Need doctor's help! what do plasma dopamine and norepinephrine levels indicate?

Need doctor's help! what do plasma dopamine and norepinephrine levels indicate?

It depends: Dopamine and norepinephrine are endogenous hormones/neurotransmitters released in the body. If plasma levels are elevated, this may indicate a neuroendocrine abnormality, such as pheochromocytoma. ...Read more

Please explain what levels of neurotransmitters a tourette patient has to have, serotonin, dopamine, adrenalin & norepinephrine, thank you?

Please explain what levels of neurotransmitters a tourette patient has to have, serotonin, dopamine, adrenalin & norepinephrine, thank you?

Go after it!: Kenneth, that's a great question. I encourage you to get a Ph.D. in neurobiology and devote your career to finding out the answer, because if you do, you will win about three Nobel Prizes in Medicine. In fact, you'll win if you can find an effective way to measure?neurotransmitters in the living brain all at once for more than a minute at a stretch AT ALL, let alone for Tourette's. ...Read more

Sine seratonin depletes other nerotransmitters like dopamine, norepinephrine, and epinephrine...By "deplete" does it mean a permanent thing?

Sine seratonin depletes other nerotransmitters like dopamine, norepinephrine, and epinephrine...By "deplete" does it mean a permanent thing?

Not correct: Serotonin does not deplete other neurotransmitters, but there is a balance especially between Dopamine and serotonin. This balance is dynamic and constantly re-establishing itself. Unless there is damage to neurons (which there can be when abusing certain drugs) neurotransmitter changes would not be permanent. ...Read more

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

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 the differences between levophed, (norepinephrine) dopamine and dobutamine?

What are the differences between levophed, (norepinephrine) dopamine and dobutamine?

Receptors: These three medications are used to support the heart and cardiovascular system ie. blood pressure and heart rate. They are known as sympathomimetics and have a similar response to what you would think of as adrenaline. Each has variable effect on either heart rate, heart function (in terms of strength of 'squeeze') and on blood vessels which would translate to higher blood pressure. ...Read more

Can you explain the differences between levophed, (norepinephrine) dopamine, and dobutamine?

Alters physiology: These are very simple answers to a complex question. Levophed (norepinephrine) increases blood pressure; Dopamine increases heart rate, blood pressure and cardiac function (contractility); Dobutamine increases cardiac contractility and heart rate. ...Read more

I was wondering what are the differences of levophed, (norepinephrine) dopamine and dobutamine in terms of their action?

You Asked for It----: Dobutamine- direct b1 receptor stimulant or agonist in the sympathetic nervous system. Levophed- vasoconstrictor peripherally (alpha adrenergic effects) and beta adrenergic stimulant at the level of the heart and coronary vessels dopamine- dual b1 and Alpha adrenergic effects. Useful in hypovolemic shock because of conservancy of renal blood flow. Also, works centrally in other complex ways. ...Read more
