Diabetes Drugs: GLP-1 Agonists

A curious fact that has been known almost since the discovery of insulin is that glucose taken by mouth stimulates insulin secretion to a greater degree than glucose that is injected straight into the bloodstream.

Diabetes Drugs: Alpha-Glucosidase Inhibitors

Alpha-glucosidase inhibitors, a class of drugs also known as “starch blockers,” function by slowing the absorption of certain carbohydrates in the gastrointestinal tract.
