Talk:Norepinephrine/Archive 1

SPAM
I am a grad student in biology at ASU -- just noticed that this page has been spammed. Look at the bottom, there are those pharmaceutical links and huge white space. CAN SOMEONE PLEASE FIX THIS?! I don't know how... I tried going to the history, but couldn't find the right version to revert! PLEASE HELP!?!?

Pronunciation
Hello, I'm curious as to the english pronunciation of noradrenaline and norepinephrine. Would someone please clue me in? 63.192.52.26 20:20, 1 September 2005 (UTC)

The pronunciation is "noor-ep-eh-nef-rin", listen to it here:

Norepinephrine or Noradrenaline?

If this substance is known as Noradrenaline outside the USA - in most of the world - shouldn't this article be called Noradrenaline instead of Norepinephrine? - Quirk 20:36, 9 Apr 2005 (UTC)


 * Hi, is there any chance we could rename this site to Noradrenalin(e)?!? Apart from people in the US, nobody uses the term Norephinephrine.


 * There is a huge problem with Norepi: Norepi will increase MAP drastically, so it eventually starts a baroreceptor depressor reflex (yes, the depressor center is back from holidays) which starts reflex bradycardia! Therefore it actually decreases the heartrate, lowers venous return after a bit, though you have a high MAP. Consequences are, that you probably let the patient go one step further in his shock level.


 * I too dislike the newfangled epinephrine and norepinephrine names, but I believe they were chosen as the main Wikipedia name because they are now the International Nonproprietary Name, as set by the WHO. See for arguments as to why they stink.

I have reverted this renaming of the article from Norepinephrine to Noradrenaline/Norepinephrine. There was no consensus in the above thread for this move, and to the have so WP:Boldly moved was therefore disruptive, especially given the active discussion at Talk:Epinephrine where again there is no consensus to move from the internationally agreed (by the World Health Organisation) International Nonproprietary Name. Finally see WP:MEDMOS "Naming conventions" for generally agreed naming of drugs. David Ruben Talk 00:19, 7 March 2007 (UTC)
 * Okay, so I broke something. I apparently tried to move the page a few minutes after you did, and now the Norepinephrine page has disappeared. I have to run out for now, so I can't take care of it at the moment. If someone can figure out what's going on or alert wikitech, I'd much appreciate it. Sorry for the trouble. --David Iberri (talk) 00:35, 7 March 2007 (UTC)
 * I think I've successfully restored Norepinephrine. Let me know if there are any other problems. --David Iberri (talk) 00:40, 7 March 2007 (UTC)

 * Must we keep with worn out british names??? —Preceding unsigned comment added by 129.176.151.10 (talk) 21:21, 3 June 2009 (UTC)

Noradrenalin is not a "worn-out British name"; like it or not it is the name used commonly throughout Europe and around the world. The fact that north America prefers norepinephrine does not justify cultural imperialism. By common usage the article would be entitled noradrenaline. It is also a more accurate reflection of history and etymology (see ). However, for political purposes the name norepinephrine has largely triumphed, and so this article is correctly titled.

I agree that this article should not put weight to norepinephrine over noradrenaline. In Australia one NEVER hears of epinephrine except if you read scientific articles from america. British and Australian articles would prefer to use adrenaline. Epinephrine is essentially an americanism and it is not an accepted alternative internationally. Also, I believe most americans would understand what is meant by adrenaline but I know that most Australians or British have no idea what epinephrine is. Adrenaline is hardly a 'worn out british name' but is the currently used term outside of the USA. — Preceding unsigned comment added by 203.52.130.149 (talk) 02:17, 27 February 2013 (UTC)

I also looked up the french term out of curiosity and they use adrenaline (with an acute accent on the 'e' of course). — Preceding unsigned comment added by 203.52.130.149 (talk) 02:25, 27 February 2013 (UTC)

