How Tadalafil works

In order for the penis to erect, there is the production of nitric oxide from the corpus cavernosum when one is stimulated sexually. The nitric oxide released then activates guanylate cyclase leading to higher levels of cyclic guanosine monophosphate, which leads to smooth relaxation of muscles in the corpus cavernosum, leading to easy flow of blood. Tadalafil boosts the influence of nitric oxide by hindering PDE5, leading to high levels of cGMP that leads to better erection, although sexual stimulation is needed.

Tadalafil also inhibits PDE5 in the tissues of the lungs and the esophagus smooth muscle. Inhibition of PDE5 that occurs in the lung tissues makes the pulmonary vascular smooth muscle to relax. This also leads to pulmonary vasodilation, making the drug effective in treatment of pulmonary hypertension.
