Clinical Application of Glucagon-Like Peptide-1 Receptor Agonists / 임상당뇨병

ABSTRACT

Glucagon-like peptide 1 (GLP-1) is an incretin hormone that is released from enteroendocrine L-cells upon nutrient absorption; it stimulates glucose-dependent insulin secretion from pancreatic betacells. GLP-1 has pleiotropic effects including deceleration of gastric emptying, decreased appetite, and increased satiety. Treatment with GLP-1 receptor agonists (GLP-1RAs) improves glycemic control in patients with type 2 diabetes without increasing the risk of hypoglycemia or weight gain. Current GLP-1RAs can be classified by their structure (exendin-4-based or human GLP-1-based), duration of action, and molecular size. Different GLP-1RAs exhibit different pharmacokinetics and pharmacodynamics. Herein we review the characteristics of available GLP-1RAs and discuss current issues such as insulin combination therapy and anti-obesity effects.
