Pharmacodynamics and pharmacokinetics

The main active ingredient of Cialis tablets tadalafil improves the erectile function of the penis, increasing blood flow to the corpus cavernosum. This is due to the suppression of the enzyme phosphodiesterase 5, which in turn leads to the accumulation of nitric oxide in the corpus cavernosum. Nitric oxide stimulates the accumulation of cyclic guanine triphosphate ( cGMP ), which reduces the tone of the walls of the vascular bed, expands their lumen, and also expands arterial vessels, helping to increase blood flow to the cavernous bodies of the penis with an improvement in erection.

After taking the Cialis tablet inside, the active ingredient tadalafil is quickly and almost completely absorbed into the blood from the lumen of the small intestine. It reaches its maximum concentration in the blood after 2 hours. Tadalafil is evenly distributed in tissues, enters the cavernous bodies, where it has a therapeutic effect. It is metabolized in the liver with the formation of inactive decay products, which are excreted from the body mainly in the feces and to a lesser extent in the urine. The therapeutic effect after taking the Cialis tablet develops within 15-20 minutes and can persist for a period of up to 36 hours.
