Noradrenalin Kabi (Noradrenaline Tartrate)

Noradrenalin Kabi is a vasopressor used in critical care to support circulatory function during severe hypotension.

• Hypotension: restores arterial pressure and improves organ perfusion in patients with acute low blood pressure.
• Septic shock: counteracts vasodilatory failure, raising systemic vascular resistance to maintain hemodynamic stability.
• Cardiac arrest: provides immediate pressor support during resuscitation efforts to sustain coronary and cerebral perfusion.
• Post‑operative vasoplegia: reverses refractory vasodilation after major surgery, helping to achieve target blood pressure.

• Noradrenaline Tartrate acts as an alpha‑adrenergic receptor agonist, primarily stimulating α1 receptors on vascular smooth muscle. This activation induces vasoconstriction, increasing systemic vascular resistance and arterial pressure. At higher concentrations it also engages β1 receptors, modestly enhancing cardiac contractility and heart rate. The combined effect rapidly elevates blood pressure, supporting perfusion in states of profound hypotension.

Administration of Noradrenalin may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Headache: mild to moderate intensity.
• Tachycardia: increased heart rate.
• Nausea: occasional gastrointestinal discomfort.
• Anxiety: feelings of restlessness.

Serious or Rare Side Effects

• Cardiac arrhythmias: potentially life‑threatening rhythm disturbances.
• Severe hypertension: excessive rise in blood pressure.
• Tissue necrosis: extravasation at the injection site causing local injury.
• Myocardial ischemia: reduced coronary blood flow leading to chest pain.

Clinicians should observe specific precautions when using Noradrenalin to minimize risks and ensure therapeutic benefit.

• Monitor blood pressure continuously: adjust infusion rate to maintain target MAP.
• Assess cardiac function: avoid excessive dosing in patients with ischemic heart disease.
• Use central venous access when possible: reduces risk of extravasation.
• Titrate slowly in septic shock: prevent abrupt hypertension.
• Avoid concurrent use with MAO inhibitors: risk of hypertensive crisis.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Noradrenalin can interact with several agents, altering its efficacy or safety profile.

Major Interactions (Avoid)

• MAO inhibitors: synergistic vasoconstriction may cause severe hypertension.
• Tricyclic antidepressants: additive pressor effects increase risk of hypertensive emergencies.

Moderate Interactions (Monitor Closely)

• Beta‑blockers: may blunt β1‑mediated cardiac stimulation, requiring dose adjustment.
• Calcium channel blockers: combined vasoconstriction can exacerbate hypertension.
• Diuretics: volume depletion may enhance pressor response, necessitating careful monitoring.
