I would say that the out of body experience description is accurate in that when I was a novice user in my teens I had originally thought that Ketamine would put me to sleep. After having insufflated (snorted) a dose of approximately 0.5 grams of very pure substance (Ketaset), I and my companion experienced an intense experience where the room appeared to take the shape of a bowl which consisted of a maze of circuitry in which we were embedded, and left outside ourselves to view the two of us in this condition.
-I'd have to agree with this person. Though I didn't use it recreationally, I was on it intravenously while recovering from a grade 3 compound fracture (eventually the limb was removed). Point is, one evening I believed I was participating in a live action video game and everytime I opened my eyes I had to start the "level" over but I kept opening them because there was something that was scaring my pants off. Apparently I tried to climb out of bed several times and started speaking to the nurses in a variety of accents (so I'm told). During the day I entertained myself with a mirror, a comb, and my heart monitor.-

While Ketamine is a relatively safe drug (physically speaking anyway), as mentioned this article could do with some safety information. In particular, ketamine's (and other selected dissociative's) neuroprotective effects are worth mentioning briefly. These are NMDA receptor glutamate-block mediated, and it would appear (check Medline) that these neuroprotective features may assist in reducing stroke and CVA glutamate excitatory damage to neural tissues. There is considerable research in this area.
12:00, 1 January 2013 (UTC)
I hadn't heard of this particular method of use before, and I'm not sure it's common, or even feasable. Perhaps the (original?) author had confused Ketamine with its dissociative cousin PCP? Since this doesn't seem to be a common use, maybe it should be removed. Overand 05:01, 10 July 2005 (UTC)
It is wasteful, but it most certainly can be done.
I have smoked it, but did not experience any effect. it tasted like burning plastic, and so smoking should probably not be mentioned, as i am relatively sure what we are inhaling when we burn ketamine is quite unhealthy indeed.
As with most pharmaceutical compounds, you wouldn't want to burn the HCl salt, but you could vaporize the freebase oil. In theory, you should be able to burn the HCl salt with another smoking medium and get some effect, but you would be mostly burning the molecule, as the boiling point is too close to the temperature that it burns at.
As with similar articles, this should not be listed as a valid method of ingestion.
I have smoked it and know at least one other who has smoked it, I mixed it with another medium as described above I will not describe more details as I do not want that information to be easily available. My experience was as follows; it tastes disgusting (burning plastic as above) and there was an extreme psychoactive effect which was impossible to describe and deeply unpleasant. I don't know of any relevant sources for this I will keep an eye out and make an edit if I find one. Dayliterobbery ( talk) 04:22, 10 October 2013 (UTC)

