What Is The Difference Between Norepinephrine And Epinephrine
1 extra carbon atom: Epinephrine has 1 more carbon & 2 more hydrogen atoms then norepinephrine. This small difference makes the molecules look different, so they interact differently with receptors, and have different effects. One example: norEpinephrine narrows blood vessels, increasing blood pressure; Epinephrine can narrow some arteries while dilating others, and can raise or lower blood pressure. ...Read moreSee 1 more doctor answer
Both: Are made in the adrenal glands of the body and are released in response to a need for increased energy. The fight or flight phenomenon. The biggest difference is that nor-epi causes more vasoconstriction of blood vessels where epi causes more increase in heart rate and cardiac output through contractility. ...Read moreSee 1 more doctor answer
Synthesis & Locale: Norepinephrine (ne) and Epinephrine (e) are both sympathomimetic catecholamines that are synthesized in the adrenal medulla and terminals of sympathetic neurons. Along the metabolic pathway, ne is synthesized first -- and when an enzyme adds a methyl group, you have epinephrine. Ne is the main catecholamine in peripheral tissue and sympathetic neurons. E is mostly made in the adrenal medulla. ...Read more
May be thyroid: If you are not takin stimulants like caffeine or energy drinks and have a yearly physical with normal blood work then be thankful. It could be hyper active thyroid but you would also have weight loss with anxiety and difficulty sleep along with other symptom. If not seeing a physician for more than a year it may be time ...Read more
Assuming: This results are serum levels. Norepinephrine level in pg/ml of 946 are high for an adult patient. Epi level appear normal. Serum levels without any more info like 24 hrs urine collection and ct results plus symptoms do not mean a lot. Patient should calm and supine for 30 minutes before collection. Assuming they are working out you for pheocromocytoma. Talk to your doctor with results. ...Read moreSee 1 more doctor answer

My 11 year old son has highly elevated levels of norepinephrine and epinephrine. How can we help him?
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
14/male results/ catecholamine norm?
Norepinephrine, supine 136.0 pg/ml
* epinephrine, <10 pg/ml
*dopamine, <10 pg/ml
norepinephrine, stand 457.0 pg/ml
epinephrine, 14.0 pg/ml
dopamine, 16.0 pg/m
Blood work showed supine norepinephrine 183pg/ml, epinephrine 11, dopac 1204, dopa 2339; standing norep 639, epi 121, dopac 1099, dopa 1992, normal?
I read that a certain amount of cortisol has to be in the adrenal cortex for norepinephrine to be converted to epinephrine. Can anything substitute?
Catecholamines: E and NE are made in the adrenal medulla. In Addison's, where there is no cortisol circulating, there is higher NE and lower E, presumably due to cortisol effects on the adrenal medulla production of catecholamines. If you have adrenal insufficiency and are taking your hydrocortisone, this should not be an issue. ...Read more
Does low blood pressure cause norepinephrine and epinephrine to be created to raise blood pressure, or am I way off?
How come people use epinephrine for heart attacks, and not norepinephrine? And would one or both be useful for a first aid kit?
What are norepinephrine and epinephrine's effects on heart rate, blood pressure, vasoconstriction, sensitivity to pain, and heat production.
EPI: It increases heart rate and blood pressure (sometimes dangerously). It causes vasoconstriction. Variable effect on pain but generally increases sensitivity and because it ramps up your metabolism it increases heat production. Follow your docs instructions very carefully and don't freelance. ...Read more
