Dulaglutide (Trulicity) vs Pramlintide (Symlin)
An educational, source-based comparison of Dulaglutide (Trulicity) and Pramlintide (Symlin) — 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.
Synthetic analog of the pancreatic hormone amylin. Slows gastric emptying, suppresses inappropriate postprandial glucagon, and increases satiety as adjunct to insulin.
- Type 1 diabetes (with insulin)
- Type 2 diabetes on insulin
- • FDA-approved.
- • Boxed warning: severe insulin-induced hypoglycemia.
