Nesiritide (Natrecor) vs Vasopressin (Vasostrict)
An educational, source-based comparison of Nesiritide (Natrecor) and Vasopressin (Vasostrict) — how each peptide works, what it's researched for, and what to know before going deeper.
Recombinant BNP for acute decompensated heart failure.
Recombinant human B-type natriuretic peptide that binds natriuretic peptide receptors to cause vasodilation, natriuresis, and reduction of preload/afterload in decompensated heart failure.
- Acute decompensated heart failure
- • FDA-approved.
- • Hypotension common; renal monitoring needed.
Endogenous nonapeptide that activates V1 vascular receptors to cause vasoconstriction and V2 renal receptors for water reabsorption. Used to raise blood pressure in catecholamine-resistant shock.
- Septic shock
- Cardiac arrest (historical)
- Diabetes insipidus
- • FDA-approved.
- • Ischemic complications possible at high doses.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Nesiritide (Natrecor) | ASCEND-HF trial | NEJM | 2011 | Modest dyspnea improvement; no mortality benefit. |
| Vasopressin (Vasostrict) | VASST trial | NEJM | 2008 | Vasopressin added to norepinephrine did not reduce mortality overall but benefited less severe septic shock. |
