Mechanism of action
Cerebrolysin
Cerebrolysin is a mixture of low-molecular-weight peptides (predominantly below 10 kDa) and free amino acids obtained by enzymatic cleavage of lipid-free porcine brain proteins. The manufacturer and preclinical literature describe a neurotrophic and neuroprotective mode of action said to mimic endogenous neurotrophic factors; cell and animal models have reported effects on neuronal survival, synaptogenesis and anti-apoptotic signalling (including PI3K/Akt). Because it is a complex, incompletely characterised mixture, the precise mechanism in humans remains unclear.
Teduglutid
Teduglutide activates the GLP-2 receptor, promoting growth and regeneration of small-intestinal villi, increasing nutrient and fluid absorption and thereby reducing dependence on parenteral nutrition. The glycine substitution at position 2 makes it resistant to rapid breakdown by DPP-4.

Frequently asked questions
- What is the difference between Cerebrolysin and Teduglutid?
- Cerebrolysin is classified as "Research other", while Teduglutid is classified as "Research other". Cerebrolysin: Cerebrolysin (FPF-1070) is not a single peptide but a porcine-brain-derived preparation of low-molecular-weight peptides and free amino acids, produced by standardised enzymatic proteolysis. It is approved in several countries (including Austria, Russia and parts of Asia) for stroke, dementia and traumatic brain injury, but is not FDA-approved in the United States and not centrally approved by the EMA. Its efficacy is contested: Cochrane systematic reviews found no convincing benefit and flagged possible harm signals. Teduglutid: Teduglutide is a DPP-4-resistant analog of GLP-2 (glucagon-like peptide-2). It promotes growth and function of the intestinal mucosa and is approved for treating short bowel syndrome. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cerebrolysin or Teduglutid?
- The highest available evidence level is "Human RCT" for Cerebrolysin and "Human RCT" for Teduglutid. 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 Cerebrolysin and Teduglutid in Germany and the United States?
- Germany: Cerebrolysin — Unclear, Teduglutid — Prescription. United States: Cerebrolysin — Unapproved, Teduglutid — Prescription. These are factual summaries with source and review date on the individual pages.