I'd like to have clarification on the statement in the article that ``Intravenous self-injection of ketamine is very dangerous. Asking here because a request for clarification on this unqualified, subjectively worded, and not necessairily self-evident claim with a tag was summarily deleted. 213.93.230.146 ( talk) 08:21, 18 June 2009 (UTC)
What are you talking about ketamine is very safe to inject thats why they use it on car crash victims with no medical history. Psychonaught ( talk)
You're missing the point; "IV self-injection". NB the SELF portion of the administration. Recreational IV drug abuse is universally accepted as dangerous, particularly for centrally-acting, highly addictive substances that lower accurate perception. IV administration is the preferred method of hospital dosing as it allows accurate monitoring of blood levels, and in this setting is considered safe. Corymichael780 ( talk) 14:44, 25 March 2010 (UTC)
From what I've read here and other places it seems ketamine is surprisingly safe in itself. People seem to be confused about this sometimes, citing instances where a person on ketamine has died or been injured. That is caused by the behavioral effects of the drug, causing someone to walk in front of a bus, etc. Drugs like PCP, "Bath Salts", Bromo-Dragonfly, however have definite lethal dose levels. — Preceding unsigned comment added by 66.68.207.144 ( talk) 18:29, 31 May 2012 (UTC)
Intravenous ketamine which is self administered is in fact dangerous. This is due to the rapidness of ketamine's onset. Dissociation occurs very quickly with IV ketamine, and often times the body has produced a profound analgesic effect, especially at the site of the injection. The danger inlies when an individual becomes dissociated with the syringe still in their vein, perhaps with only a portion of the solution injected. A combination of poor coordination and high analgesia produce a scenario in which the individual could easily hurt themselves, and worse yet they may pass out before they are able to seek help. If platelets clog the syringe partway through the injection, then the likelihood of becoming dissociated before the syringe is removed increases dramatically. The danger is not like heroin, where one could inject too much and overdose ultimately leading to O2 deprivation and death. If a recreational user is determined to use ketamine intravenously, it would be safer to have a third party administer the drug. Alternatively intramuscular injection might replace intravenous injection if safety is a concern. Excessive doses of ketamine will cause a deficit in cognitive functioning, but is actually neuroprotective and quite safe so long as the individual isn't operating machinery.
Also if the ketamine is prepared from a liquid prescription, then one may wish to dilute the ketamine before intravenous use. Studies have shown that undiluted ketamine hydrochloride in solution can kill live bladder cells when directly applied. This was likely due to the solution being kept at such a low pH[3.7 if not mistaken] to increase potency, and dilution should prevent any type of damage. No studies have yet to use diluted ketamine solution in bladder cell testing, an experiment which could provide some clarity on the issue of possible bladder damage. Without this diversity the current studies still hold bias.

there are dangers; perhaps i will edit them in:
http://www.erowid.org/chemicals/ketamine/ketamine_health.shtml
I'm currently undergoing IV ketamine treatment for relief of pain from Reflex Sympathetic Dystrophy (RSD), which is due to wind-up or sensitization of the central nervous system, although the exact mechanisms responsible are still not understood. The first treatment was 40 mg/hr for 5 days in the intensive care unit on a neurology ward. Booster treatments are 10 mg/hr for 4 hrs on 2 consecutive days. Patients have to have a full cardiac work-up prior to, and are hooked up to a heart monitor during treatment because ketamine can cause extra stress on the heart. It also causes anxiety, which raises blood pressure and there is definitely decreased coordination. At 40 mg/hr they draw blood every day to monitor liver function as well.
Another type of danger :) The Dr had the hospital remove phones from these patient rooms, as some were making banking decisions or purchases from QVC while "under the influence" - could make for some unpleasant surprises!

The fact that it's in the same family as PCP should show evident dangers of it. But yes, from what I know, it's addictive and dangerous. Tolerance + addiction = bad. 4.234.51.29 21:50, 25 January 2007 (UTC)
It would hardly be used to treat addiction if it were very addictive. — While this does make sense logically, some drugs used to treat addiction are chemically similar to the drug of addiction or otherwise have similarly addictive properties. However, due to the different context or circumstance in which it is taken, these drugs might differ in their addictive dynamics - for example taking heroin to kill time or pain vs. taking buprenorphine to remove the negative effects of heroin withdrawal. It depends upon the associations one makes between a drug and a stimulus/what triggers the desire for it. — Preceding unsigned comment added by 75.158.98.81 ( talk) 09:06, 29 January 2012 (UTC)
As an anaesthetic, its about the safest there is. Yes, it has drawbacks (addiction the only really common one...) but when you look at it in comparison with, for example, thiopental, or even propofol, its incredibly safe! Of course, in some ways that makes it worse if its abused - users don't display the physical breakdown that may allow diagnosis of addiction to other drugs. ( Dlh-stablelights 20:31, 8 June 2007 (UTC))
It is extremely dangerous if used daily in high doses and on a daily/almost daily basis including physical pain ("cramps"), urinary problems from cystitis like symptoms to bladder removal, mood swings, psychotic episodes and more some of which aren't even mentioned in this article or the recreational use article I have sources to make a lot of relevant edits and will have a look for more to prove what I already know from a decade of addiction but do not have sources to hand but I do not know which article to start in if anyone could help I would much appreciate it Dayliterobbery ( talk) 04:43, 10 October 2013 (UTC)
The history section I just added needs some attention, and I think the article could stand to have the history more unified, leaving the other sections free of background information.

