The 41 pages that link to Norepinephrine, each with the reason it gives.

• Autonomic nervous systemRelated: Most sympathetic postganglionic neurons use it to influence target organs.

• DopamineCompared with: It shares chemical ancestry with dopamine but has distinct signaling roles.

• AcetylcholineCompared with: Many sympathetic target organs use norepinephrine rather than acetylcholine as their postganglionic transmitter.

• Sympathetic nervous systemRelated: Most sympathetic postganglionic neurons use it to signal their target organs.

• SerotoninCompared with: It is another monoamine signaling system often compared with serotonin in mood research.

• VasoconstrictionRelated: It commonly produces vasoconstriction through vascular alpha-adrenergic receptors.

• CatecholamineBroader topic: It acts as a neurotransmitter in the brain and a transmitter and hormone in the body.

• AmphetamineRelated: Increased norepinephrine signaling helps explain amphetamine’s effects on wakefulness and attention.

• ArousalRelated: Norepinephrine links brain activation with heightened attention and bodily readiness.

• EpinephrineRelated: It is epinephrine’s close biochemical relative and a major adrenal signaling partner.

• Norepinephrine transporterRelated: NET recognizes norepinephrine as its principal substrate and removes it from synapses.

• Septic shockRelated: It is the recommended first-line vasopressor for persistent septic shock hypotension.

• Adrenal medullaRelated: The medulla secretes it alongside epinephrine, though in smaller amounts.

• BupropionRelated: Bupropion’s inhibition of norepinephrine reuptake increases its signaling.

• Opioid withdrawalRelated: Excess noradrenergic activity helps explain sweating, agitation, and rapid heartbeat.

• PheochromocytomaRelated: Its excess can sharply raise blood pressure during tumor attacks.

• VasopressorBroader topic: It is commonly used as the first-line vasopressor for septic shock.

• Monoamine oxidaseBroader topic: MAO-A helps metabolize norepinephrine in neural and peripheral tissues.

• AdrenalineRelated: Noradrenaline is both adrenaline’s immediate biochemical precursor and a closely related signal.

• Alpha-1 adrenergic receptorRelated: It is the principal endogenous sympathetic agonist at many alpha-1 receptor sites.

• Chromaffin cellsRelated: Chromaffin cells release it alongside adrenaline, with proportions varying among cells.

• Locus coeruleusRelated: The locus coeruleus releases this chemical to influence neural activity across the brain.

• MDMARelated: Its increased signaling helps explain MDMA’s elevated heart rate, blood pressure, and wakefulness.

• Vesicular monoamine transporter 2Broader topic: VMAT2 stores norepinephrine in vesicles of sympathetic neurons and the brain.

• MethamphetamineBroader topic: Increased norepinephrine signaling contributes to methamphetamine’s arousal and cardiovascular effects.

• MirtazapineRelated: Mirtazapine increases noradrenergic signaling by reducing presynaptic inhibition of norepinephrine release.

• StimulantRelated: Increased norepinephrine signaling helps explain stimulants’ alerting effects.

• EphedrineRelated: Ephedrine promotes norepinephrine release from nerve endings, amplifying sympathetic signaling.

• ModafinilRelated: Modafinil's wake-promoting action may also involve norepinephrine signaling.

• NeuromodulationBroader topic: Norepinephrine adjusts neural responsiveness during alertness and changing task demands.

• TyramineRelated: Tyramine can trigger norepinephrine release from sympathetic nerve endings.

• AtomoxetineNarrower topic: Blocking its reuptake raises extracellular norepinephrine in relevant brain regions.

• ClomipramineRelated: Clomipramine’s active metabolite also inhibits norepinephrine reuptake.

• Julius AxelrodRelated: Axelrod traced how nerve cells take up and metabolize this messenger after release.

• TramadolRelated: Its reuptake inhibition is one part of tramadol’s non-opioid analgesic action.

• Neurogenic shockBroader topic: Its vasoconstricting effects make it a commonly used vasopressor when hypotension persists.

• PseudoephedrineRelated: Pseudoephedrine increases norepinephrine signaling, which narrows nasal blood vessels.

• ReserpineBroader topic: Its depletion reduces sympathetic signaling, contributing to reserpine's blood-pressure-lowering effect.

• AgomelatineRelated: Agomelatine can increase noradrenaline release through its 5-HT2C antagonist action.

• CathinoneRelated: Cathinone can increase noradrenergic signaling, contributing to wakefulness and elevated heart rate.

• XylometazolineRelated: This endogenous signaling molecule activates receptor pathways that xylometazoline imitates.
