Although Cialis and Viagra belong to the same medical group, many men prefer Cialis to Viagra. Different clinical studies in 2003, 2005 and 2006 proved this. Approximately 70 % of patients first use Viagra and than switch to Cialis. As you can see Viagra is a popular drug for most of “newcomers”. Still popularity alone must not be a determining factor.

Numbers, numbers, numbers
Many researches have been held to determine what PDE5 inhibitors are preferred by men. Of course, it is not easy to compare the effect of such E.D. drugs as Viagra and Cialis based on different studies because researches have used various criteria and selected particular groups of patients. Still numbers can speak for popularity of this or other medication.
A research made by Stroberg P. in 2003 showed that 9 out of 10 patients who started with Viagra then replaced it with Cialis. Two years later Eardly I. carried out another experiment. It turned out that 71 % of men preferred Cialis to Viagra. Lee examined what PDE5 inhibitors were preferred by sexual partners in 2006. About 2600 men with erectile dysfunction participated in this study. The results were much alike with the previous researches: 71 % of patients started with Viagra and then switched to Cialis, and 29 % of patients switched from Cialis to Viagra.
Reasons to Choose
No matter what PDE5 inhibitor was chosen by patients with E.D., the main reasons for preferring one medication to another were similar.
Men who chose Cialis enjoyed the duration of this drug action (about 45 % of patients). Other reasons for choosing Cialis included improved erections (34-37 %), easiness to use (7 %) and the best tolerance (8-9 %).
Men who chose Viagra enjoyed it because this drug gave them better erections (64 % of cases). Other reasons for choosing Viagra included better tolerance (16-17 %), duration (6 %), easiness to use (2-6 %), drug affordance (2-4 %). Some patients (2 %) enjoyed Viagra because it was released earlier than Cialis.
Your Choice
Viagra hit the market in 1998. Six years later its sales amounted to just $ 1.4 billion. Sales of pain and epilepsy were far more! However drugmakers weren’t stopped by this fact and got onto the market with Levitra and then Cialis.
It’s difficult to tell what PDE-5 inhibitor is better. It’s up to your own preferences. Both drugs (Viagra and Cialis) are approved by FDA and highly effective. So find the best alternative for yourself and prove you are a lion in bed!
