Why consumers overwhelmingly prefer Cialis
Since its 1998 introduction, Viagra (sildenafil) has become one of the world’s most recognizable brand names, up there with Coca-Cola and Rolls Royce. But in terms of user satisfaction, Viagra runs a distant second behind Cialis (tadalafil).
Remarkable Preference for Cialis
Men express remarkable preference for Cialis. I found 12 studies in which men tried both drugs and then reported which they chose to continue. The score was a shut-out: Cialis 12, Viagra 0. And the 8,300 participants favored Cialis by a wide margin, on average, three to one. In studies that also included the third major erection drug, Levitra (vardenafil), Cialis was substantially more popular than either competitor.
Women also prefer Cialis. In four studies, couples used Viagra then Cialis, or visa versa. Another shut-out. In all four trials, the women strongly preferred Cialis.
Why? Because Cialis has a longer duration of action. Viagra and Levitra last for around four hours, but Cialis lasts for 36. If a man takes Cialis on Friday evening, he has erection assistance through Sunday afternoon. Both men and women say they like the fact that Cialis allows them to take their eyes off the clock and make love whenever they wish. So Cialis has a clear advantage for dating couples or new lovers still in the hot-and-heavy period who value sexual spontaneity.
