Men with erectile dysfunction (ED) can be treated with the drug Tazzle. The active component, tadalafil, which is also present in Cialis, helps increase blood flow to the penis, resulting in a powerful and long-lasting erection. Tadalafil, a PDE5 inhibitor found in Tazzle, relaxes blood vessels and boosts blood flow to the penis, assisting in the initiation and maintenance of an erection.
