The general function of norepinephrine is to mobilize the brain and body for action. Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the brain, norepinephrine increases arousal and alertness, promotes ...
The action of insulin is counterregulated by glucagon, epinephrine (), norepinephrine (noradrenaline), cortisol, and growth hormone.These counterregulatory hormones—the term is usually used in the plural—raise the level of glucose in the blood by promoting glycogenolysis, gluconeogenesis, ketogenesis, and other catabolic processes.

Norepinephrine, also known as noradrenaline and sold under the brand name Levophed among others, is a medication used to treat people with very low blood pressure. [2] It is the typical medication used in sepsis if low blood pressure does not improve following intravenous fluids . [ 3 ]
Norepinephrine released from locus coeruleus will feedback to inhibit its production, and corticotropin-releasing factor will feedback to inhibit its production, while positively feeding to the locus coeruleus to increase norepinephrine production. [19] The LC's role in cognitive function in relation to stress is complex and multi-modal.

Norepinephrine Epinephrine. A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET).
A norepinephrine and dopamine disinhibitor (NDDI or NDD) is a drug that acts at specific sites to disinhibit downstream norepinephrine and dopamine release in the brain. [ 1 ] Agomelatine , an antidepressant which disinhibits norepinephrine and dopamine release in the frontal cortex by antagonizing 5-HT 2C receptors , [ 2 ] was the first drug ...
Adrenergic nervous system, a part of the autonomic nervous system that uses epinephrine or norepinephrine as its neurotransmitter [3] Regarding proteins : Adrenergic receptor , a receptor type for epinephrine and norepinephrine; subtypes include α 1 , α 2 , β 1 , β 2 , and β 3 receptors
