ABSTRACT
<p><b>OBJECTIVE</b>To observe the efficacy and safety of vardenafil in the treatment of erectile dysfunction (ED) in aged men with diabetes mellitus (DM).</p><p><b>METHODS</b>One hundred outpatients with diagnosed ED (40 diabetic and 60 non-diabetic) received vardenafil at the initial dose of 20 mg and sustained dose of 10 mg once a week for 8 weeks, and their erectile functions were evaluated by IIEF and EQS.</p><p><b>RESULTS</b>The scores on IIEF and EQS in the diabetic ED group were 18.9 +/- 0.2 and 25.1 +/- 1.4 after the vardenafil treatment, significantly higher than 8.1 +/- 0.5 and 9.1 +/- 1.3 before the treatment (P < 0.01), and the non-diabetic group scored 21.1 +/- 0.2 and 34.2 +/- 1.2 on IIEF and EQS after the treatment, as compared with the statistically lower scores of 10.1 +/- 0.3 and 10.1 +/- 1.7 before it (P < 0.01). The total rate of effectiveness was 65% in the diabetic and 73.30% in the non-diabetic group, with statistical differences (P < 0. 05).</p><p><b>CONCLUSION</b>Vardenafil can significantly improve erectile function and is well tolerated in the aged males with diabetic ED.</p>