COPS NAB COUPLE IN DRUG CASE
Moraine police on Tuesday arrested a Miami Twp. couple on several charges involving the designer "party" drug Ecstasy and LSD, a hallucinogenic.
The arrests of David Jason Day, 24, and his wife, Tonya Inez Henson Day, 22, of 4869 Delba Drive, capped a three-month investigation by Moraine police and the Food and Drug Administration into those drugs, along with Ketamine, a powerful mind-altering anesthetic, chemically similar to PCP. Moraine Police Detective Sgt. Tracy Harpster said Ketamine isn't federally scheduled at this time so Day wasn't charged with possession of the drug. However, he could be charged in New York, where he allegedly picked up the vials, and where possession of the drug without a prescription is illegal.
Day was charged with conspiracy to traffic in Ecstasy, two counts of corrupting another with drugs, and trafficking in LSD. One count of corrupting stems from the sale of LSD to a juvenile. Day's wife was charged with felony permitting drug abuse; she is accused of taking part in drug deals with her 17-month-old son present.
Both were arraigned Wednesday before Montgomery County Common Pleas Judge David Gowdown and released on bond.
Day helps operate the Reptile House, which has a store at 121 N. Springboro Pike and a warehouse at 2311 Dryden Road. Police confiscated items from the warehouse and searched the couple's home, seizing money, drugs and the couple's car, Harpster said.
Ecstasy (MDMA) is a synthetic drug with both hallucinogenic and amphetamine-like properties.
Ketamine is known on the street as "K" or "Special K" or "KitKat." Street value of the Ketamine was $30,000, Harpster said. The drug is manufactured in liquid form primarily as a veterinary tranquilizer, but is sold on the street in pill or crystalline powder form.
Use of the drug locally seems rare. "We aren't familiar with it," said Bill Wharton, administrative assistant, Montgomery County Combined Health District. "No one has mentioned using it," said Sharon Taylor, who sits on the screening panel of Project Cure, a drug treatment center. — Preceding unsigned comment added by 107.9.9.161 ( talk) 00:23, 18 October 2013 (UTC)

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Ketamine's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

The article contains,
"A review article in 2013 concluded that "despite limitations in the breadth and depth of data available, there is evidence that ketamine may be a viable option for treatment-refractory cancer pain".[17]"
The source (Breedlau et al. 2013) is a good one, it is a systematic review and synthesis of literature, recent and in a decent journal. I just don't know if in the "Use" section (as opposed to "Research") WP should be talking about what "may be a viable option". I don't have access to the full text but I note they included 5 RCT's, and 6 uncontrolled studies. I also note that the 2012 Cochrane review found only 2 RCT's that met criteria and using higher standards didn't include any uncontrolled studies. The conclusion of the Cochrane review was,
"Current evidence is insufficient to assess the benefits and harms of ketamine as an adjuvant to opioids for the relief of cancer pain."
This seems more appropriate for WP and is a higher level of MEDRS.

