Noradrenaline Aguettant (Noradrenaline Tartrate)

• Noradrenaline Aguettant, a sympathomimetic vasopressor, is used in conditions that require rapid elevation of systemic vascular resistance and cardiac output.
• Acute hypotension: restores arterial pressure to maintain organ perfusion during sudden drops in blood pressure.
• Septic shock: counteracts vasodilatory failure to improve mean arterial pressure and tissue oxygen delivery.
• Cardiac arrest: provides immediate circulatory support during resuscitation efforts to sustain vital organ flow.
• Post‑operative hemodynamic support: stabilizes blood pressure after major surgery when patients are prone to hypotensive episodes.

• Noradrenaline Tartrate acts as a direct agonist at α1‑adrenergic receptors on vascular smooth muscle, causing vasoconstriction, and at β1‑adrenergic receptors in the heart, increasing contractility and heart rate. These actions are dose‑dependent and occur within seconds after intravenous administration, providing immediate hemodynamic support in critical care settings.

Noradrenaline Aguettant may be associated with a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Headache: mild to moderate pain often occurring shortly after infusion.
• Tachycardia: increased heart rate due to β1‑adrenergic stimulation.
• Nausea: transient gastrointestinal discomfort.
• Anxiety: feelings of restlessness or nervousness.

Serious or Rare Side Effects

• Myocardial ischemia: reduced coronary blood flow leading to chest pain.
• Severe hypertension: excessive rise in blood pressure that may cause vascular injury.
• Tissue necrosis at infusion site: local ischemic injury from extravasation.
• Cardiac arrhythmias: potentially life‑threatening rhythm disturbances.

• When using Noradrenaline Aguettant, clinicians should observe specific precautions to minimise risks and ensure safe administration.
• Dose titration: adjust infusion rate to achieve target blood pressure while avoiding excessive vasoconstriction.
• Cardiac monitoring: continuous ECG and hemodynamic monitoring is required due to potential arrhythmias.
• Peripheral perfusion: monitor extremities for signs of ischemia, especially with high infusion rates.
• Drug compatibility: avoid mixing with solutions containing calcium or bicarbonate that may precipitate.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Noradrenaline Aguettant can interact with several medications, altering its efficacy or increasing adverse effects.

Major Interactions (Avoid)

• Beta‑blockers: may blunt β1‑mediated cardiac effects, reducing pressor response.
• MAO inhibitors: risk of hypertensive crisis when combined with sympathomimetics.
• Tricyclic antidepressants: additive vasoconstriction may cause severe hypertension.

Moderate Interactions (Monitor Closely)

• Vasodilators (nitroglycerin, nitroprusside): may require higher noradrenaline doses.
• Calcium channel blockers: may potentiate hypotensive effects if noradrenaline is tapered.
• Diuretics: volume depletion can enhance vasopressor requirement.
