Abstract:
This paper reviewed the efficacy and safety of vardenafil, a highly selective phosphodiesterase type 5 (PDE 5) inhibitor, in men with erectile dysfunction who were difficult to treat. Several large-scale studies indicated vardenafil was effective and safe in the treatment of these difficult-to-treat ED patients, including ED with depression or diabetes, ED after radical retropubic prostatectomy, ED caused by spinal cord injury, and sildenafil nonresponders. Vardenafil provides a rational treatment alternative.
