Механизм действия
Lixisenatide
Lixisenatide is a 44-amino-acid peptide based on exendin-4 (see exenatide) with six additional lysine residues at the C-terminus. This modification increases stability against DPP-4 degradation. The short half-life (~3 hours) and plasma peak around mealtime explain the predominantly prandial effect — stronger postprandial glucose action, weaker fasting glucose effect than weekly GLP-1 RAs.
Petrelintide
As an amylin analogue, petrelintide acts through amylin receptors, promoting satiety and slowed gastric emptying — a satiety pathway independent of the GLP-1 axis.

Frequently asked questions
- What is the difference between Lixisenatide and Petrelintide?
- Lixisenatide is classified as "Метаболизм", while Petrelintide is classified as "Метаболизм". Lixisenatide: Synthetic exendin-4 analog with a C-terminal lysine extension. Prandial GLP-1 RA focused on postprandial glucose. FDA-approved 2016 as Adlyxin; EMA-approved 2013 as Lyxumia. Sanofi discontinued US distribution in 2023. Petrelintide: Petrelintide is a long-acting amylin analogue (Zealand Pharma, with Roche) for once-weekly subcutaneous use — developed for weight management with a focus on strong tolerability. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Lixisenatide or Petrelintide?
- The highest available evidence level is "РКИ на людях" for Lixisenatide and "РКИ на людях" for Petrelintide. 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 Lixisenatide and Petrelintide in Germany and the United States?
- Германия: Lixisenatide — Рецептурный, Petrelintide — Не одобрено. США: Lixisenatide — Не одобрено, Petrelintide — Не одобрено. These are factual summaries with source and review date on the individual pages.
