About this study

Glucagon-like peptide-1(GLP-1) is secreted during a meal and increases glucose induced insulin secretion. The enzyme dipeptidyl peptidase 4(DPP-4) cleaves intact GLP-1 within minutes and DPP-4 inhibitors are therefore used for treatment of diabetic hyperglycemia. A few animal studies have implicated the enzyme neutral endopeptidase 24.11 (24.11) in the degradation of GLP-1 but if this is the case in humans is unknown. We therefore administered a NEP inhibitor, 194mg sacubitril, a DPP-4 inhibitor (sitagliptin 100mg the night before and 100mg 2 hours before), both, or place, to nine healthy men during a standardized meal and measured plasma concentrations of GLP-1