The article argues that "medical authorities [4] have promoted norepinephrine as the favored nomenclature". However, the medical authorities being referred to are the U.S. National Library of Medicine - of course they are promoting it, they are (without critisism), obviously biased. The REST of the world uses "noradrenaline". Wikipedia (or Wikipaedia?) exist's through its foundations of allowing contributors to input from all corners of the planet, not just the USA, which pretty much makes the term 'norepinephrine' foreign to the vast majority of the English speaking world. Please re-title the article back to "noradrenaline" to suit the majority of this planet's English speakers. — Preceding unsigned comment added by 114.78.172.37 (talk • contribs) Looie496 (talk) 14:19, 17 June 2013 (UTC)

The image that shows the molecular structure of Norepinephrine has been removed by Anon.User 146.82.167.179 today. Does anyone know why ? Was there a problem with the figure ? -- PFHLai 22:03, 2004 Jun 28 (UTC)


 * I'm not aware of any problem with Image:Norepinephrine.png, except that the label for the alcohol group on the benzene was a little truncated. The chemistry was fine and the image definitely serves a purpose, so I've reverted. --Diberri | Talk 23:49, Jun 28, 2004 (UTC)

Metabolites
I'm going to have a go at elucidating the biological metabolites of noradrenaline (aka norepinephrine) in this article. Please expand upon this effort. Also, please mod my formatting so that it conforms. I'm afraid I don't have the patience to learn the required minutiae of preferred formatting :P - Adam


 * let me guess: You use Strattera yourself? :)

Naming Problem?
I found a small problem with the authors naming of some of the classes of drugs - both selective norepinephrine reuptake inhibitors and serotonin norepinephrine inhibitors have the acronym SNRI. Can anyone who has the knowledge please fix this in the post? And to the problem of which name it goes by, in all the scientific literature I've come across, its epinephrine - and I'm in Canada. Just take a look at your epi-pens - they're not adreni-pens. - Mike


 * EpiPen is a brand name; all that tells you is that the brand is american. Adrenaline vs epinephrine is a massive debate in medical literature, with entire books devoted to it. Epi-nephros is greek for "above kidney" Ad-renal is latin for the same thing. My favourite book title on the subject is "Even the greeks call it Adrenaline". :) The only reason for a difference is a now expired US patent which used the name "Adrenalin" for something entirely unrelated and someone decided it was too similar, so switched to the greek transliteration; which has since become the INN for some reason, even though the offending patent expired long ago and IMHO the name epinephrine should have expired with it. --KX36 (talk) 13:52, 2 October 2008 (UTC)

Vasopression isn't a word
Maybe this came about as a misunderstanding of the word "vasopressin," which is a hormone that causes vasoconstriciton.

I'm changing it heading to "Vasoconstriction." —The preceding unsigned comment was added by 146.203.126.65 (talk) 01:38, 18 March 2007 (UTC).

usage of in vitro
Under the heading Hypotension, there is mention of Norepinephrine's effects "in vitro" (which refers to within a test tube). It's likely that this was meant to read "in vivo". Thoughts? -Ryan —Preceding unsigned comment added by 204.140.142.46 (talk) 00:50, 28 February 2009 (UTC)
 * Actually, in vitro refers to observations under controlled conditions (ie, in an experiment), not necessarily "in a test tube." But the sentence you're talking about does seem to refer to findings observed in vivo, so I think you're right. --David Iberri (talk) 22:24, 28 February 2009 (UTC)

Neurotransmitter?
I have a hard time understanding this sentence:
 * Norepinephrine also has a neurotransmitter role when released diffusely in the brain as an antiinflammatory agent.

