Class: Vasodilating Agents, Miscellaneous
VA Class: CV900
Chemical Name: Natriuretic factor-32 (human brain clone λhBNP57)
Molecular Formula: C143H244N50O42S4

Introduction
Vasodilator; a biosynthetic (recombinant DNA origin) form of human B-type natriuretic peptide (BNP).
Uses for Nesiritide
Acute Decompensated Heart Failure
Treatment of acutely decompensated heart failure in patients with dyspnea at rest or with minimal activity.
Evidence demonstrating improved outcomes with IV vasodilator therapy in hospitalized patients with heart failure is lacking.
May be considered an adjunct to diuretic therapy for relief of dyspnea in patients hospitalized for acutely decompensated heart failure who do not have symptomatic hypotension.
FDA-approved labeling for treatment of dyspnea in patients with acutely decompensated heart failure based on clinical trials showing reductions in pulmonary capillary wedge pressure (PCWP) and improvement in dyspnea when assessed 3 hours after initiation of the IV infusion. A subsequent placebo-controlled trial in >7000 patients (ASCEND-HF) failed to show meaningful improvement in dyspnea at 6 or 24 hours or meaningful short-term reductions in rates of death or rehospitalization for heart failure when nesiritide was used in conjunction with standard therapy.
Some clinicians state that routine use cannot be recommended in the broad population of patients with acutely decompensated heart failure.
Use of intermittent, serial, or scheduled repetitive infusions in an outpatient setting for treatment of severe decompensated heart failure not recommended. A randomized, placebo-controlled trial failed to establish efficacy of serial outpatient nesiritide infusions for treatment of severe heart failure.
Manufacturer recommends strictly limiting use to patients with acutely decompensated heart failure whose manifestations warrant hospitalization or management in emergency department.
Manufacturer does not recommend use as replacement therapy for diuretics, to improve renal function, and/or to enhance diuresis. (See Renal Effects under Cautions.)
Nesiritide Dosage and Administration
General
Administer only in settings where BP can be closely monitored and hypotension treated aggressively.
Concomitant use of other cardiovascular agents including IV nitroglycerin, but excluding certain IV vasodilators (e.g., sodium nitroprusside, milrinone) and IV ACE inhibitors, was allowed in clinical studies.
Administration
Administer IV loading dose followed by continuous IV infusion.
IV Administration
For solution and drug compatibility information, see Compatibility under Stability.
Reconstituted solutions contain no preservatives; solutions preferably should be prepared immediately before use.
