A GLP-1 receptor agonist refers to a category of compounds that bind to and activate the receptor for glucagon-like peptide-1, a naturally occurring hormone involved in metabolic and digestive signalling. Many compounds in this class are peptide-based molecules designed to mimic the action of the natural hormone.
These compounds are the subject of substantial scientific and clinical research. As peptide-based agents, they are typically administered by injection because oral delivery is limited by digestion in the gastrointestinal tract.
In Australia, medicines in this class are prescription-only and regulated by the Therapeutic Goods Administration. This entry describes the class as a pharmacological category rather than endorsing any specific product or use.
