What is norepinephrine?

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...

What is norepinephrine? Another type of adrenaline?

Yes. Norepinephrine is epinephrine(adrenalin) minus one small chemical "side group". They are very similar, but do to the molecular difference, even though they do many of the same things, there are subtle differences in function, especially in regards to neurotransmission. Read more...

What p450 enzymes are inhibited/induced by seroquel, (quetiapine) and what does a dopamine/norepinephrine antagonist do? Reduce dopamine levels? Specifics please?

Neither. Seroquel (quetiapine) passes through the cyp450 3a4 pathway & is extensively metabolized, but it neither inhibits nor induces the pathway itself. On the other hand, it's metabolism may be significantly affected by other medications. For instance, Dilantin induces the pathway causing seroquel (quetiapine) to be rushed through the pathway, leading to less-effective, lower blood levels. Antagonists are blockers. Read more...

What are some causes of excessive norepinephrine? What tests are used to determine this?

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...

What are the effects of norepinephrine and dopamine?

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...
