Uses of Norepinephrine Drugs

Uses of Norepinephrine Drugs

Norepinephrine also known as noradrenaline is a substance secreted by the body which functions both as a hormone and a neurotransmitter.

Norepinephrine, also known as noradrenaline, is a prevailing prescription that is used for its effect on the heart and blood vessels. It is normally produced in the adrenal medulla of the body. The drug has been approved by the Food and Drug Administration (FDA) for medicinal use since its synthetic production in 1938.

This neurotransmitter is related to N Acetyltyrosine, DL Phenylaline, and ExcitaCor.

Norepinephrine interacts with alpha receptors to cause the restriction of blood vessels thus increasing blood pressure and blood flow to the heart. Their actions with beta receptors result to stimulating the heart to beat faster and pump harder. Small doses of the drug result to dominating beta receptor action while at increasing doses effects with regards to alpha receptors become prevalent. The effects of the drugs to the body is fast but also fades rapidly when not administered thus making it very useful in emergency situations where an immediate response is needed.

Norepinephrine may be used to combat low blood pressure especially when it becomes extremely low. Because of its action to constrict blood vessels, increasing blood pressure to normal levels is expected. Due to this ability, a rise in blood pressure is expected making the drug very efficient in treating situations where blood pressure falls under normal range like circumstances of shock.

Heart attack or cardiac arrest is one of the deadliest instances that a person may face and having no emergency drug to counteract its effects may be fatal. Norepinephrine can also be administered to treat cardiac arrest or heart attack because of its ability to increase blood flow in the coronary arteries and ability to help make the heart pump faster. Using norepinephrine in this case will also help the patient maintain an adequate blood pressure.