Does the body naturally release it in the brain to fight inflammation, or are we talking about the use of norepinephrine as an antiinflammatory drug? Norepinephrine only acts as a neurotransmitter when it is released as antiinflammatory agent? Why and how does this happen? Thanks, AxelBoldt (talk) 22:05, 19 August 2010 (UTC)


 * I agree that sentence is written in a very confusing way. I believe your first idea is most likely to be correct; the brain releases it to fight inflammation naturally. I rewrote the sentence in the article, based on the reference that was given to support the initial sentence. Please correct me if I have the wrong idea on this too. --Tea with toast (talk) 22:50, 19 August 2010 (UTC)

DEFUSES (not)
'diffuses' is intended if someone will kindly correct it.

Dispute: what does NE increase the tension of?
IP editor and I have been arguing about how NE increases blood pressure:  the IP editor wrote that it does so by increasing the tension of muscles; my understanding is that it results from contractions of the walls of blood vessels and that muscles don't come into the picture. The most recent edit had an edit summary saying tension of blood vessels refers to their length (like tension of a cable) whereas tension of muscles (of blood vessels) refers to their diameter -- which doesn't make sense to me. Would it be possible for anybody to find a good source that backs up one story or another? Looie496 (talk) 23:46, 14 September 2011 (UTC)

 * I've reworded the sentence a bit. But the whole paragraph is pretty technical, and I'm not sure that I've made it all that much more understandable. Looie496 (talk) 20:02, 15 February 2012 (UTC)


 * No, you did not. "[T]he [..] rate [...] in [...] probabilities" is just pure nonsense. '[A] "predictive cueing" situation' is an empty phrase. '[A]ttentional paradigms' is incorrect as no word 'attentional' exists. 'Yu et al.' may indicate someone living under a bridge as people have first names and some - professional titles. Wikipedia is for laymen and not for experts. Everything should be self-explanatory. The sentence was not too technical, but just badly written.--68.237.35.133 (talk) 21:35, 16 February 2012 (UTC)


 * No, it's actually just technical -- you'll find all of these terms commonly used in the academic literature on psychology. I don't fully agree with you that everything on Wikipedia should be self-explanatory -- my feeling is that the higher the level of a concept, the more background it is reasonable to expect from readers.  I do, however, agree with you that this particular article uses more jargon than it ought to.  Regards, Looie496 (talk) 23:59, 16 February 2012 (UTC)

The Need to Differentiate between Norepinephrine (Adrenaline) and Norepinephrine (Medical)
The function of norepinephrine (adrenaline) is continual use by our bodies in a multitude of ways. The medical use of a man-made form of it for a specific use is extremely recent. Therefore the natural function should be described--in detail--first. WP is written first of all for laypeople, not for doctors and medical students.

Drug box or "infobox neurotransmitter"?
Yesterday I replaced the "drugbox" template that has been on this page for a while with a neurotransmitter infobox; reverted, saying "restored drug box as it is a very important medication most commonly". I can't agree with that rationale. It is a moderately important medication but in my view it is far more important as a hormone and neurotransmitter, and the information in the neurotransmitter infobox is much more useful to the average reader. I'm starting to rework this article -- when I'm done I expect it will have one or two paragraphs about the role of NE as an injected drug, and several dozen paragraphs about its role as a hormone and neurotransmitter. What do other editors think? (Consider this a sort of informal RfC.) Looie496 (talk) 13:30, 24 September 2015 (UTC)


 * It is both a drug and neurotransmitter. What is the best way to have both sets of information with minimal overlap in scope? Can both infoboxes be used? What are the drawbacks of using two infoboxes?  Blue Rasberry   (talk)  13:53, 24 September 2015 (UTC)
 * The main drawback is that both infoboxes are pretty large. It would be possible to place a trimmed-down version, as I've placed here, in the section on medical uses, but it is still a bit awkward.  I'm not sure that all of those identifiers are necessary -- most of them I don't even recognize. Looie496 (talk) 15:12, 24 September 2015 (UTC)


 * while you do have a point, I would have to go with DocJames restored drug box as it is a very important medication per --Ozzie10aaaa (talk) 13:56, 24 September 2015 (UTC)

Everyone has the hormone, only some will receive it as a drug. Matthew Ferguson (talk) 14:46, 24 September 2015 (UTC)


