Two of these trials were conducted in special erectile dysfunction populations; one in men with diabetes mellitus, another in men who developed erectile dysfunction after prostate surgery. The doses of vardenafil in the four studies were 5 mg, 10 mg, and 20 mg. cialis american online pharmacy buy cialis online
