Cialis working

Cialis tadalafil works by blocking the PDE5 inhibitors. When Cialis blocks the PDE5 inhibitors, other chemicals responsible for erection continue to maintain their levels in the penis. This action allows the muscles of the penis to expand and as a result the blood flows and stays in the penis for a longer time and allows man to achieve as well as maintain an erection.
