Angiotensin-(1-7) vs Larazotide
An educational, source-based comparison of Angiotensin-(1-7) and Larazotide — how each peptide works, what it's researched for, and what to know before going deeper.
Counter-regulatory peptide of the renin-angiotensin system.
A heptapeptide of the renin-angiotensin system that acts on Mas receptors. Research demonstrates counter-regulatory effects to angiotensin II, promoting vasodilation, anti-inflammatory signaling, and anti-fibrotic effects in cardiovascular and renal tissues.
- Pulmonary hypertension and fibrosis
- Heart failure with preserved ejection fraction
- Acute lung injury and ARDS
- Diabetic nephropathy
- • Investigational; not FDA-approved.
- • Interaction with ACE inhibitors and ARBs requires careful study design.
An octapeptide zonulin antagonist that helps maintain intestinal tight junction integrity, reducing paracellular permeability triggered by gluten in celiac disease.
- Celiac disease (Phase 3 completed)
- Intestinal barrier function ('leaky gut' research)
- Environmental enteropathy
- • Not yet FDA-approved.
- • Investigational; physician oversight required.
Trial-evidence rating
Educational grade reflecting how many peer-reviewed studies and FDA actions we cite for each peptide. Not a clinical recommendation.

FDA-approved with published clinical trial data.
Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Angiotensin-(1-7) | Angiotensin-(1-7) as a therapeutic in lung disease | American Journal of Respiratory and Critical Care Medicine | 2020 | Demonstrated protective effects in acute lung injury and pulmonary fibrosis models. |
