The Ultimate Guide to Cialis and Tadalafil

Cialis® is the brand name for tadalafil, an FDA-approved medication for erectile dysfunction (ED), available in both as-needed and daily-use formulations. Approved in 2003 for as-needed use and in 2008 for daily use, Cialis works by relaxing blood vessels to enhance blood flow, helping men achieve and maintain erections when sexually aroused. The generic version of tadalafil provides the same benefits at a significantly lower cost.
