Postprandial blood glucose modulation

"Postprandial blood glucose modulation" refers to the regulation of blood glucose concentrations following a meal. After eating, blood glucose rises due to carbohydrate absorption, which is then tightly modulated through the interplay of insulin (from pancreatic beta-cells), inhibition of glucagon (from alpha-cells), action of incretin hormones (e.g., GLP-1), changes in hepatic glucose uptake, muscle glucose disposal, and slower gastric emptying[1][2][3][5][6]. This finely tuned process prevents excessive hyperglycemia and subsequent hypoglycemia, and is disrupted in conditions such as diabetes mellitus. Key caveat: "Postprandial blood glucose modulation" is not a molecule, receptor, or classic molecular drug target but a complex, multifactorial physiological process involving numerous druggable targets (e.g., insulin receptor, GLP-1 receptor, SGLT2) and pathways[1][2][3][5]. Any drug intervention targets one or more components within this network.

Mechanisms vary by drug due to the process involving multiple pathways: Stimulate insulin secretion (e.g., sulfonylureas). Mimic incretin hormones to enhance insulin and suppress glucagon after meals (e.g., GLP-1 receptor agonists, DPP-4 inhibitors). Delay carbohydrate absorption from the gut (e.g., alpha-glucosidase inhibitors). Inhibit renal glucose reabsorption (e.g., SGLT2 inhibitors). Provide exogenous insulin to counter postprandial rises.
