This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.

Background and Date of Approval

Noradrenaline was initially approved by the United States Food and Drug Administration (FDA) on  April 6, 1948.

Mechanism of Action of undefined

Noradrenaline acts as a neurotransmitter and hormone. It binds to adrenergic receptors on target cells, particularly α1 and α2 adrenergic receptors, leading to vasoconstriction, increased heart rate, and enhanced cardiac contractility. This results in elevated blood pressure and improved perfusion in critical situations. Additionally, its effects contribute to the "fight or flight" response, preparing the body for physical exertion during stress.

Uses of undefined

Noradrenaline, a vasopressor medication, manages various critical medical situations. It elevates blood pressure in acute hypotension, shock (including septic and cardiogenic shock), and cardiac arrest. Additionally, this medication aids in treating bradycardia and anaphylactic shock and enhancing regional anesthesia. 

undefined Drug administaration and Dosage available

Noradrenaline is primarily administered intravenously (IV). It's typically given as a continuous infusion through a dedicated IV line under the supervision of trained medical personnel. The IV route allows for precise control of the medication's effects and rapid dosage adjustment in critical situations. This medication requires careful monitoring of vital signs and the patient's response to ensure its safety and efficacy.

Warnings, Precautions and Side Effects of undefined


Rapid or excessive administration of Noradrenaline can lead to a dangerous increase in blood pressure, potentially causing hypertensive crisis, which can result in stroke, heart attack, or other cardiovascular complications. The vasoconstrictive effects of this medication can reduce blood flow to organs or extremities, leading to tissue ischemia or damage. Incorrect IV insertion or monitoring can result in extravasation, where this medication leaks from the IV site into surrounding tissues, causing severe local tissue damage. Its effects on pulmonary blood vessels can lead to increased pulmonary artery pressure, potentially worsening lung conditions.


Noradrenalin administration should be slow to avoid sudden spikes in blood pressure that can be harmful. Keep an eye on the heart rhythm to catch any irregularities early on. Be careful with the dosage, as too much can reduce blood flow to important areas. If someone has lung problems, be extra cautious, as this medication can affect their condition. Dose adjustment is required for different groups, like children and the elderly, as they may need different amounts. Avoid mixing this medication with certain medicines, like nonselective MAOIs, to prevent serious problems. If someone is pregnant, carefully weigh the risks and benefits with a healthcare provider. These precautions are like safety guidelines that help prevent complications and ensure they work well for patients.

Side Effects

Noradrenaline use can lead to a range of potential side effects. Common effects include increased heart rate, elevated blood pressure, headaches, nervousness, nausea, and pale skin. Serious adverse reactions encompass hypertensive crises, arrhythmias, tissue ischemia, and possible extravasation at the infusion site. 

Word Of Advice

There are important steps to follow when using Noradrenaline for safety. Patients require close monitoring by healthcare professionals while taking this medication. In some cases, dose adjustment is required based on the person's age and how they react. Patients should check closely things like heart rate, blood pressure, and how their body responds. Be aware of potentially serious effects like high blood pressure or heart rhythm problems. Take care when putting the IV line in and avoid leaks. Patients should be aware of any side effects and contact their doctor if they face any difficulty during treatment.
