Meccanismo d'azione
Elamipretide
Elamipretide is a cell-permeable tetrapeptide with alternating aromatic and basic residues that selectively concentrates on cardiolipin — a phospholipid found almost exclusively in the inner mitochondrial membrane that is important for cristae curvature and the organisation of the respiratory-chain complexes. By binding cardiolipin, elamipretide is proposed to stabilise cristae architecture, support electron transport and ATP production, and reduce the formation of reactive oxygen species. These mechanistic models derive largely from cell and animal models and biophysical work; the extent to which they explain clinical efficacy in humans is, given the mixed trial results, a matter of ongoing research.
Sekretin
Secretin binds the Gs-coupled secretin receptor (SCTR) on pancreatic duct cells, opens CFTR chloride channels and triggers secretion of bicarbonate-rich pancreatic fluid and bile flow.

Frequently asked questions
- What is the difference between Elamipretide and Sekretin?
- Elamipretide is classified as "Ricerca (altro)", while Sekretin is classified as "Ricerca (altro)". Elamipretide: Elamipretide (SS-31, MTP-131, formerly Bendavia) is a synthetic, mitochondria-targeting tetrapeptide (sequence D-Arg-Dmt-Lys-Phe-NH2) that binds cardiolipin on the inner mitochondrial membrane and is proposed to stabilise cristae structure and support mitochondrial bioenergetics. It was investigated clinically by Stealth BioTherapeutics across several indications, including primary mitochondrial myopathy, Barth syndrome, heart failure, and dry age-related macular degeneration (geographic atrophy). The trial record is mixed, with several pivotal studies missing their primary endpoints. In September 2025 elamipretide (brand name Forzinity) received accelerated FDA approval in the United States solely for the ultra-rare Barth syndrome; for all other investigated indications it remains investigational and it is not approved as a medicine outside the United States. Sekretin: Secretin is a 27-amino-acid hormone that regulates pancreatic bicarbonate secretion. As ChiRhoStim it is FDA-approved as a diagnostic agent (pancreatic function test, gastrinoma test, secretin-enhanced MRCP). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Elamipretide or Sekretin?
- The highest available evidence level is "RCT sull'uomo" for Elamipretide and "Studio sull'uomo" for Sekretin. 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 Elamipretide and Sekretin in Germany and the United States?
- Germania: Elamipretide — Non approvato, Sekretin — Su prescrizione. Stati Uniti: Elamipretide — Su prescrizione, Sekretin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