The lead currently contains a single sentence on recreational use, "Recreational use has led to high-profile deaths.[7]" This does not seem an adequate summary of the content. Granted there is a stand alone article Recreational use of ketamine but this article contains enough information on recreational use to support a second sentence summarizing recreational use as due. Something like, "Ketamine has been used as a recreational drug since the 1970s, increasingly so to the end of the 20th century and as a result it's use has been restricted in many (some, several?) countries." The existing sources and content certainly support at least that. Due/Undue, appropriate? Input from medical editors appreciated as I am not extensively experienced in editing articles about drugs with medical and recreational use. - - MrBill3 ( talk) 08:47, 27 July 2014 (UTC)
More, no. Better, yes. If you put recreational use in the context of medicinal benefit, then yes. If the impression left on the reader is "horse tranquilizer and drug of abuse", that is not a factual representation of this drug. If 99.5% of the medication produced is used in medical settings, what is the agenda behind emphasizing the aspects of abuse?
I would support a full paragraph on abuse, were it to put abuse in the proper perspective. Abuse is a problem now, it is only going to get worse as people recognize it as a possible treatment for their emotional ills. Self-medication with ketamine is a sure path to abuse, and I would support factual and documented entries to help the reader make good judgments.
I do know more about this medication than the average bear - please give me the opportunity to share:
1. Ketamine is a very unique substance in that its LD 50 is estimated to be 450 times its therapeutic dose. The practical effect of this is that people abuse it at such high doses that the effects they experience are not relevant to the effects at lower dosages. The abuse dosage of ketamine is roughly 100 times the medicinal dose. 12 times the normal "dose" of water will kill you. Ketamine is pretty unique. Every reference to effect or side effect needs to reference the dose of the observation or it is a very misleading entry, for this drug.
2. The recreational deaths in the citing in the first paragraph are not due to overdose. They are due to unsupervised use of an anesthetic - guess what, that is not a good idea in any circumstance. Pointing out that people die when they self administer an anesthetic is like pointing out people die when they jump off a cliff. I am pretty sure as it stands this does not belong in wiki. But as said elsewhere, I am content leaving the community to judge.
3. This is a generic medication competing against existing and promised patented products. There is a huge financial benefit to some players for ketamine to be seen unfavorably. I would suggest that all contributions include a full COI, as I have done. I notice nothing from you, MRBill3, despite all of the hours you have clearly spent recently editing the page. Either you are the most saintly person on earth, or perhaps you have something more to share? Geraldwgaines ( talk) 03:28, 28 July 2014 (UTC)
I removed,
"Indeed, a review published in 2009 found no evidence of ketamine-induced neuron death in humans. [1]
The article actually discusses the FDA call to investigate the possibility discussing problems with extrapolating animal studies to humans and stating in it's summary,
"Although it is beyond dispute that ketamine can induce neuronal death in rodents and other animals, there is thus far no evidence that such an effect occurs in humans. Indeed, such a premise is at complete odds with the wealth of human experience with this agent. However, now that this question has been raised, we are obligated to carefully investigate."
It goes on to describe study models to investigate this question. Not a finding of no evidence in humans but a call to actually investigate. The paper describes the lack of study. It also discusses concerns about,
"children may be experiencing unrecognized central nervous system damage and perhaps cognitive sequelae"
It cites the FDA conclusion,
"the potential threat was sufficient to represent a public health concern."
The introduction states,
"This article discusses the limitations of the underlying animal research on which the FDA and NIH investigations are based, the challenges in extrapolating such data to humans, the need for further animal and human investigations, and the potential adverse effect on clinical practice that might result should the use of ketamine be restricted or the drug removed from the market."

I'd like to thank all of the well-intended editors who have deleted or changed entries I added that did not meet wiki standards. I'll always appreciate that, so please never stop.
That said, in real life we learned today that we recently lost our first patient, to a physical illness. We count this case as "passive suicide". Anyone who is data oriented could take this loss and the hundreds and hundreds of people-months of no incidences of loss/hospitalization/suicide attempts in our sub-population of over median beck 40 and you will realize the efficacy of ketamine. We failed to stabilize the patient earlier this year, but with what we know after 400 more infusions the patient would have had a great chance to recover from depression. We are running at a close to 90% response rate now. This is what is happening on the ground. I need to get back to my day job of being the data nerd that is evaluating all of this and the patient advocate who gets to explain why we don't know more yet.
I would ask of this group, that were I to fund an organization like the ACLU or the National Alliance of the Mentally Ill, to edit this page for accuracy and to seek verifiable sources of data that might help the general public, would that be welcomed here?

