Liraglutide
GLP-1 agonist
An earlier daily-injection GLP-1 agonist—still used for diabetes and weight loss.
Liraglutide was the first GLP-1 drug widely used for obesity (Saxenda). It works similarly to semaglutide but requires daily dosing and tends to produce somewhat less weight loss. Well-studied safety profile over many pa…
Semaglutide
GLP-1 agonist
A GLP-1 receptor agonist peptide drug approved for type 2 diabetes and chronic weight management.
Semaglutide mimics glucagon-like peptide-1, slowing gastric emptying and increasing satiety. Weekly injection versions (Ozempic, Wegovy) produce significant weight loss in trials. It is a prescription drug—not a supple…
