Nesiritide is the recombinant form of the 32 amino acid human B-type natriuretic peptide, which is normally produced by the ventricular myocardium. It is an agonist of natriuretic peptide receptors (NPRs), with Kd values of 7.3 and 13 pM for NPR-A and NPR
Nesiritide, a 32-amino acid natriuretic peptide and recombinant form of human brain natriuretic peptide, enhances vasorelaxation ex vivo in porcine hearts from an acute coronary occlusion model when given as a 2 µg/kg bolus dose followed by a 0.01 µg/kg per minute infusion, facilitated by the calcium ionophore A23187. Formulations containing nesiritide have been utilized in managing congestive heart failure.
