Abstract

Incretins such as glucagon-like peptide-1 (GLP-1) are gut-derived hormones that stimulate insulin secretion and suppress glucagon secretion, thus playing a key role in glucose homeostasis. While incretin mimetics and enhancers are approved for treatment of outpatients with diabetes, evidence is only starting to accumulate regarding the therapeutic potential of incretins in hospitalized patients. Small exploratory studies suggest that GLP-1 safely reduces hyperglycemia without causing hypoglycemia, a key advantage over insulin if efficacy is established in larger studies. Potential limitations include the need for a continuous infusion for delivery, attenuation but not normalization of glucose levels, increased deceleration of gastric emptying and nausea. The exact mechanism of action, dosing, adverse effects, patient subgroups that would be most suitable and safety of combination treatment with insulin remain to be studied. While promising, additional research is required studying effects on hard clinical endpoints.
