Question 1

what is the definition or description of: norepinephrine allergy?

Accepted Answer

A drug allergy?: Norepinephrine is a hormone related to epinephrine (adrenalin). It is a normal constituent of the body, and a true allergy is unlikely. More likely you are describing a reaction to supplemental norepinephrine as a drug. It is primarily used to raise blood pressure in patients with shock. What type of reaction are you asking about?

Question 2

why norepinephrines cause sexual side effects?

Accepted Answer

Norepinephrine: Norepinephrine and some other neurotransmitter can have side effects because of their inherent pharmocokinetics...Or how they work.  If you have side effect, discuss other options with your physician.

Question 3

what causes acceleration in reuptake or norepinephrine and dopamine?

Accepted Answer

Unknown.: Your question is extraordinarily sophisticated. It reflects the theory that since antidepressant medications inhibit reuptake, then reuptake may have been "accelerated." But too little is known to be sure about about this.  Reuptake, for example, may have been normal, with a need for additional inhibition. At this point molecular theories of depression lag behind clinical knowledge.

Question 4

would norepinephrine cause an amphetamine positive?

Accepted Answer

On a tox screen?: I'm not sure i understand your question. If you mean, "would norepinephrine cause a tox screen to show positive for amphetamine?", the answer is "no". Norepi. Is a naturally occuring neurotransmitter without which you would not be alive. Amphetamine would be present in the bloodstream only if you are taking that drug.

Question 5

smoking causes epinephrine release in the body, does it cause a release of norepinephrine too?

Accepted Answer

Smoking: Yes it can also cause the release of norepheneprine.

Question 6

does acetylcholine cause dopamine, norepinephrine, or epinephrine to be released?

Accepted Answer

Yes, since: Acetylcholine is the preganglionic transmitter

Question 7

why does norepinephrine cause more vasoconstriction than heart rate increase?

Accepted Answer

Alpha receptors : The arteries like norepinephrine more and constrict tighter than with epi.

Question 8

what could cause/explain significantly elevated (4.5x the norm range)plasma norepinephrine in blood test, but normal urinary norepinephrine levels?

Accepted Answer

Normal variation: Plasma levels vary with rate of production and rate of excretion.  Hormone levels vary a great deal in production by stress and by time of day and by medication effects.  Rate of excretion depends on liver metabolism and clearance by the kidney.  Kidney clearance may be normal but will eventually clear the hormone over time.  High serum level means high production by some uncertain cause.

Question 9

what could cause/explain significantly (4.5x norm rang)elevated plasma norepinephrine levels in blood test , but normal urinary norepinephrine levels?

Accepted Answer

Several things: Including daily doses of snri's  --         medications used to treat depression. See your doctor; the evaluation can be complex.

Question 10

24 hour urine dopamine level is very high. the range is up to 500. my level was almost 700. what can cause this. all else normal (epinephrine, norepinephrine, metenephrine , etc) although plasma epinephrine was elevated 2 x range ? urine normal?

Accepted Answer

: I assume you had these tests because of high blood pressure. I assume you're not taking any meds that can raise urinary dopamine. A study showed that elevated urinary dopamine alone wasn't diagnostic of pheochromocytoma. Elevated plasma epinephrine alone is nonspecific &amp; seen in stress, vigorous exercise, alcohol use,smoking, caffeine excess. An endocrinologist can advise you best.
