Glucagon-like peptide-1 (GLP-1) receptor agonists, also known as GLP-1 analogs, GLP-1DAs, or incretin mimetics, are a class of drugs used to treat type 2 diabetes and obesity.They work by mimicking the actions of the GLP-1 hormone, which is released by the gut after eating and prompts the body to produce more insulin to reduce blood sugar.
