About
About Liraglutide
Liraglutide is a once-daily GLP-1 receptor agonist marketed as Victoza for type 2 diabetes and Saxenda for chronic weight management. It was one of the first GLP-1 agents to demonstrate meaningful weight loss in clinical trials, producing 5–8% body weight reduction on average. Though largely superseded by weekly agents, it remains a clinically validated option. Compounded liraglutide is available through select pharmacies.
Science
Mechanism of Action
Mimics endogenous GLP-1 by binding to GLP-1 receptors in the pancreas, hypothalamus, and gut, increasing insulin secretion, slowing gastric emptying, and reducing appetite. Its 13-hour half-life requires daily dosing.
Dosing
Typical Protocol
0.6 mg subcutaneous once daily for 1 week, titrating weekly to a maximum of 3.0 mg/day.
