Liraglutide

A once-daily GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and, at a higher dose, for chronic weight management (Saxenda). It was the first GLP-1 agonist to secure a dedicated obesity indication.

Overview

Liraglutide — a glp-1 receptor agonist — sits in the "Approved medicine" tier of this catalog. This compound exists as an approved medicine in at least one major jurisdiction. Approval applies to specific, labeled indications and to the regulated product — not to compounded or research-grade copies.

A once-daily GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and, at a higher dose, for chronic weight management (Saxenda). It was the first GLP-1 agonist to secure a dedicated obesity indication.

Mechanism of Action

Liraglutide is a GLP-1 analog with a C16 palmitoyl side chain that enables albumin binding and extends its half-life to roughly 13 hours, permitting daily subcutaneous dosing. Its pharmacology follows the class: glucose-dependent insulin secretion, glucagon modulation, slowed gastric emptying, and appetite reduction.

Research and Evidence

The SCALE obesity trial (n=3,731) reported about 8% mean weight loss over 56 weeks with 3.0 mg daily versus 2.6% with placebo, and the LEADER cardiovascular outcomes trial in type 2 diabetes showed a reduction in major cardiovascular events.

Evidence in context: the GLP-1 and Incretin Therapies class page collects the shared evidence themes and study-reading guidance for this category.

Safety and Side Effects

Nausea and vomiting are the most common effects; labeled warnings include gallbladder disease, pancreatitis, and the class medullary thyroid carcinoma/MEN2 contraindication.

Educational notice: this entry describes published research and, where they exist, regulator labels. It is not medical advice and not a recommendation for use. Research-grade compounds have no verified human-safety data.

Frequently Asked Questions

What is the evidence tier of Liraglutide?

Liraglutide is graded "Approved medicine" on this site. This compound exists as an approved medicine in at least one major jurisdiction. Approval applies to specific, labeled indications and to the regulated product — not to compounded or research-grade copies.

Is Liraglutide an approved medicine?

Liraglutide exists as an approved medicine in at least one major jurisdiction — but approval covers the regulated product and its labeled indications only. Compounded or research-grade versions of the same molecule are not the approved product.

Where can I read the primary studies for Liraglutide?
