The mean apparent level of distribution following oral administration is approximately 63 L, indicating that tadalafil is distributed into tissues.
Due to the longer half-life, treatment with nitrate medications must be deferred for at least 48 hours after ingestion of tadalafil, compared with a day for sildenafil and vardenafil . The vascular smooth muscle relaxation simultaneously vasodilates arterioles and trabecular smooth muscle sinusoids within erectile tissue to increase penile blood flow. Subsequently, compression of the subtunical venules resistant to the tunica albuginea occludes venous outflow. During the final phase of rigid erection, robust contraction of the ischiocavernous muscles constricts the bottom of the blood-filled corpora cavernosa, creating the penis to become even harder. Arterial inflow and venous outflow are temporarily occluded in this phase, and the intracavernous pressure can approach several hundred millimeters of mercury .
