The primary use of Norepinephrine is to manage severe hypotension (low blood pressure), such as in septic shock or during anaesthesia. It falls under the category of vasopressors.
Additionally, it can also be used during cardiopulmonary resuscitation to help restore cardiac function. In regional anaesthesia, Norepinephrine is added to local anaesthetics to prolong the duration of anaesthesia and reduce bleeding.

Norepinephrine is a vital catecholamine in the human body.
It works by stimulating alpha- and beta-adrenergic receptors, which help regulate the body's "fight or flight" response, influencing stress reactions and maintaining cardiovascular function.
