Generic Name: Norepinephrine
Trade Name: Levophed
Action: Adrenergic Agonist
Indications: Hypotension

Decreased Systemic Vascular Resistance

Administration Guidelines:
Usual Dosage Range and Route: 2 to 100 mcg/min IV as titrated to patient response
Standard Concentrations:

Central:
4 mg/250ml
8 mg/250 ml
16 mg/250 ml
64mg/1000ml

Peripheral: N/A*

MICROINFUSION: 4mg/50ml, 16mg/50ml, 50mg/50ml

Special Considerations: *Central line required for administration; in cases of emergency or profound hypotension, norepinephrine may be given peripherally while preparation for central line is underway using the standard concentration of 4 mg / 250 ml.

* Peripheral administration of the 4 mg / 250 ml concentration may be used for short term administration (e.g. pre-transplant and post-op management of labile blood pressure in which a central line is a relative contraindication)

- PA line monitoring of cardiac output, cardiac index, PCWP, CVP, and SVR is encouraged during maintenance infusions.

- Should be used with caution in patients with ischemic heart disease

- Invasive blood pressure monitoring (e.g. a-line) should be considered when centrally administered vasoactive agents are used or when frequent changes in infusion rate are required.

Precautions and Side Effects: - Bradycardia

- Peripheral vasoconstriction, extremity necrosis

- Hypertension

- Oliguria

- Diaphoresis

- Restlessness, nasal congestion
