Term
Norepinephrine Bitartrate (Levophed)
Definition

Class: Sympathomimetic, vasopressor.

MOI: Potent alpha-agonist resulting in intense peripheral vasoconstriction, positive chronotropic and increased inotropic effect (from 10% beta effect) with increased cardiac output. Alpha-adrenergic activity resulting in peripheral vasoconstriion and beta-adrenergic activity leading to inotropic stimulation of the heart and coronary artery vasodilation. 

Indications: Cardiogenic shock, unresponsive to fluid resuscitation, significant hypontensive (<70mmhg) states. 

Contraindications: Hypotensive patients with hypovolemia, pregnancy (relative CI).

Side effects: HA, anxiety, dizziness, restlessness, dyspnea, bradycardia, hypertension, dysrhythmias, CP, peripheral cyanosis, cardiac arrest, N&V, urinary retention, renal failure, decreased blood flow to the GI tract, kidneys, skeletal muscle, and skin, tissue necrosis from extravasation. 

Drug interations: Can be deactivated by alkaline solutions. Sympathomimetic and phosphodiesterase inhibitors may exacerbate dysrhythmias. Bretylium may potentiate the effects of catecholamines.

How supplied: 1mg/mL vials.

Dosage and administration: Adult: Dilute 8mg in 500mL or 4mg in 250mL D5W (16ug/mL). Infuse by IV piggyback at 0.1-0.5ug/kg/min titrated to response (average dose for a 70kg patient is 7-35ug/min). Peds: Begin at 0.1-2ug/kg/min IV infusion, adjust rate to achieve desired in change in B/P and systemic perfusion. Titrated to patient response. 

Duration of action: Onset: 1-3 minutes. Peak: Variable. Duration: 5-10 minutes and last only 1 minute after infusion d/c.

Special considerations: Pregnancy safety: Category C. May cause fetal anoxia when used in pregnancy. Infuse norepinephrine through a large, stable vein to avoid extravasation and tissue necrosis. Often used with low-dose dopamine to spare decreased renal and mesenteric blood flow. Drug or poison induced hypotension may require higher doses to achieve adequate perfusion.
