Cialis was developed in 2003 as follow-up to Viagra and Levitra. Together with the other two ED pills, it enters into the class of phosphodiesterase type 5 inhibitors (PDE5), or cyclic guanosine monophosphate-specific phosphodiesterase type 5 (cGMP PDE5) inhibitors, to be more precise.In the first of these studies, 348 patients with ED were randomized to placebo or Cialis 20 mg. Patients were encouraged to make 4 total attempts at intercourse; 2 attempts were to occur at 24 hours after dosing and 2 completely separate attempts were to occur at 36 hours after dosing. The results demonstrated a difference between the placebo group and the Cialis group at each of the pre-specified timepoints. At the 24-hour timepoint, (more specifically, 22 to 26 hours), 53/144 (37%) patients reported at least 1 successful intercourse in the placebo group versus 84/138 (61%) in the Cialis 20-mg group. At the 36-hour timepoint (more specifically, 33 to 39 hours), 49/133 (37%) of patients reported at least 1 successful intercourse in the placebo group versus 88/137 (64%) in the Cialis 20-mg group.
