5. Study Description
Brief Summary
This is a double-blind, placebo-controlled, cross-over trial using a single dose of 100 mg sildenafil or placebo in 40 subjects with T2DM without known cardiovascular disease. Effects on haemodynamic parameters, flow mediated dilatation (FMD) in brachial artery, cardiovascular autonomic function tests, and spontaneous baroreflex sensitivity (BRS) were investigated.
