Liraglutide

Liraglutide

Overview

Liraglutide is a GLP-1 receptor agonist approved by the FDA for type 2 diabetes (Victoza) and obesity management (Saxenda). It was the first GLP-1 analog to demonstrate cardiovascular risk reduction in a large outcomes trial (LEADER trial), establishing the cardiovascular benefits of this peptide class. Liraglutide has one of the most extensive clinical evidence bases of any metabolic peptide with over a decade of post-market safety data and multiple completed Phase 3 trials across diabetes, obesity, and cardiovascular disease.

Mechanism of Action

Liraglutide shares the core GLP-1 receptor agonist mechanism — stimulating insulin secretion, suppressing glucagon, slowing gastric emptying, and reducing appetite through central hypothalamic pathways. Its 97% homology to native GLP-1 and albumin-binding fatty acid chain give it a half-life of approximately 13 hours, enabling once-daily dosing. Liraglutide also has direct effects on pancreatic beta-cell proliferation and survival, potentially preserving insulin secretory capacity over time. Its cardiovascular benefits in the LEADER trial — reducing major adverse cardiovascular events by 13% — appear mediated through direct GLP-1 receptor effects on cardiomyocytes, endothelial cells, and inflammatory pathways.

Dosage Information

1.2-1.8 mg daily (diabetes), up to 3.0 mg daily (obesity)

Frequency

Once daily

Administration

Subcutaneous injection

Notes

Titrated over 4-5 weeks. Requires medical supervision. Predecessor to semaglutide — semaglutide generally preferred for weight management due to once-weekly dosing and greater efficacy.