Thanks Jytdog, for others I am not being sarcastic and truly appreciative of constructive input. There seems to be a difference of opinion about how the Conflict of Interest Rules Work here. In most situations out in the real world, and according to my reading of Wiki rules, COI's, including compensation, are accepted as inevitable and largely untraceable in the normal course of life - the key is disclosure and being held to the same standard of evidence with your audience aware of the COI - with the role of other editors to validate the entries that are suggested. I have changed the original post to emphasize "edit this page for accuracy and to seek verifiable sources of data" to point out that I believe the activity as described by any entity is exactly the wiki mission. Am I missing something? Geraldwgaines ( talk) 13:44, 25 July 2014 (UTC)
Bluerasberry, thanks for your response, it is very helpful in understanding the environment at wiki. Maybe this will help regarding my efforts here - I am using my own name and there is this thing called google which covers me quite nicely. If you dig, you'll find that my data changed the telecommunications laws of this country, twice. And the MMJ laws of Arizona. I actually know how to use statistics to tell the truth, a rare skill these days. I simply do not have the time to edit this page in person. I've already got the ACLU signed up to do a Freedom of Information Act request to gain ketamine data from the government - they or someone else would be happy to edit this page as I've described. This effort is not about Advocacy, it is about civil liberties (the right of citizens to know what their government knows) and specifically at Wiki a page that has been driven by interests that did not want an accurate portrayal of ketamine. Ask 10 people about ketamine, and 8 will say it is a horse tranquilizer and drug of abuse. Two weeks ago the wiki page reinforced that image. Now it does so to a lesser degree. My sole objective is to have the definition of ketamine accurately reflect the available data on medicinal and abuse issues. Geraldwgaines ( talk) 18:30, 25 July 2014 (UTC)

A 2003 Cochrane review concluded,
"With many other safer analgesics available on the market today and no head-to-head trials suggesting superior efficacy, our review does not support the use of nefopam in patients with RA."
But did find,
"There is weak evidence that nefopam is an effective analgesic when compared with placebo in patients with RA, over four weeks." and "Nefopam appears to have moderate analgesic efficacy in patients with active RA who are not taking other analgesic medications."
While pointing out problems with patients ability to tolerate and possible side effects. The considered the studies they reviewed to have a high risk of bias. Should this be mentioned in an Other conditions subsection of the Research section?

I think an "Other conditons" subsection could be added to the "Research" section. Ketamine is being studied as a treatment for asthma. Two recent (2012, 2014) reviews have been published. The evidence is negative or low level but continued research is suggested. Should this be added or is this a case for WP:there is no deadline? My thought is if it is worthy of review by two high quality sources...
The 2012 Cochrane review concluded, "The single study on non-intubated children with severe acute asthma did not show significant benefit and does not support the case studies and observational reports showing benefits of ketamine in both non-ventilated and ventilated children." Suggesting that quality studies were needed to prove a benefit for ketamine use in children with asthma.
While a 2014 Expert Reviews of Respiratory Medicine" review concluded, "In summary, there is only a low level of evidence that ketamine may be beneficial in patients with severe asthma exacerbations who are mechanically ventilated. Further investigations are needed to determine the impact of ketamine in intubated and non-intubated patients with status asthmaticus."
Suggested text, "Ketamine is being studied for the treatment of asthma. No benefits have been clearly demonstrated but further research has been suggested."

Thanks everyone for putting some sources out there. A brief note to consider. Most studies note in top line results the raw dose of ketamine delivered without mentioning the time period over which the dose was given. The first pass half life of ketamine is less than 20 minutes. A .5 mg/kg dose dose of ketamine given over 10 minutes affects the mind very differently than the same total dose given over 40 minutes. The various studies are not consistent in their flow rate and need to be so referenced to be accurate. The relevant metric for comparison of ketamine effects for emotional illnesses is mg/kg/hr.

