This medicine is a phosphodiesterase inhibitor which is used to treat erectile dysfunction (ED). After being sexual stimulated, Tadalafil tablets work by assisting the blood vessels in your penis to relax, which in turn allows blood to flow more easily into your penis. This process improves erectile function. Tadalafil (generic Cialis) will be able to assist you if you are suffering from erectile dysfunction. Cialis (tadalafil) relaxes muscles and increases blood flow to particular areas of the body.
