Summary
Recent studies in both animals and humans has demonstrated that the hormone GLP-1 (glucagon like peptide 1) reduces intestinal production of lipoprotein particles. The investigators therefore hypothesise that the drug sitagliptin which prevents the breakdown of GLP-1 will reduce intestinal lipoprotein production in humans. The investigators are unable to speculate whether sitagliptin will affect hepatic lipoprotein production because of lack of of data from animal studies or in vitro data. Sitagliptin is already an approved treatment for type 2 diabetes.
