Cialis for erectile dysfunction

Cialis is the latest drug approved by the FDA for impotence treatment. Prior to approving Cialis in December 2003, the FDA had approved Viagra in March 1998 and Levitra in August 2003. All the 3 medications viz. Viagra, Levitra and order cialis belong to the same class of medicines called PDE5 inhibitors and therefore their mechanism of action is the same. However, having enjoyed complete monopoly for 5-years, Viagra became a household name as well as the most popular impotence treatment drug.

Levitra, a slightly improved version of Viagra in terms of time taken to become effective and the duration it remains effective, failed to break the monopoly of Viagra in the oral impotence pills market. cheap cialis, on the other hand, captured the attention just when it was launched. In fact, Cialis is giving both Viagra and Levitra a run for their money as it has become one of the most prescribed impotence treatment drugs mainly because of its fast acting and longer-lasting properties.
