Brief summary
In the current study we wish to investigate the effects on glucagon-like peptide-1 (GLP-1) of a neprilysin inhibitor
Detailed description
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
Interventions
Single dose administration of Entrestro 194 mg sacubitril / 206 mg valstartan
2 x 100mg sitagliptin as single dose.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| C-peptide | 3 hours after treatment ( during the subsequent standardized meal) | changes in C-peptide using immunological methods |
| Glucagon | 3 hours after treatment ( during the subsequent standardized meal) | Changes in Plasma glucagon concentrations using different analytical methodologies |
Other
| Measure | Time frame | Description |
|---|---|---|
| Blood glucose | 3 hours after treatment and during the subsequent standardized meal | changes in blood glucose using immunological methods |
