Liraglutide (NN2211) is a long-acting glucagon-like peptide-1 receptor agonist, binding to the same receptors as does the endogenous metabolic hormone GLP-1 that stimulates insulin secretion. Marketed under the brand name Victoza, it is an injectable drug developed by Novo Nordisk for the treatment of type 2 diabetes. In 2015, Novo Nordisk began marketing it in the U.S. under the brand name Saxenda as a treatment for obesity in adults with at least one weight-related comorbid condition.
