What is the Origin of Larazotide Acetate?

The term is a pharmaceutical name for a synthetic peptide compound. "Larazotide" is the non-proprietary name given to the active drug substance, a short, eight-amino-acid peptide. "Acetate" refers to the salt form used for formulation stability. Its development stems from research into the pathology of increased intestinal permeability and the discovery of zonulin as a key mediator of tight junction function in the early 2000s.

What is the Mechanism of Larazotide Acetate?

Larazotide Acetate exerts its function by competitively binding to the Pro-tease-Activated Receptor 2 (PAR2) on the surface of intestinal epithelial cells, which is the same receptor site that zonulin activates. By occupying this receptor, larazotide prevents zonulin from initiating the intracellular signaling cascade that leads to the disassembly of the tight junction complex. This blockade maintains the structural integrity of the epithelial barrier, thereby reducing pathological intestinal permeability and minimizing the subsequent systemic immune and inflammatory responses.

Larazotide Acetate

Meaning

Larazotide Acetate is an investigational synthetic peptide that functions as a tight junction regulator, currently studied for its potential to reduce pathological intestinal permeability, a condition often clinically referred to as “leaky gut.” It operates as a competitive inhibitor of zonulin, a key protein that modulates the paracellular pathway between epithelial cells in the small intestine. By stabilizing the tight junctions, this agent aims to reduce the inappropriate passage of undigested food fragments, toxins, and microbial products into the systemic circulation. Clinically, it has been primarily investigated as an adjunct therapy for Celiac Disease to mitigate the gluten-induced mucosal damage and reduce symptoms.
