As our understanding of the incretin hormone system has increased, a number of drugs targeting this system have been developed. The realisation of this potential has developed rapidly, and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are now a standard feature in management guidelines for type 2 diabetes. This article reviews the operation of the incretin system and the mechanism by which GLP-1 RAs act to provide benefit in type 2 diabetes. The availability and indications for use of the GLP-1 RAs, and their clinical benefits and disadvantages, are summarised. The position of GLP-1 RAs in the management of type 2 diabetes is discussed pragmatically, with reference to various key guidelines.
