Liraglutide

Liraglutide is a long-acting glucagon-like peptide-1 receptor agonist used to improve blood-glucose control in type 2 diabetes and support chronic weight management.

GLP-1 receptor: A cell-surface receptor activated by glucagon-like peptide-1 and related medicines to regulate glucose and appetite. Liraglutide activates this receptor to produce its metabolic effects.
Type 2 diabetes: A chronic metabolic disease in which insulin resistance and impaired insulin secretion cause elevated blood glucose. Liraglutide improves glycemic control in adults with this disease.
Semaglutide: A long-acting GLP-1 receptor agonist used for type 2 diabetes and chronic weight management. It targets the same receptor but generally requires less frequent dosing than liraglutide.
LEADER trial: A randomized trial testing liraglutide's cardiovascular effects in people with type 2 diabetes at high cardiovascular risk. It found fewer major cardiovascular events with liraglutide than with placebo.
Glucagon-like peptide-1: An intestinal and neural hormone that helps regulate blood glucose, appetite, and digestion. Liraglutide imitates this hormone but persists much longer in circulation.
Obesity: A chronic disease involving excess body fat that can impair health. Liraglutide is prescribed at a higher dose for chronic weight management in eligible patients.
Dulaglutide: A long-acting GLP-1 receptor agonist used to treat type 2 diabetes. Its once-weekly injection schedule contrasts with liraglutide's daily administration.
SCALE Obesity and Prediabetes trial: A clinical trial evaluating liraglutide 3.0 mg for weight management in adults with obesity or overweight and related conditions. It tested the higher dose used for chronic weight management.
Insulin secretion: The release of insulin from pancreatic beta cells into the bloodstream. Liraglutide increases glucose-dependent insulin release through GLP-1 receptors.
Victoza: A brand-name liraglutide injection approved for type 2 diabetes treatment. This formulation delivers liraglutide at doses used primarily for diabetes.
