In response to the popularity of Viagra, many pharmaceutical manufacturing companies raced to develop their own ED medication, such as Cialis and Levitra. While these two latter medications have not yet reached the level of notoriety as Viagra, many industry experts predict that Cialis may eventually overtake the little blue pill as the most frequently used medication for erectile dysfunction. Although the mechanism of action in both drugs centers around PDE5 inhibition, Cialis uses Tadalafil instead of Sildenafil Citrate as the principal ingredient. The effect is largely the same, but there is one area of benefits where Cialis is far ahead.

The difference between Cialis and all of the other ED drugs has to do with the regularity of taking the drug. Both Levitra and Viagra are built on the idea that a pill should be taken slightly before sexual activity. While Cialis has a similar version, the main product is a lower dosage pill that is intended to be taken each and every day. In this manner, the amount of Tadalafil in the body is always at an effective level and there is no need to take a single dose immediately preceding sexual contact. This freedom is the closest that a man can get to having natural erectile functionality.

Entering the market in 2003, Cialis was the last of the three major ED drugs to make its debut. Since that time, it has been steadily gaining in market share due to the once daily strategy. The drug has also been approved as a way of treating arterial hypertension leading to more profits for the manufacturer. With more men caring about their level of sexual freedom when they choose the right ED medication, more are turning to Cialis rather than other drugs to aid them in overcoming the problematic sexual condition.
