How Liraglutide works

Liraglutide activates the GLP-1 receptor to reduce appetite, slow gastric emptying, and improve insulin secretion. It shares the same mechanism as semaglutide but has a shorter half-life requiring daily dosing.

Reported benefits

Based on published clinical trials, Liraglutide has been associated with the following benefits:

FDA-approved for weight management
Well-studied safety profile
Available in daily injection pen format

Supporting research

A Randomized, Controlled Trial of 3.0 mg of Liraglutide in Weight Management (SCALE)

New England Journal of Medicine, 2015 · PMID: 26132939

8% mean body weight loss over 56 weeks vs 2.6% placebo.

Important context

Benefits reported in clinical trials represent average outcomes across study populations. Individual results vary based on genetics, dosage, duration, and lifestyle factors.