 * I came here from the note at WT:NEURO. I'm a bit amused at how this seems like a disagreement between editors with MDs and editors with PhDs, but to me, this is very clearly a case where the role as a neurotransmitter should take priority. Its status as a drug results from the fact that it is a neurotransmitter, not the other way around. Dopamine is chemically similar, and it's used medicinally, but our page uses the transmitter infobox at the top. Pharmacologically, NE is just one of many sympathomimetic drugs in clinical use, but it really does have a unique historical place in the history of the science of neurotransmission. I have no objection to giving prominent coverage to its drug use as well, and perhaps there is some way to present the drug data in graphical form somewhere on the page, but the box at the top should treat it first as a neurotransmitter. --Tryptofish (talk) 16:04, 24 September 2015 (UTC)
 * For the sake of transparency -- I switched the dopamine article from "drugbox" to "infobox neurotransmitter" a few days ago, so that probably shouldn't be used as a precedent. Looie496 (talk) 16:39, 24 September 2015 (UTC)
 * LOL! Duly noted. I suggest the creation of a PhD-bot, to do that at numerous pages. --Tryptofish (talk) 16:49, 24 September 2015 (UTC)


 * This is one of the most important medications of my profession. People care a great deal about drugs / medications. Keeping WP more clinically focused is important rather than having it focused around mechanisms of action. Doc James  (talk · contribs · email) 16:47, 24 September 2015 (UTC)
 * Well, it's one of the most important transmitters of my profession! I think it's important for Wikipedia to be educational. In no way am I saying that we should make it difficult for readers to find the clinical stuff. But how about this: can we develop a modified infobox that combines the two? --Tryptofish (talk) 16:55, 24 September 2015 (UTC)

If we look at the "drugbox" it contains most of the info as the "neurotransmitter box" bot also contains important clinical informoration that the neurotransmitter box does not. Doc James (talk · contribs · email) 16:52, 24 September 2015 (UTC)
 * What about creating a Norepinephine (drug) article to discuss this aspect, much like we have separated Cannabis and Cannabis (drug). Sizeofint (talk) 16:56, 24 September 2015 (UTC)
 * I will also point out that this is currently a high-importance neurology and molecular biology article but only a mid-importance pharmacology article. Might this indicate that the neurotransmitter aspect should have precedence? Sizeofint (talk) 17:08, 24 September 2015 (UTC)


 * could we merge in the clinical medication content into the neurotransmitter box for when both apply? I do not find how important different projects rank something to be a very strong argument. Doc James  (talk · contribs · email) 17:15, 24 September 2015 (UTC)
 * I'm the wrong editor to give advice on technical stuff, but assuming that one of the infoboxes can be edited to add more information types, then that seems like the best way to go. In other words, maybe we could come up with a merged or combined box that includes both the basic science and the clinical information. --Tryptofish (talk) 17:32, 24 September 2015 (UTC)
 * I can do that. I created the "infobox neurotransmitter" template and can modify it.  Alternatively it would be possible to create a special template just for this article ("infobox norepinephrine") if we want to go that way. The main issue is to keep it from getting outrageously long, but in my opinion some of the chemistry info in the drugbox has no value to anybody and could be left out. Looie496 (talk) 17:59, 24 September 2015 (UTC)
 * I think it is possible to embed one infobox inside another using "|module =" parameter. They do it at Infobox lighthouse. Sizeofint (talk) 17:56, 24 September 2015 (UTC)
 * I agree with that approach. --Tryptofish (talk) 18:13, 24 September 2015 (UTC)

I am mainly wanting the stuff under "clinical data". As a number of neurotransmitters are meds would be good to have this in the formal box. Would be good to adjust the dopamine box aswell. Doc James (talk · contribs · email) 19:10, 24 September 2015 (UTC)
 * Embedding has the advantage of being simpler to implement and maintain. We wouldn't have to worry about propagating a change in Drugbox to Infobox neurotransmitter. Essentially it allows for separation of concerns. They way they do it with lighthouses and historic places looks good I think. See for example Middle Bay Light. Sizeofint (talk) 22:09, 24 September 2015 (UTC)


