Dulaglutide
Dulaglutide consists of two modified GLP-1(7-37) sequences covalently linked to a human IgG4-Fc. The Fc fusion increases molecular weight substantially (~60 kDa), reduces renal filtration and extends the half-life to several days. GLP-1 receptor activation glucose-dependently stimulates insulin secretion, inhibits glucagon, delays gastric emptying and modulates central satiety signalling.
Exenatide
Exenatide is a 39-amino-acid peptide with about 53% sequence homology to human GLP-1. A glycine substitution at position 2 prevents dipeptidyl-peptidase-IV cleavage and extends the half-life from native GLP-1 (minutes) to about 2.4 hours. GLP-1 receptor activation glucose-dependently stimulates insulin secretion, inhibits glucagon and delays gastric emptying.

Frequently asked questions
- What is the difference between Dulaglutide and Exenatide?
- Dulaglutide is classified as "Метаболизм", while Exenatide is classified as "Метаболизм". Dulaglutide: GLP-1 receptor agonist designed as a fusion protein of two modified GLP-1(7-37) sequences covalently linked to a human IgG4-Fc fragment. FDA-approved 2014 (Trulicity) for type 2 diabetes; EMA approval 2014. Exenatide: Synthetic version of exendin-4, originally isolated from the saliva of the Gila monster (Heloderma suspectum). First GLP-1 receptor agonist, FDA-approved 2005 as Byetta. Weekly depot form Bydureon approved 2012. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Dulaglutide or Exenatide?
- The highest available evidence level is "РКИ на людях" for Dulaglutide and "РКИ на людях" for Exenatide. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Dulaglutide and Exenatide in Germany and the United States?
- Германия: Dulaglutide — Рецептурный, Exenatide — Рецептурный. США: Dulaglutide — Рецептурный, Exenatide — Рецептурный. These are factual summaries with source and review date on the individual pages.
