In the "Pharmacology" section it is stated "Its mechanism of action in this indication is not fully understood, but as an opioid-receptor antagonist it's likely to be due[citation needed] to the modulation of the dopaminergic mesolimbic pathway which is hypothesised to be a major center of the reward associated with addiction (being one of the primary centers for risk-reward analysis in the brain, and a tertiary "pleasure center") that all major drugs of abuse are believed to activate." There is a citation needed and I'd like to provide it with additional details. This is the reference: "Neurochemical and functional correlates of naltrexone-induced opiate receptor up-regulation" http://www.ncbi.nlm.nih.gov/pubmed/2982011 Let me discuss reasoning for moment and then the proposed change: Mu agonism is known to lead to dopaminergic(reward) action. Anhedonia from mu opioid abuse is strongly correlated with downregulation of mu and dopamine receptors. Most addiction is strongly correlated with downregulation of dopamine in the NAcc and therefore less dopaminergic action and subsequently less reward. Antagonism is known to generally result in the up-regulation of the antagonised receptor. Up-regulation generally leads to increased activation via endogenous ligands Therefore it is likely that the positive effect of naltrexone is mediated through increased endogenous reward. And while alcoholism is not directly correlated with mu agonism, there is anecdotal evidence that alcohol is used to alleviate pain, physical and emotional (similarly experienced in the brain) so the additional endogenous pain relief may also be involved. I'm sure this could be added more concisely in the article and if someone else would like to do so when they add the reference I'd appreciate it. Nemesis75 ( talk) 04:13, 5 March 2011 (UTC)
The statement, "However given that it is a long-acting antagonist, Naloxone would be a more ideal antidote in emergency situations," is incorrect (or atleast worded strangely). Naltrexone has a half life of 10 hours, while naloxone has a half-life of 1-2 hours. Both are effective at rapid opioid detox (onset 1-3 minutes), but "It is very important that the relatively short duration of action of naloxone be borne in mind, because a severely depressed patient may recover after a single dose of naloxone and appear normal, only to relapse into coma after 1-2 hours." from Basic and Clinical Pharmacology, 10th Ed., Katzung, pp 506-507. (1/2 life data and onset data also from this reference).

Naltrexone can also be admisistered as a low dose implant. These implants can remain effective for up to 12 months. They dissolve slowly and are usually put in under a local anaesthetic in the left iliac fossa. Although not licensed, they are available in the UK at specialist clinics, in the USA and in Australia. Jenny Sudell (Isle of Wight)
I have a major complaint about this article: it's so full of scientific jargon that it's quite hard for the layman to read. I don't know anything about Naltrexone except that it's some kind of implant used to treat heroin addiction, and came here hoping to learn more, as most people do when they come to wikipedia. But I gave up after a couple of paragraphs because this is a page designed for people who already know what they're talking about, not for people like me who have degrees in literature and can't tell an "iliac fossa" from a hole in the ground. ;) Thing is, I think that this page draws more attention from people out of the know than people in the know. I don't suppose one of you fine people might want to throw in a paragraph at the top or bottom that gives a simpler, jargon-free explanation of what Naltrexone is, and how it works? Surely "iliac fossa" could, for one paragraph, be replaced by "plate of the hip bone," and "opioids" replaced by "opiates and similar drugs," or "drugs in the family of heroin, opium, and morphine"? Stuff like that. Just a thought. My rain face 01:08, 23 April 2006 (UTC)

My doctor has prescripted naltrexone to prevent self harm behaviors. I found a couple of journal articles related to this, but I didn't find any mention to this in the wikipedia article. Could more information on this be included?
The rapid detoxification subsection does not cite any sources and I believe many of the aspects are incorrect as they appear to be referring to ultrarapid detoxification. Additionally there appears to be references in this section to naltrexone maintenance therapy for opioid dependence which is a completely different treatment modality than detoxification as it is continued indefinitely whereas detoxification is a finite process. One could certainly undergo rapid detoxification using naltrexone and transition to maintenance naltrexone dosing to maintain opioid abstinence but this is utilizing two different treatment types. -- Thiswouldbemark ( talk) 20:20, 16 April 2008 (UTC)

I was doing a "drive-by" edit when I noticed that Crohn's is mentioned twice within the same section - once under the Low-Dose Naltrexone heading and one under its own heading.

