Dulaglutide (Trulicity) vs Liraglutide
An educational, source-based comparison of Dulaglutide (Trulicity) and Liraglutide — how each peptide works, what it's researched for, and what to know before going deeper.
Once-weekly GLP-1 agonist with cardiovascular benefit.
GLP-1 analog fused to a modified human IgG4 Fc fragment, giving a half-life that supports weekly dosing. Improves glycemia and reduces MACE in T2D.
- Type 2 diabetes
- Cardiovascular risk reduction in T2D
- • FDA-approved.
- • Boxed warning: thyroid C-cell tumors in rodents.
A daily GLP-1 receptor agonist with a fatty-acid side chain that enables albumin binding and ~13-hour half-life. Mechanism mirrors semaglutide at shorter duration: enhanced glucose-dependent insulin release, slowed gastric emptying, and central appetite suppression.
- Type 2 diabetes (Victoza)
- Chronic weight management (Saxenda)
- Cardiovascular risk reduction in T2D
- • FDA-approved; requires prescription and physician oversight.
- • GI side effects, pancreatitis risk, gallbladder events.
