	Noradrenaline Reuptake Inhibitors (Site not responding. Last check: 2007-10-26)
		However, the recent development of reboxetine, the first selective noradrenaline reuptake inhibitor, has allowed clinical investigation of the role of the noradrenergic system in different aspects of depressive disorders.
		In clinical trials, the use of reboxetine has shown that selective noradrenaline reuptake inhibition is an effective approach to alleviating depression.
		Selective noradrenaline reuptake inhibition, as exemplified by reboxetine, therefore offers a significant improvement in antidepressant pharmacotherapy, and an opportunity to increase our understanding of the role of noradrenaline in depression.

	Norepinephrine - Wikipedia, the free encyclopedia
		Norepinephrine, known as noradrenaline outside the USA, is a catecholamine and a phenethylamine with chemical formula C
		It is released from the adrenal glands as a hormone into the blood, but it is also a neurotransmitter in the nervous system where it is released from noradrenergic neurons during synaptic transmission.
		In mammals noradrenaline is rapidly degraded to various metabolites.

	Noradrenergic transmission
		Once synthesized, noradrenaline is actively taken up into synaptic vesicles, using hydrogen ion gradients to drive uptake (The transport protein is similar to those that mediate reuptake from the synaptic cleft, but those transporters use sodium ion gradients).
		ATP is complexed with noradrenaline in the synaptic vesicle, and acts as a co-transmitter.
		Noradrenaline release is profoundly influenced by homotropic and heterotropic regulation.

	British Journal of Pharmacology - Comparison of changes in the extracellular concentration of noradrenaline in rat ...
		In contrast, the rapid increase in extracellular noradrenaline concentration induced by d-amphetamine is consistent with this being mainly due to an increase in Ca -independent release of noradrenaline.
		These active metabolites are potent uptake inhibitors of both noradrenaline and 5-HT in vitro (Cheetham et al., 1993; 1996) and in vivo (Luscombe et al., 1989) and predominantly mediate the pharmacological effects of sibutramine in vivo (Luscombe et al., 1989).
		Noradrenaline efflux is affected in different ways by different anaesthetic agents and chloralose appears to decrease the concentration of extracellular noradrenaline in the hypothalamus, at least (Shimokawa et al., 1998).

	Noradrenaline (Site not responding. Last check: 2007-10-26)
		Noradrenaline (norepinephrine) is used to support blood pressure in foals with failing circulation.
		Noradrenaline has to be used very carefully, as too much tone in the blood vessel walls can cause them to constrict, and actually prevent forward flow of the blood.
		Noradrenaline is usually used in combination with dobutamine.

	Critical Care \| Full text \| Noradrenaline and the kidney: friends or foes?
		Noradrenaline is very effective in raising arterial blood pressure and, under almost all circumstances, can be titrated to achieve the desired MAP in a given patient.
		In fact, noradrenaline infusions have been reported to decrease splanchnic [6,7] and renal blood flow [8,9,10] under normal circulatory conditions, as well as during essential hypertension and hypovolemic hypotension.
		This controlled study strongly suggests that noradrenaline is superior to high-dose dopamine in restoring blood pressure in septic vasodilated patients, and that such correction of blood pressure induces an improvement in urine output.

		Noradrenaline (norepinephrine) tartrate is a substance released naturally by the nerve cells.
		Noradrenaline normally produces effects such as increased heart rate, increased blood pressure, dilation of pupils, dilation of air passages in the lungs and narrowing of blood vessels in non-essential organs.
		Noradrenaline is used to restore blood pressure to normal in emergency situations when blood pressure has dropped dangerously low.

		A detailed review of the role of CNS noradrenaline in pain can be found in html or pdf.
		Noradrenaline (NA) is a key neurotransmitter of the endogenous pain inhibitory system.
		A major caveat to this noradrenergic hypothesis of pain is that most experimental studies on which it is based use acute rather than chronic pain models and therefore do not mimic the major types of pain encountered in humans.

	Mechanisms of Ca2+ sensitization of force production by noradrenaline in rat mesenteric small arteries -- Buus et al. ...
		The effects of noradrenaline were investigated at constant membrane potential by comparing fully depolarized intact arteries in the absence and presence of noradrenaline.
		Any effects of noradrenaline were thus not due to depolarization, and the ability of noradrenaline to increase Ca sensitivity under these conditions is demonstrated in Fig.
		The inhibiting effect on the noradrenaline response thus cannot be explained by any enhancing effect by calphostin C itself precluding any further enhancement by noradrenaline, but appears rather due to a specific inhibition of the increase in phosphorylation caused by noradrenaline.

		The central functions of noradrenaline are regulation of alertness and the wakefulness-sleep cycle, maintenance of attention, memory and learning, cerebral placidity and neuroprotection.

		By the drug-induced decreases in levels of noradrenaline or serotonin between 1 and 2 weeks after birth, the number of synaptic profiles was decreased by 29-55% compared with that of control animals.
		Later in the developmental period, the function of noradrenaline and serotonin in facilitating synapse formation and maintenance became less prominent than that in younger animals.
		We suggest that both serotonin and noradrenaline are necessary for synapse formation during the early stages of development of the rat visual cortex.

		One implication of increased noradrenaline clearance is that plasma noradrenaline levels in space underestimate increases in sympathetic nervous activity.

	Dec 2000: Green Tea and Thermogenesis (pg 2)
		Noradrenaline is synthesized in the sympathetic nerves and stored in storage vesicles.
		Uptake 2: Some of the noradrenaline diffuses away from the receptors and is transported by extra-neuronal cells (uptake 2) and metabolized by catechol-O-methyl-transferase (COMT).
		For this reason, Dulloo concluded that the thermogenic effect of green tea is "likely to be highly dependent upon the release of endogenous NA [noradrenaline]." Clearly, green tea (by itself) is going to be a "your mileage may vary" situation.

	CHEST: Inhibition of nitric oxide synthesis improves the vasoconstrictive effect of noradrenaline in sepsis (Site not responding. Last check: 2007-10-26)
		In nonseptic sheep, noradrenaline induced a significant increase in systemic vascular resistance (from 2,973 [+ or -] 637 to 4,561 [+ or -] 1,287 dyn/s/[cm.sup.-5]/[m.sup.-2]), whereas the increase caused in those that received LNNA was nonsignificant (5,562 [+ or -] 3,489 to 6,693 [+ or -] 2,871 dyn, s, [cm.sup.-5], [m.sup.-2]).
		It is concluded that increased synthesis of nitric oxide contributes to the depressed vascular reactivity to vasoconstrictor agents characteristic of sepsis.
		Sheep weighing between 41 and 55 kg were anesthetized with pentobarbital (30 mg/kg IV bolus followed by 4 mg/min), intubated, and connected to a volume-cycled respirator with a respiratory rate of 10 per minute and a tidal volume of 15 ml/kg.

		First, it is apparent that the system involved is dependent on noradrenaline and to a much smaller extent on serotonin: the greater impact of noradrenergic as opposed to serotoninergic drugs, and the greater effect of phenylalanine as opposed to tryptophan, indicate this.
