Dulaglutide vs Exenatide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Dulaglutide
Dulaglutide (Trulicity) is a once-weekly GLP-1 receptor agonist for type 2 diabetes. Its larger molecular size from fusion with an Fc fragment extends half-life and may reduce some GI side effects.
Full details →Exenatide
Exenatide was the first GLP-1 receptor agonist approved in the US, derived from a compound found in Gila monster saliva. Available as Byetta (twice daily) and Bydureon (once weekly extended-release).
Full details →Side-by-Side Comparison
| Aspect | Dulaglutide | Exenatide |
|---|---|---|
| Mechanism | GLP-1 analog fused to a modified human IgG4 Fc fragment, providing extended duration of action. Activates GLP-1 receptors for glucose-dependent insulin secretion and appetite suppression. | Synthetic version of exendin-4, which activates GLP-1 receptors to enhance glucose-dependent insulin secretion, suppress glucagon, slow gastric emptying, and promote satiety. |
| Typical Dosage | Start at 0.75mg once weekly, may increase to 1.5mg, 3mg, or maximum 4.5mg weekly based on glycemic response. | Byetta: 5mcg twice daily for 1 month, then 10mcg twice daily. Bydureon: 2mg subcutaneously once weekly. |
| Administration | Subcutaneous injection once weekly, any time of day, with or without food. Comes in pre-filled single-dose pens. | Byetta: Inject within 60 minutes before morning and evening meals. Bydureon: Any time of day, with or without meals. Do not mix with insulin in same syringe. |
| Side Effects | Nausea, diarrhea, vomiting, abdominal pain, decreased appetite. Generally well-tolerated with gradual dose titration. | Nausea (especially initially), vomiting, diarrhea, dizziness, headache, and injection site reactions (particularly with Bydureon). |