The claim that side effects occur "as the medication wears off" doesn't seem to have any basis. There's no indication in either source (both drugs.com pages) when the side effects occur. This is problematic since it implies lingering effects that may not exist and are not indicated in the references. (Though the special note in ref [4] specifically indicates that while some side effects may recur over a 24h period, no residual psych. effects are known.) Unless anyone has any further info on the side effects, I'd say remove the "as the medication wears off" portion. ParoXoN ( talk) 23:11, 16 February 2016 (UTC)

Numerous studies have emerged stating Ketamine's benefit for treatment-resistant depression, and this is perhaps the most consequential development pertaining to this drug in recent memory. However, the depression section of this article is terse with descriptions of efficacy relying on outdated studies. The article does not describe how the drug acts on depression (hypothesized MOA), the emergence of ketamine clinics delivering infusions to treatment resistant patients, or Ketamine's relationship to the development of glutamatergic antidepressants. The articles on ketamine's enantiomers are even more fully fleshed-out in this respect. 68.185.202.126 ( talk) 04:38, 26 April 2016 (UTC)ddiamondds
Hi! After seeing it on the NIH Director's blog, I added some information about indications that ketamine's fast-acting antidepressant effects may be caused by one of its metabolites, which doesn't have the same potential for abuse. (Study published in Nature.) It's been integrated into the article for hydroxynorketamine, the metabolite in question. The revert message says to look at WP:MEDRS; this is recently published, so it doesn't appear in any reviews yet, but it seems important enough to include at least some note of it. ("If conclusions are worth mentioning [...] they should be described appropriately as from a single study".) Am I missing something here? Thanks! grendel| khan 00:59, 15 May 2016 (UTC)
Is Scotland's drug classification different from rest of UK's?-- Armanikoka ( talk) 00:03, 21 July 2016 (UTC)
In the Anaesthesia section the statement "It is sometimes possible to perform ketamine anesthesia without protective measures to the airways." is not referenced. There does not appear to be a readily apparent source for this statement. This is often the case in animal anaesthesia where Ketamine or a combination with it and another anaesthetic is used without airway support. However in human anaesthesia, it does not appear to be used without airway support due to its pro-salivary properties: https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/25886322/
In the Vetinary Medicine section, the statement "Ketamine is used to manage pain among large animals, though it has less effect on bovines." is not referenced. There does not appear to be any scientific articles that make note of a lesser effect on bovines relative to other animals. Given the complexity of inter-species dose scaling, I wonder if this statement is useful. — Preceding unsigned comment added by Yossarian54 ( talk • contribs) 03:52, 1 February 2017 (UTC)

I would say that the out of body experience description is accurate in that when I was a novice user in my teens I had originally thought that Ketamine would put me to sleep. After having insufflated (snorted) a dose of approximately 0.5 grams of very pure substance (Ketaset), I and my companion experienced an intense experience where the room appeared to take the shape of a bowl which consisted of a maze of circuitry in which we were embedded, and left outside ourselves to view the two of us in this condition.
-I'd have to agree with this person. Though I didn't use it recreationally, I was on it intravenously while recovering from a grade 3 compound fracture (eventually the limb was removed). Point is, one evening I believed I was participating in a live action video game and everytime I opened my eyes I had to start the "level" over but I kept opening them because there was something that was scaring my pants off. Apparently I tried to climb out of bed several times and started speaking to the nurses in a variety of accents (so I'm told). During the day I entertained myself with a mirror, a comb, and my heart monitor.-

