Metabolic peptides are at the forefront of modern research into weight management, insulin sensitivity, and energy metabolism. Liraglutide is being studied for its potential role in metabolic regulation and related pathways.
A GLP-1 receptor agonist approved for type 2 diabetes and obesity. Reduces appetite, slows gastric emptying, and has demonstrated cardiovascular protective effects in trials.
Also Known As
Victoza, Saxenda
What is Liraglutide?
Liraglutide is classified under the Metabolic category of peptides. A GLP-1 receptor agonist approved for type 2 diabetes and obesity. Reduces appetite, slows gastric emptying, and has demonstrated cardiovascular protective effects in trials.
Mechanism of Action: A GLP-1 receptor agonist with 97% homology to native GLP-1, featuring an acyl side chain that promotes albumin binding and self-association, extending its half-life to approximately 13 hours. Stimulates glucose-dependent insulin secretion, suppresses glucagon, delays gastric emptying, and promotes satiety.
Metabolic Research & Applications
Primary Research Areas: Type 2 diabetes, obesity, cardiovascular risk reduction, NASH.
Key Research Findings: FDA-approved for diabetes (Victoza) and obesity (Saxenda). The LEADER trial showed cardiovascular benefits with reduced MACE. SCALE trials demonstrated significant weight loss in obese patients. One of the earliest long-acting GLP-1 RAs.
Safety Profile & Considerations
Well-characterized safety profile from extensive clinical use. Common GI side effects (nausea, vomiting). Rare risks include pancreatitis and thyroid C-cell concerns. Contraindicated in MTC/MEN 2.
