Cosyntropin (Cortrosyn) vs Nesiritide (Natrecor)
An educational, source-based comparison of Cosyntropin (Cortrosyn) and Nesiritide (Natrecor) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic peptide containing the first 24 amino acids of ACTH — retains full corticotropic activity. Stimulates adrenal cortisol release for diagnostic testing.
- Primary and secondary adrenal insufficiency diagnosis
- • FDA-approved.
- • Single diagnostic dose; very well tolerated.
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.
