The aim of the study is to investigate the effect of dapagliflozin or placebo on acetylcholine (Ach)- or nitroglycerin (GTN)-induced vasodilation of the forearm resistance vasculature, as determined by FBF measurement before and 10 minutes after 20 minutes of forearm ischemia.
The aim is to test the effect of dapagliflozin or placebo on ACh-induced vasodilatation of the forearm resistance vasculature as assessed by FBF measurement before and 10 min after a 20 min forearm ischemia as well as after a 14 day treatment period. The area under the dose-effect curve (AUC) of different ACh doses will be calculated and compared between treatment groups (dapagliflozin vs. placebo) and different time points (pre-ischemia vs. post-ischemia). FBF measurements will be made in response to increasing intra-arterial doses of ACh (25, 50, 100 nmol/min) to assess endothelial function or GTN (4, 8, 16 nmol/min) to test vascular smooth muscle vasodilator function.
