Sep 1, 2022 · Tirzepatide is the first dual GIP/GLP-1 receptor co-agonist approved for the treatment of type 2 diabetes in the USA, Europe, and the UAE. Tirzepatide is an acylated peptide engineered to activate the GIP and GLP-1 receptors, key mediators of insulin secretion that are also expressed in regions of the brain that regulate food intake. An agonist is a molecule that can bind and activate a receptor to induce a biological reaction. The activity mediated by agonists are opposed by antagonists, which inhibit the biological response induced by an agonist. The level of agonist required to induce a desired biological response is referred to as potency.
