Norepinephrine Introduction
Norepinephrine is a potent catecholamine neurotransmitter that can be found in both the peripheral and central nervous systems. It acts as a hormone and can affect a variety of body systems, such as the cardiovascular and respiratory systems. It is involved in the fight or flight response and is essential for maintaining normal function in these systems.Uses For Norepinephrine
Norepinephrine is commonly used to treat hypotension (low blood pressure). It is also used to help treat cardiac arrest, heart failure, respiratory failure, septic shock, and hypotension associated with anesthesia. It is also used to increase cerebral blood flow in cases of brain injury.Mechanism of Action
The primary action of norepinephrine is to cause vasoconstriction, which helps to maintain blood pressure by increasing the strength of arteries and veins. This vasoconstriction leads to increased blood pressure and improved performance of peripheral organs. Additionally, norepinephrine increases the heart rate and contractility, which helps to improve the blood flow to vital organs.How Long Does It Take To Work?
When given intravenously, norepinephrine begins to work almost immediately. The effects can be seen within minutes of administration.Absorption
Norepinephrine is rapidly absorbed after administration. Its effects depend on the mode of administration (total dose, rate, route, etc.)Route of Elimination

Norepinephrine should be administered by a health care professional in a monitored setting. The dosage depends on several factors, such as the patient’s age, weight, and medical condition. A typical adult dose is 2-3 mcg/min, and this dose can be titrated according to the patient’s response.Administration
