to the penis means harder, more satisfying erections once you’re sexually stimulated.
