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.
Survodutide
Survodutide is a dual agonist at the GLP-1 and glucagon receptors. The GLP-1 component mediates glucose-dependent insulin secretion, inhibition of glucagon secretion at high blood glucose and modulation of satiety. The glucagon component raises basal energy expenditure via hepatic and brown adipocyte effects. A fatty-acid side chain enables albumin binding and weekly dosing.

Frequently asked questions
- What is the difference between Lixisenatide and Survodutide?
- Lixisenatide is classified as "Metabolico", while Survodutide is classified as "Metabolico". 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. Survodutide: Synthetic peptide that simultaneously activates the GLP-1 and glucagon receptors. Developed by Boehringer Ingelheim and Zealand Pharma; in phase-3 trials for obesity (SYNCHRONIZE) and MASH. No marketing approval yet. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Lixisenatide or Survodutide?
- The highest available evidence level is "RCT sull'uomo" for Lixisenatide and "RCT sull'uomo" for Survodutide. 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 Survodutide in Germany and the United States?
- Germania: Lixisenatide — Su prescrizione, Survodutide — Non approvato. Stati Uniti: Lixisenatide — Non approvato, Survodutide — Non approvato. These are factual summaries with source and review date on the individual pages.
