nesiritide

Natrecor

Pharmacologic class: Human B-type natriuretic peptide

Therapeutic class: Vasodilator

Pregnancy risk category C

Action

Binds to receptors on vascular smooth muscle and endothelial cells, causing smooth muscle relaxation and vasodilation. As a result, systemic and pulmonary pressures decrease and diuresis occurs.

Availability

Injection: 1.5 mg in single-use vials

Indications and dosages

Acutely decompensated heart failure in patients who have dyspnea at rest or with minimal activity

Adults: 2 mcg/kg I.V. bolus, followed by continuous I.V. infusion of 0.01 mcg/kg/minute

Contraindications

• Hypersensitivity to drug or its components

• Systolic pressure below 90 mm Hg

• Primary therapy for cardiogenic shock

Precautions

Use cautiously in:

• restrictive or obstructive cardiomyopathy, constrictive pericarditis, pericardial tamponade, renal dysfunction, hypotension

• pregnant or breastfeeding patients.

Administration

Know that nesiritide is a high-alert drug.

• For I.V. use, prime tubing before connecting to patient. Withdraw bolus and infuse over 60 seconds into I.V. port of tubing. Follow immediately with constant infusion delivering 0.01 mcg/kg/minute.

• Know that drug should be mixed and infused in dextrose 5% in water, normal saline solution, or dextrose in half-normal saline solution.

Don't mix with other drug solutions. Always administer through separate line.

• Know that nesiritide therapy beyond 48 hours has not been studied.

Adverse reactions

CNS: dizziness, headache, insomnia, anxiety

CV: hypotension, angina pectoris, bradycardia, ventricular extrasystole, ventricular tachycardia

GI: nausea, vomiting, abdominal pain

Musculoskeletal: leg cramps, back pain

Respiratory: cough, hemoptysis, apnea

Other: injection site reactions

Interactions

Drug-drug. Angiotensin-converting enzyme inhibitors, nitrates: increased hypotension

Bumetanide, enalaprilat, ethacrynate sodium, furosemide, heparin, hydralazine, insulin: physical and chemical incompatibility with nesiritide

Drug-diagnostic tests. Hematocrit, hemoglobin: decreased values

Patient monitoring

• Monitor vital signs and pulmonary artery wedge pressure continuously during and for several hours after infusion.

• Assess cardiovascular status closely.

Patient teaching

• Tell patient he'll be monitored closely during and for several hours after infusion.

• Inform patient that drug may cause serious adverse effects. Reassure him that he'll receive appropriate interventions to relieve symptoms.

• Instruct patient to report chest pain, dizziness, palpitations, and other uncomfortable symptoms.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs and tests mentioned above.

nesiritide

a vasodilator used to treat acutely decompensated congestive heart failure.

Natrecor

A recombinant brain (B-type) natriuretic peptide given intraveinously to patients with acutely decompensated heart failure and dyspnoea at rest. Natrecor relaxes blood vessels, increases natriuresis and diuresis, and decreases neurohormones. 

Adverse effects
Hypotension, ventricular tachycardia, headache, nausea, back pain, decreased renal function. It has been linked to increased mortality or renal damage; it is to be used only on severely ill patients.

nesiritide

A commercial form of recombinant human natriuretic peptide that has been promoted in the USA. It was approved by the FDA for the treatment of acute, decompensated congestive heart failure. There were reports in mid-2005 of adverse effects on survival and kidney function.

La adecuada seleccion de los pacientes que requieren manejo inotropico es fundamental (14), los diureticos son de utilidad para el manejo de los sintomas de congestion; sin embargo, no disminuyen la mortalidad (15-16) y los vasodilatadores son de gran ayuda por su efecto sobre las resistencias perifericas que caracteristicamente se encuentran elevadas en el perfil hemodinamico de los pacientes con falla cardiaca, la nitroglicerina es el vasodilatador mas utilizado en nuestro medio, sin embargo existen otras alternativas como el nesiritide aunque se discute su modo de administracion ideal (dosis, administracion sin bolo) y su efecto adverso sobre la funcion renal (17-19).
