Cialis is in a class of medications known as PDE-5 inhibitors, which are
used to treat cases of male impotence. Elli Lilly and Icos are currently
marketing Cialis in the U.S., UK, EU , and countries around the world.
Cialis acts in the same way as Viagra, by blocking an enzyme called
phosphodiesterase-5, or PDE-5. Cialis is more targeted than Viagra which
results in fewer sides effects and lower dosage. Cialis helps the smooth
muscles in the penis relax and widen, which allows for more blood to enter.
As a result, you gain erections faster and easier with Cialis.
