PDE5 inhibitors directly affect the penis, causing the blood vessels to loosen up as a result. Erection is made possible by better blood flow in the area.

The erection process is really complicated. The nervous system around the penile area is stimulated during sexual activity. Nitric oxide is a kind of molecule that is released as a result of this process (NO). Nitric oxide in undetermined quantities enhances the exposure of cyclic GMP, a different chemical. This chemical increases the blood flow in the penile area by 40 times and aids in relaxing the blood vessels muscle.

PDE5 inhibitors help to degrade cyclic GMP molecules and reverse the erection process. They have cyclic GMP-like structures that prevent Phosphodiesterase 5 inhibitors from causing this breakdown. Nitric oxide is enhanced by this mechanism, supporting blood flow in the penis area.