 * As far as I can tell the Drugbox template doesn't have good support for embedding, but is this satisfactory? Looie496 (talk) 13:33, 25 September 2015 (UTC)
 * You'd have to look at Template:Infobox NRHP to see how they allow for embedding. I haven't figured out infobox programming yet. Sizeofint (talk) 17:15, 25 September 2015 (UTC)

Split
As already suggested above, I think this article should be split into two (similar to insulin and insulin (medication)). I do not see why the drug is automatically more important that an neurotransmitter. In addition to the problem of the infoboxes, the suggested order of sections recommended by WP:MCBMOS and WP:MEDMOS conflict. Most of the prose in this article is about the neurotransmitter and not the drug. Putting the drug section first puts indue weight on the drug. We could solve all these inconsistencies by splitting the article into Norepinephrine and Norepinephrine (medication). Boghog (talk) 15:56, 25 September 2015 (UTC)
 * How about a disambig. Than Norepinephrine (neurotransmitter) and Norepinephrine (medication). I think that would give equal weight to both topics and would be a good way forwards for these types of issues. Each type of article can than get the proper infobox.

 * If you're referring to an Argument to moderation, the answer is no. It's a logical fallacy. Sizeofint (talk) 20:36, 25 September 2015 (UTC)
 * The neurotransmitter is unequivocally the primary topic. There is absolutely no reason to DAB the norepinephrine page just for the sake of a medication that the vast majority of readers probably wouldn't care to read about anyway.  How many incoming backlinks to this page do you think are related to the drug as opposed to the neurotransmitter?  Seppi  333  (Insert 2¢) 19:16, 25 September 2015 (UTC)
 * Edit: Neurotransmitter as a parenthetical DAB isn't even a sufficient scope anyway, since it's also a hormone.  Seppi  333  (Insert 2¢) 19:19, 25 September 2015 (UTC)
 * IMO that norepinephrine is a medication is the main topic. I however see a compromise as reasonable in this situation as others disagree. We know that 5% of google searches are for health care information (diseases and medications). People care a great deal about this content.
 * What we could do is create a disambig with one for the medicine and one for the neurotransmitter/hormone and see were most people go. If they are within a factor of 5 or 10 of each other than we keep the disambig. If one is more than 10 fold the other than it becomes the primary article. Doc James  (talk · contribs · email) 19:24, 25 September 2015 (UTC)
 * It's hard to quantify this, but I note that dobutamine, a drug more or less comparable to norepinephrine in clinical usage as I understand it, shows about 10000 page views over the past 30 days, whereas the norepinephrine article shows over 40000. That suggests to me that 3/4 of the views relate to other aspects. Looie496 (talk) 19:35, 25 September 2015 (UTC)
 * Dobutamine is way way less used than norepinephrine clinically. While I frequently ( a couple of times a week use norepi) I have never used dobutamine. Doc James  (talk · contribs · email) 19:46, 25 September 2015 (UTC)
 * Why not treat the norepinephrine page in the same way as epinephrine is treated - with the drug mentioned in the lead and just incorporated into the article? --Iztwoz (talk) 20:52, 25 September 2015 (UTC)
 * I am OK with a disambig. Merging of two lengthy infoboxes is messy and produces an excessively long infobox that doesn't function well for what is currently the main subject of this article, the norepinephrine neurotransmitter,  Currently there are only two short paragraphs ("Medical uses" and "Drug interactions") that deal specifically with the norepinephrine medication. Adding additional medication specific sections (WP:PHARMOS) on "Contraindications", "Adverse effects", "Overdose", and especially "Pharmacology" (that overlaps with "Function") would clash with the present organization of this article.
