    Phosphodiesterase-5 Inhibitors (PDE-5 Inhibitors) for Erection Problems and Benign Prostatic Hyperplasia



    How It Works

    During an erection, blood fills tissue in the penis, causing it to enlarge and become stiff. The PDE-5 inhibitors relax smooth muscle, allowing the penis to fill with blood.