Why is putting in more than one reference about low-dose naltrexone excessive? Following this "logic", then one source on any subject would be enough... why read any other other authors? why reference anybody else who is using the same drug, for different purposes....? is it all excessive? since when is science advanced by only following one person's writings(s).... If the previous redactor would only realize that he has now cut the references on low-dose naltrexone to one site and ONE INDIVIDUAL, perhaps he might be a bit more open minded.... Naltrexone seems to help patients with multiple diseases... why not let those references be stated by those who post their own results...?
Marcelo Hoffmann, writing from northern California, on July 2nd, 2005
Dear Jfdwolff. I did include what you loosely call "repeats" (two double references from the same site...), but could you just try checking the other sites that I previously referenced, and prove to me and others that they were from the same LDN source (individual/site ), as you claimed... particularly given that one is referenced to a U.K. site and one based in Boston, and completelely and provably separate from the LDN site in New York, N.Y.......: just try clicking on "Multiple Sclerosis Research Center" (UK; http://www.msrc.co.uk/index.cfm?fuseaction=show&pageid=777); and also on "Interview with LDN researcher Dr. Agrawal" ( http://www.bostoncure.org:8080/article.pl?sid=05/01/27/1748256) Are these repeats too.... ? Is writing/describing/referencing the same/related topic from a different site/author a repeat....???
I certainly do not claim such expertise to be able to choose the one and ONLY universal reference that you claim.... and in case you cared.... information about low-dose-naltrexone for multiple medical indications and from multiple original sources could be life-saving for those patients or interested parties who would read it for treatment possibilities for their disease.... but only, and just in case you cared....! Marcelo Hoffmann
What a dialogue....! instead of responding to my explicit logic and thinking, issue a perentory command to stop a reference-stating behavior that is at worst somewhat redundant, and at best contributory (at least for some people, some of the time...). But this time, claiming absolute knowledge of what is best, for him/others, and Wikipedia..... I guess according to JFW, hyper-references should not be added to Wikipedia... after all, the statement "Wikipedia needs original content, not links..." is rather broad and would appear to leave no option(s).... hardly worth bringing the topic of multiple references to the discussion section of naltrexone.... for this sort of "dialogue" (or lack thereof....) Marcelo Hoffmann July 6, 2005
The second sentence states, "This is true even in those who continue drinking while taking naltrexone, but then it is less effective in helping people to stop completely.", however, the findings in the journal reference used are actually contrary to this statement. The findings were that naltrexone was MORE beneficial if prescribed to moderate or heavy drinkers vs. placebo compared to prescription to patients for which abstinence had already been achieved vs. placebo. In my opinion this statement should be removed. —Preceding JameOxford ( talk) 21:46, 19 October 2015 (UTC)
"The first is to reduce craving while naltrexone is being taken. The second, referred to as the Sinclair Method, occurs when naltrexone is taken in conjunction with normal drinking, and this reduces craving over time. The first effect only persists while the naltrexone is being taken, but the second persists as long as the alcoholic does not drink without first taking naltrexone."
Am I alone in not being able to puzzle that out? I keep reading that as "naltrexone reduces craving" and "naltrexone reduces craving" - what am I missing? —Preceding unsigned comment added by 209.6.39.11 ( talk) 05:27, 9 December 2009 (UTC)

Surely one of the criticisms should be its cost. Vivatrol, according to a Nov 4, 2015 Marketplace.org show, is $1200 (in the USA) per dose. As a side note, I find it hard to beleive that the several (US) FDA reviews have all relied on a single (unethical) Russian study. (Unethical in the sense that ethics dictate the "best available therapy" be used as the control, any other study design couldn't be approved in the USA and many other countries.) 216.96.77.183 ( talk) 00:02, 5 November 2015 (UTC)

The article says: "The Sinclair method is a method of using opiate antagonist such as naltrexone to treat alcoholism by having the person take the medication about an hour before they drink alcohol, and only then". (Emphasis mine.) I'm no doctor, and I'm no expert, but "only then" seems to me like it might be too conservative. It may cost the patient some extra money, but in practice, I still think it could be a good safeguard during early sobriety for the patient to take naltrexone every morning, in case they forget to take it before their usual evening drinking session begins. No? Thanks in advance, TealHill ( talk) 18:20, 29 September 2016 (UTC)
Dear all. The article says: "The Sinclair method is a method of using opiate antagonist such as naltrexone to treat alcoholism by having the person take the medication about an hour before they drink alcohol, and only then, in order to avoid side effects that arise from chronic use."

