Understanding Erectile Dysfunction Medications: Can Cialis Help with Longevity? Cialis, a medication prescribed to treat erectile dysfunction (ED), has been on the market since 2003.
Its active ingredient, tadalafil, improves blood flow to the penis by inhibiting the phosphodiesterase type 5 enzyme and allowing cyclic guanosine monophosphate to accumulate. What is Cialis and How Does it Work?
Tadalafil works by blocking the PDE5 enzyme, which breaks down cGMP. This leads to increased blood flow and improved erectile function.
