Brief Summary
Given the protective effect of nitric oxide (NO) on the endothelium and the results obtained so far in short-term, continuous treatment with phosphodiesterase-5 (PDE5) inhibitors on parameters of endothelial function, we hypothesise that chronic treatment with vardenafil can prevent or delay the deterioration of systemic endothelial function in patients with type 2 diabetes mellitus. The favourable effect of PDE5 inhibitors on sexual function in these patients has been convincingly demonstrated in the past. Here we hypothesise that vardenafil treatment can have beneficial effects on the vascular physiology in other body districts, possibly preventing the development of microangiopathy and atherosclerotic cardiovascular disease in these patients. The main goal of this study is therefore to monitor the endothelial dysfunction during continuous treatment with vardenafil for 6 months; object of the study will be endothelin 1 and other known parameters of endothelial damage in newly diagnosed patients with type 2 diabetes mellitus.

Vardenafil
EXPERIMENTALThe study protocol consists of a Screening/Enrolment Phase lasting up to 4 weeks, a Treatment Phase of 24 weeks, and Follow-up/Observation Treatment-free Phase of 24 weeks after the Treatment Phase. During treatment phase, patients enrolled in the Study Group were treated with vardenafil 10 mg twice/daily.
Control
PLACEBO COMPARATORThe study protocol consists of a Screening/Enrolment Phase lasting up to 4 weeks, a Treatment Phase of 24 weeks, and Follow-up/Observation Treatment-free Phase of 24 weeks after the Treatment Phase. During treatment phase, patients enrolled in the Control Group were treated with tablets twice/daily identical to the Study Group, but containing placebo.
