Clinical Pharmacology

Cialis is a treatment for male erectile dysfunction or impotence, as well as pulmonary arterial hypertension or PAH. Generally, the physiological procedure of the erection of the penis involves the secretion of nitric oxide or NO in the corpus cavernosum. After this, the guanylate cyclase enzyme is activated, which improves cyclic guanosine monophosphate (cGMP) levels. Higher cGMP levels result in an enhanced inflow of blood and successful erection of the penis. Cialis is a unique and robust inhibitor under cGMP specific phosphodiesterase type 5 (PDE5), which means that it facilitates the degradation of cGMP in the corpus cavernosum. When Cialis is inside the patient’s body, regular sexual stimulation results in improved amounts of cGMP in the corpus cavernosum and leads to greater erections. But, when sexual stimulation and NO/cGMP system activation is absent, Cialis cannot cause a successful erection.
