What is norepinephrine (noradrenaline) and what does it do in the body?
Norepinephrine (also called noradrenaline) is a neurotransmitter and hormone that helps regulate alertness, blood pressure, and blood flow. It acts mainly by stimulating adrenergic receptors in the nervous system and the cardiovascular system, which can increase heart activity and tighten blood vessels.
How is norepinephrine used as a medicine?
In clinical settings, norepinephrine is used as a vasopressor to help treat dangerously low blood pressure (shock). By increasing vascular tone and supporting circulation, it can improve perfusion to vital organs.
What conditions are norepinephrine treatments for?
Clinicians most often use norepinephrine in shock states where blood pressure is critically low, such as:
- Septic shock
- Other forms of shock involving hypotension despite initial fluid/resuscitation measures
What are common side effects and risks?
Because norepinephrine strongly affects blood vessels and heart function, major risks include:
- Reduced blood flow to extremities or organs (from excessive vasoconstriction)
- Heart rhythm problems
- Tissue injury if the medication leaks outside the vein during IV administration (extravasation risk)
How is norepinephrine typically given?
Norepinephrine is generally administered intravenously with careful blood-pressure and perfusion monitoring. Dosing is usually titrated to the patient’s blood pressure response and overall clinical status.
Are there alternatives to norepinephrine?
Yes. Depending on the type of shock and patient response, clinicians may use other vasopressors (for example, agents that primarily work through different adrenergic pathways) or adjust supportive treatments such as fluids and treating the underlying cause of shock.
