Norepinephrine, also known as noradrenaline, is a
intravenous fluids.[3] It is the same molecule as the hormone and neurotransmitter norepinephrine.[2] It is given by slow injection into a vein.[2]
Common side effects include headache, slow heart rate, and
alpha adrenergic receptors.[2]
Norepinephrine was discovered in 1946 and was approved for medical use in the United States in 1950.generic medication.[2]
Medical uses
Norepinephrine is used mainly as a sympathomimetic drug to treat people in vasodilatory shock states such as septic shock and neurogenic shock, while showing fewer adverse side-effects compared to dopamine treatment.[5][6]
Mechanism of action
It stimulates
peripheral vascular resistance and resulted in increased blood pressure. This effect also reduces the blood supply to gastrointestinal tract and kidneys. Norepinephrine acts on beta-1 adrenergic receptors, causing increase in heart rate and cardiac output.[7] However, the elevation in heart rate is only transient, as baroreceptor response to the rise in blood pressure as well as enhanced vagal tone ultimately result in a sustained decrease in heart rate.[8] Norepinephrine acts more on alpha receptors than the beta receptors.[9]
