Medically reviewed by Drugs.com. Last updated on Jul 17, 2020.

Pronunciation

(ni SIR i tide)

Index Terms

  • B-type Natriuretic Peptide (Human)
  • hBNP
  • Natriuretic Peptide

Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling. [DSC] = Discontinued product

Solution Reconstituted, Intravenous:

Natrecor: 1.5 mg (1 ea [DSC])

Brand Names: U.S.

  • Natrecor [DSC]

Pharmacologic Category

  • Natriuretic Peptide, B-Type, Human

Pharmacology

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.

Distribution

Vss: 0.19 L/kg

Metabolism

Proteolytic cleavage by vascular endopeptidases and proteolysis following binding to the membrane bound natriuretic peptide (NPR-C) and cellular internalization

Excretion

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

Half-Life Elimination

Initial (distribution) ~2 minutes; Terminal: ~18 minutes

Use: Labeled Indications

Acutely decompensated heart failure (HF): Treatment of acutely decompensated heart failure (HF) with dyspnea at rest or with minimal activity

Contraindications

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

Dosing: Adult

Note: Natrecor is no longer available in the US.

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.

Dosing: Geriatric

Refer to adult dosing. Older individuals may be more sensitive to the effect of nesiritide than younger patients.

Dosing: Pediatric

Note: Natrecor is no longer available in the US.

Heart failure, decompensated: Limited data available: Note: Nesiritide is not recommended for first-line therapy; may be considered when other treatment options have failed to lower central venous pressure (CVP) (ISHLT [Kirk 2014]): Infants, Children, and Adolescents:

Continuous IV infusion: Initial bolus (optional): 1 mcg/kg, followed by continuous infusion of 0.01 mcg/kg/minute; titrate by 0.005 mcg/kg/minute based on clinical response; manufacturer's labeling recommends titrating not more frequently than every 3 hours in adults; usual reported dose range: 0.005 to 0.02 mcg/kg/minute; maximum infusion rate: 0.03 mcg/kg/minute (Jefferies 2007; Mahle 2005). Dosing is based on a retrospective study and an observational study. The retrospective study included 30 pediatric patients (age: median: 4.6 months, range: 5 days to 16.7 years) with heart failure and worsening symptoms despite receiving conventional therapy (eg, inotropic and diuretic therapy). Most patients (80%) received a bolus dose of 1 mcg/kg and all patients received a continuous infusion of 0.005 to 0.02 mcg/kg/minute. Fluid balance and urine output significantly increased after 24 hours of treatment. Minimal effects on blood pressure were reported during infusion; however, one patient required discontinuation due to hypotension (Mahle 2005). Similar results were reported in the observational study of 63 patients (age: 11.97 ± 4.76 years; range: 0.01 to 20.5 years); patients were treated with an initial infusion rate of 0.01 mcg/kg/minute (without bolus dose); if necessary based on clinical response, rate was titrated by 0.005 mcg/kg/minute to a maximum rate of 0.03 mcg/kg/minute. Urine output improved on days 1 and 3 of therapy and only two patients required discontinuation due to hypotension (Jefferies 2007). If hypotension occurs during nesiritide administration, consider reducing dose or discontinuing infusion; if necessary, other measures to support blood pressure should be initiated.

Reconstitution

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.

Administration

IV: 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.

Storage

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.

Warnings/Precautions

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.

Disease-related concerns:

• 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.

Other warnings/precautions:

• Prolonged infusions: Use caution with prolonged infusions; limited experience with infusions >96 hours.

Monitoring Parameters

Blood pressure, hemodynamic responses (PCWP, RAP, CI), BUN, creatinine; urine output; consult individual institutional policies and procedures

Pregnancy Considerations

Adverse events were not observed in an animal reproduction study.

Data in humans are inadequate to make recommendations for use in pregnancy (ESC [Regitz-Zagrosek 2018]).
