Larazotide Acetate- Summary
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- Larazotide acetate is an 8-amino acid peptide (Gly-Gly-Val-Leu-Val-Gln-Pro-Gly) derived from Zonula Occludens Toxin (ZOT) of Vibrio cholerae. It paradoxically acts as a ZOT antagonist to close tight junctions and reduce intestinal permeability ('leaky gut'). It is the most advanced clinical compound targeting gut permeability directly.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Local gut action; minimal systemic exposure
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
- Oral

- 3x daily
- Key Benefits
- Potent analgesia superior to morphine on a per-weight basis
- May reduce perception of fatigue in high-intensity activity
- Longer-lasting than endogenous opioids due to D-amino acid substitution
- Research tool for mu-opioid receptor pharmacology
- Potential therapeutic application in refractory pain
- Directly reduces intestinal tight junction permeability
- Clinical efficacy in celiac disease (Phase 3 trials)
- Reduces systemic inflammation from gut permeability
- Targets root cause of leaky gut (Zonulin pathway)
- Local gut action without systemic absorption
- Potential application in IBS, IBD, autoimmune conditions
