Neurotransmitter: Norepinephrine (ne) is a sympathomimetic catecholamine that is synthesized in the adrenal medulla, in sympathetic neuron terminals, and in nuclei in the brainstem and pons. One of the largest of these is in the locus coeruleus. Along with serotonin and dopamine, norepinephrine serves as a neurotransmitter in the brain. Antidepressants effect these in various ways, providing different results. ...Read more
Neurotransmitter: Norepinephrine (ne) is a molecule used to carry signals to organs in the body. Ne is present throughout the body including the heart, blood vesssels and brain. Ne work with certain adrenergic receptors. Outside of the brain, ne primarily cause blood pressure to increase. Ne can be given intravenously to support blood pressure. In the brain, it is thought to effect attention and emotion. ...Read moreSee 1 more doctor answer

See below: Levophed’s dosing is variable, depends on the condition treated, and may itself change depending the reference or guideline you consult). A common treatment is for low blood pressure/shock, 0.1-0.5 mcg/kg/minute, adjusted to desired pressure response. An older approach some still use is flat dosing (without regard to patient weight) of 8-12mcg/minute to start and a maintenance dose of 2-4mcg/min. ...Read more
Noradrenalin: Comes from dopamine which is another neurotransmiter and it is a hormone that helps us stay alive during stress. It has many important other function from the memory to the heart rate and wellbeing sensation. Regulators" such as angiotensine II and epinephine increase it. Also cocaine, amphetamines (speed), and antidepressants increase the reuptake. Can be an adrenal tumor (pheochromocitoma) ...Read more
Catecholamines: Behavior is much more complex than neurotransmitter levels alone. But norepinephrine (ne) acts mainly in an area of your brainstem called the locus coeruleus. When released, ne triggers the stress response. Ne is also involved in pain, cognition, mood, emotions, movement and blood pressure. Dopamine is involved in regulating mood, pleasure, delusions, psychosis and drug abuse -- and more. ...Read more
They don't: Antidepressants don't actually contain norepinephrine (ne), but several can affect ne reuptake into the neuronal synapse. The result is more ne available in the synapse, one theory of antidepressants' effectiveness. Antidepressants with this kind of activity include tricyclics, effexor, pristiq, cymbalta, savella, (milnacipran) and fetzima. They also affect serotonin reuptake. Wellbutrin affects ne ; da. ...Read moreSee 1 more doctor answer

Extremely rare one: Some people who suffer from depression are helped with drugs that increase the norepinephrine stores in nerve endings. Drugs such as Effexor (venlafaxine) or wellbutrin do this.
