Atrial Natriuretic Peptide vs Nesiritide

Atrial Natriuretic Peptide vs Nesiritide — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Atrial Natriuretic Peptide
Cardiovascular / Natriuretic Peptide

Atrial natriuretic peptide (ANP) is a 28-amino acid cardiac hormone secreted by atrial cardiomyocytes in response to increased atrial wall stretch from volume overload or pressure elevation. ANP acts on NPR-A receptors (identical to those targeted by nesiritide/BNP) to produce na...

Nesiritide
Cardiovascular / Natriuretic Peptide

Nesiritide is a recombinant form of human B-type natriuretic peptide (BNP), approved for the intravenous treatment of acutely decompensated heart failure (ADHF) in patients with dyspnea at rest or with minimal activity. Released endogenously by ventricular cardiomyocytes in respo...