Here's a major, relatively recent study of Vivitrol:

Extended-Release Naltrexone to Prevent Opioid Relapse in Criminal Justice Offenders

N Engl J Med 2016; 374:1232-1242
March 31, 2016
DOI: 10.1056/NEJMoa1505409
This was a randomized trial in which the Vivitrol group was compared to a group that got "usual treatment," which was "counseling," not methadone or buprenorphine.
Here's an earlier paper which describes the study in more detail, including the fact that users of methadone or buprenorphine were excluded from the study:

As a side note, I find it hard to beleive that the several (US) FDA reviews have all relied on a single (unethical) Russian study. (Unethical in the sense that ethics dictate the "best available therapy" be used as the control, any other study design couldn't be approved in the USA and many other countries.) 216.96.77.183 ( talk) 00:02, 5 November 2015 (UTC)
Dear Jytdog:
I acknowledge that my edits at 17:50 and 18:01 today might have been annoying edits. (I never try on purpose to make annoying edits, but I've probably made quite a few annoying edits anyway.) But were they truly edit warring, and did they truly merit the {{ uw-3rr}} final notice with an ominous-looking red Stop sign icon which you posted on my talk page?

The article says: "The Sinclair method is a method of using opiate antagonist such as naltrexone to treat alcoholism by having the person take the medication about an hour before they drink alcohol, and only then". (Emphasis mine.) I'm no doctor, and I'm no expert, but "only then" seems to me like it might be too conservative. It may cost the patient some extra money, but in practice, I still think it could be a good safeguard during early sobriety for the patient to take naltrexone every morning, in case they forget to take it before their usual evening drinking session begins. No? Thanks in advance, TealHill ( talk) 18:20, 29 September 2016 (UTC)
Dear all. The article says: "The Sinclair method is a method of using opiate antagonist such as naltrexone to treat alcoholism by having the person take the medication about an hour before they drink alcohol, and only then, in order to avoid side effects that arise from chronic use." (Emphasis mine.) User:Jytdog, you wrote the bit about side effects; thank you for writing that. You added in the edit summary: "[I]f you read the source you could have added this yourself". Dear all: Which source? Which side effects? (I did look at one of the two cited articles but had trouble understanding it. I don't even have a university degree, let alone a med-school diploma or PhD. I'm just an interested addict.) Thanks in advance, TealHill ( talk) 18:20, 29 September 2016 (UTC)
The Shader ref - Shader RI (August 2003). "Antagonists, Inverse Agonists, and Protagonists". Journal of Clinical Psychopharmacology. 23 (4): 321–322. doi: 10.1097/01.jcp.0000087502.38434.6c. PMID 12920405. -- was used to support the content that naltrexone is a mu, kappa, and to a lesser extent, delta antagonist. i just read that paper. it is weird little thing, kind of a reflection, but it actually says that naltrexone is probably an inverse agonist at mu. the content said nothing like that. i added a ref that does support that content, a 2015 review PMC 4600601.
because it is a weird little paper I am not sure we should source the inverse agonist thing from it, but just wanted to mention this. Jytdog ( talk) 02:21, 14 November 2016 (UTC)
Here's a major, relatively recent study of Vivitrol:
http://www.nejm.org/doi/full/10.1056/NEJMoa1505409
Extended-Release Naltrexone to Prevent Opioid Relapse in Criminal Justice Offenders
Joshua D. Lee, et al.
N Engl J Med 2016; 374:1232-1242
March 31, 2016
DOI: 10.1056/NEJMoa1505409
This was a randomized trial in which the Vivitrol group was compared to a group that got "usual treatment," which was "counseling," not methadone or buprenorphine.
Here's an earlier paper which describes the study in more detail, including the fact that users of methadone or buprenorphine were excluded from the study:

If you use a search for the generic name you will find lots of newer reviews [1]. Doc James ( talk · contribs · email) 20:35, 1 April 2017 (UTC)
This article states that naltrexone is an antagonist at the mu opioid receptor, but this is misleading. It is agreed that naltrexone is a partial inverse agonist (as any basic Google scholar search will confirm), which is an important distinction. — Preceding unsigned comment added by 24.213.246.226 ( talk) 17:27, 27 April 2017 (UTC)
We already note this a bit in the article, but NPR ran an article on Vivitrol. Could be a useful source for society and culture.

Needs to be written in reasonably easy to understand English. Terms such as " competitive antagonist of the opioid receptors" is not. Doc James ( talk · contribs · email) 00:42, 7 November 2017 (UTC)
The Sinclair Method link just redirects you back to the section it's mention within (the part on alcoholism) — Preceding unsigned comment added by 2601:500:4100:2FC0:95CB:4821:521A:81DA ( talk) 03:49, 30 October 2019 (UTC)
