Structurally vardenafil (Levitra) is similar to sildenafil, while tadalafil (Cialis) is very different. Vardenafil (Levitra) is almost 10 times more biochemically potent than sildenafil, therefore a lower dose is needed to facilitate the penile erection, potentially resulting in less side effects. Selectivity is the ability of the drug to attach to the specific enzyme PDE 5 found in penile tissues. Vardenafil (Levitra) is more selective than sildenafil and tadalafil (Cialis) to PDE5, which again means a lower dose is needed with potentially less side effects. Tadalafil is very specific for PDE5 and is also very specific for the enzyme PDE11. Unfortunately, we don’t know much about PDE11, which is found in the heart, in the pituitary gland in the brain and in the testicles.

In addition, N-desmethyl metabolite AUC and Cmax values significantly increased by 200% and 79%, respectively in subjects with severe renal impairment compared to subjects with normal renal function. The mean profiles of the change from baseline in standing systolic blood pressure in subjects treated with doxazosin in combination with 100 mg VIAGRA or matching placebo are shown in Figure 4.
