Nesiritide


Full Prescribing Info
Dosage/Direction for Use

Intravenous
Acutely decompensated heart failure
Adult: Initial loading dose: 2 mcg/kg by IV inj over 1 minute, followed immediately by a maintenance infusion of 0.01 mcg/kg/minute. Duration of treatment: At least 24 hr to ≥48 hr.
Contraindications
Primary therapy for cardiogenic shock; systolic BP <90 mm Hg.
Special Precautions
Not recommended in patients with known or suspected low cardiac filling pressures or in whom vasodilating agents are inappropriate (e.g. significant valvular stenosis, restrictive or obstructive cardiomyopathy, constrictive pericarditis, pericardial tamponade). Not recommended in any other conditions in which cardiac output depends on venous return. Pregnancy, lactation, children. Monitor BP closely during admin. Stop or reduce dose and general supportive measures instituted if hypotension occurs during infusion.
Adverse Reactions
Hypotension, dizziness, headache, nausea, vomiting, abdominal pain, back pain, angina pectoris, insomnia, anxiety, renal function impairment.
Overdosage
Symptoms: Excessive hypotension. Management: Reduce dose or discontinue drug. Treatment is supportive (e.g. IV fluids, changes in body position). Hypotension may persist for a few hr.
Drug Interactions
Increased risk of hypotension with drugs that may decrease BP.
Action
Nesiritide, a biosynthetic form of human B-type natriuretic peptide (BNP), is manufactured from E. coli using recombinant DNA technology. It is structurally and pharmacologically identical to endogenous BNP, which is the main natriuretic peptide responsible for normal fluid and sodium homeostasis maintenance in heart failure patients. Binding of endogenous BNP to the particulate guanylate cyclase receptor of vascular smooth muscle and endothelial cells increases cyclic guanosine-3', 5'-monophosphate (cGMP), which relaxes smooth muscle cells and causes arterial and venous dilation. It also produces dose-dependent reductions in pulmonary capillary wedge pressure and systemic arterial pressure in heart failure patients.
Excretion: Biphasic elimination; terminal elimination half life: 18 minutes. Removed from the circulation in 3 ways, in order of decreasing importance: Cellular uptake; proteolytic cleavage by endopeptidases and kidney excretion.
Storage
Intravenous: Store below 25°C, do not freeze and protect from light. Reconstituted vials may be stored at 2-25°C (36-77°F) for up to 24 hr.
ATC Classification
C01DX19 - nesiritide ; Belongs to the class of other vasodilators used in cardiac diseases.
