Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Solution Reconstituted, Intravenous:
Natrecor: 1.5 mg (1 ea)
Brand Names: U.S.
- Natriuretic Peptide, B-Type, Human
Binds to guanylate cyclase receptor on vascular smooth muscle and endothelial cells, increasing intracellular cyclic GMP, resulting in smooth muscle cell relaxation. Has been shown to produce dose-dependent reductions in pulmonary capillary wedge pressure (PCWP) and systemic arterial pressure.
Vss: 0.19 L/kg
Proteolytic cleavage by vascular endopeptidases and proteolysis following binding to the membrane bound natriuretic peptide (NPR-C) and cellular internalization
Primarily eliminated by metabolism; also excreted in the urine
Onset of Action
PCWP reduction: 15 minutes (60% of 3-hour effect achieved within this time period); Peak effect: Within 1 hour
Duration of Action
>60 minutes (up to several hours) for systolic blood pressure; hemodynamic effects persist longer than serum half-life would predict
Initial (distribution) ~2 minutes; Terminal: ~18 minutes
Use: Labeled Indications
Treatment of acutely decompensated heart failure (HF) with dyspnea at rest or with minimal activity
Hypersensitivity to natriuretic peptide or any component of the formulation; cardiogenic shock (when used as primary therapy); hypotension (persistent systolic blood pressure <100 mm Hg) prior to therapy
Acute decompensated heart failure: IV: Initial: 2 mcg/kg (bolus optional); followed by continuous infusion at 0.01 mcg/kg/minute. Note: Should not be initiated at a dosage higher than initial recommended dose. There is limited experience with increasing the dose >0.01 mcg/kg/minute; in one trial, a limited number of patients received higher doses that were increased no faster than every 3 hours by 0.005 mcg/kg/minute (preceded by a bolus of 1 mcg/kg), up to a maximum of 0.03 mcg/kg/minute. Increases beyond the initial infusion rate should be limited to selected patients and accompanied by close hemodynamic and renal function monitoring.
Patients experiencing hypotension during the infusion: Infusion dose should be reduced or discontinued. Other measures to support blood pressure should be initiated (eg, IV fluids, Trendelenburg position). Hypotension may be prolonged (up to hours); once patient is stabilized, may attempt to restart at a lower dose (reduce previous infusion dose by 30% and omit bolus).
Maximum dosing weight: According to the manufacturer, the PRECEDENT Trial capped dosing weight at 160 kg and the VMAC Trial capped dosing weight at 175 kg. There are no specific guidelines on maximum dosing weight and clinical judgment should be used.
Refer to adult dosing.
Dosing: Renal Impairment
No dosage adjustment necessary. Use cautiously in patients with renal impairment or those patients who rely on the renin-angiotensin-aldosterone system for renal perfusion. Monitor renal function closely.
Dosing: Hepatic Impairment
No dosage adjustment provided in manufacturer’s labeling.
Reconstitute 1.5 mg vial with 5 mL of diluent removed from a prefilled 250 mL plastic IV bag (compatible with D5W, D51/2NS, D51/4NS, NS). Do not shake vial to dissolve (roll gently). Withdraw entire contents of vial and add to 250 mL IV bag. Invert several times to mix. Resultant concentration of solution is ∼6 mcg/mL.
Do not administer through a heparin-coated catheter (concurrent administration of heparin via a separate catheter is acceptable, per manufacturer).
Prime IV tubing with 5 mL of infusion prior to connection with vascular access port and prior to administering bolus or starting the infusion. Withdraw bolus from the prepared infusion bag and administer over 60 seconds. Begin infusion immediately following administration of the bolus.
See Trissel’s IV Compatibility Database
Vials may be stored below 25°C (77°F); do not freeze. Protect from light. Following reconstitution, vials are stable at 2°C to 25°C (36°F to 77°F) for up to 24 hours. Use reconstituted solution within 24 hours.

Concerns related to adverse effects:
• Anaphylactic/hypersensitivity reactions: Serious anaphylactic or hypersensitivity reactions may occur following administration; obtain careful history and use caution in patients with previous hypersensitivity to other recombinant peptides; nesiritide prepared through recombinant technology using E. coli.
• Hypotension: May cause hypotension; administer in clinical situations when blood pressure may be closely monitored. Effects may be additive with other agents capable of causing hypotension. Hypotensive effects may last for several hours.
• Renal effects: May be associated with development of azotemia; use caution in patients with renal impairment or in patients where renal perfusion is dependent on renin-angiotensin-aldosterone system (eg, severe heart failure); avoid initiation at doses higher than recommended; increases in serum creatinine may occur at an elevated rate.
• Cardiovascular disease: Should not be used in patients with low cardiac filling pressures, or in patients with conditions which depend on venous return including significant valvular stenosis, restrictive or obstructive cardiomyopathy, constrictive pericarditis, and pericardial tamponade.
• Renal impairment: Use with caution in patients with renal impairment.
• Prolonged infusions: Use caution with prolonged infusions; limited experience with infusions >96 hours.

Pregnancy Risk Factor
Adverse events were not observed in an animal reproduction study. Nesiritide is a recombinant B-type natriuretic peptide (rhBNP). BNP and NT-proBNP (which has been used as a marker of BNP), are endogenous peptides and NT-proBNP is measurable in the umbilical cord serum of normal pregnancies. Information related to the administration of nesiritide during pregnancy has not been located.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache, nausea, or back pain. Have patient report immediately to prescriber signs of kidney problems (urinary retention, hematuria, change in amount of urine passed, or weight gain), severe dizziness, or passing out (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
