Sildenafil’s mechanism of action 

The active ingredient sildenafil is an oral therapy for erectile dysfunction. In a natural setting, i.e. with sexual stimulation, it restores impaired erectile function by increasing blood flow to the penis.

The physiological mechanism responsible for penile erection involves the release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. Nitric oxide then activates the enzyme guanylate cyclase, leading to increased levels of cyclic guanosine monophosphate (cGMP), which induces smooth muscle relaxation in the corpus cavernosum and allows blood inflow.

Sildenafil is a potent and selective inhibitor of cGMP-specific phosphodiesterase type 5 (PDE5) in the corpus cavernosum, where PDE5 is responsible for cGMP degradation. Sildenafil has a peripheral effect on erection.
