Mechanism and action
Cialis Professional: Tadalafil inhibits PDE5 in penile tissue and other vascular smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate, relaxing smooth muscle and increasing blood inflow. Caverject: Alprostadil binds prostaglandin E receptors on smooth muscle of the corpus cavernosum, triggering cAMP-mediated relaxation of cavernosal smooth muscle independent of the nitric oxide pathway used by PDE5 inhibitors.