While Ketamine is a relatively safe drug (physically speaking anyway), as mentioned this article could do with some safety information. In particular, ketamine's (and other selected dissociative's) neuroprotective effects are worth mentioning briefly. These are NMDA receptor glutamate-block mediated, and it would appear (check Medline) that these neuroprotective features may assist in reducing stroke and CVA glutamate excitatory damage to neural tissues. There is considerable research in this area.
12:00, 1 January 2013 (UTC)
I hadn't heard of this particular method of use before, and I'm not sure it's common, or even feasable. Perhaps the (original?) author had confused Ketamine with its dissociative cousin PCP? Since this doesn't seem to be a common use, maybe it should be removed. Overand 05:01, 10 July 2005 (UTC)
It is wasteful, but it most certainly can be done.
I have smoked it, but did not experience any effect. it tasted like burning plastic, and so smoking should probably not be mentioned, as i am relatively sure what we are inhaling when we burn ketamine is quite unhealthy indeed.
As with most pharmaceutical compounds, you wouldn't want to burn the HCl salt, but you could vaporize the freebase oil. In theory, you should be able to burn the HCl salt with another smoking medium and get some effect, but you would be mostly burning the molecule, as the boiling point is too close to the temperature that it burns at.
As with similar articles, this should not be listed as a valid method of ingestion.
I have smoked it and know at least one other who has smoked it, I mixed it with another medium as described above I will not describe more details as I do not want that information to be easily available. My experience was as follows; it tastes disgusting (burning plastic as above) and there was an extreme psychoactive effect which was impossible to describe and deeply unpleasant. I don't know of any relevant sources for this I will keep an eye out and make an edit if I find one. Dayliterobbery ( talk) 04:22, 10 October 2013 (UTC)

What are you talking about ketamine is very safe to inject thats why they use it on car crash victims with no medical history. Psychonaught ( talk)
You're missing the point; "IV self-injection". NB the SELF portion of the administration. Recreational IV drug abuse is universally accepted as dangerous, particularly for centrally-acting, highly addictive substances that lower accurate perception. IV administration is the preferred method of hospital dosing as it allows accurate monitoring of blood levels, and in this setting is considered safe. Corymichael780 ( talk) 14:44, 25 March 2010 (UTC)
From what I've read here and other places it seems ketamine is surprisingly safe in itself. People seem to be confused about this sometimes, citing instances where a person on ketamine has died or been injured. That is caused by the behavioral effects of the drug, causing someone to walk in front of a bus, etc. Drugs like PCP, "Bath Salts", Bromo-Dragonfly, however have definite lethal dose levels. — Preceding unsigned comment added by 66.68.207.144 ( talk) 18:29, 31 May 2012 (UTC)
Intravenous ketamine which is self administered is in fact dangerous. This is due to the rapidness of ketamine's onset. Dissociation occurs very quickly with IV ketamine, and often times the body has produced a profound analgesic effect, especially at the site of the injection. The danger inlies when an individual becomes dissociated with the syringe still in their vein, perhaps with only a portion of the solution injected. A combination of poor coordination and high analgesia produce a scenario in which the individual could easily hurt themselves, and worse yet they may pass out before they are able to seek help. If platelets clog the syringe partway through the injection, then the likelihood of becoming dissociated before the syringe is removed increases dramatically. The danger is not like heroin, where one could inject too much and overdose ultimately leading to O2 deprivation and death. If a recreational user is determined to use ketamine intravenously, it would be safer to have a third party administer the drug. Alternatively intramuscular injection might replace intravenous injection if safety is a concern. Excessive doses of ketamine will cause a deficit in cognitive functioning, but is actually neuroprotective and quite safe so long as the individual isn't operating machinery.
Also if the ketamine is prepared from a liquid prescription, then one may wish to dilute the ketamine before intravenous use. Studies have shown that undiluted ketamine hydrochloride in solution can kill live bladder cells when directly applied. This was likely due to the solution being kept at such a low pH[3.7 if not mistaken] to increase potency, and dilution should prevent any type of damage. No studies have yet to use diluted ketamine solution in bladder cell testing, an experiment which could provide some clarity on the issue of possible bladder damage. Without this diversity the current studies still hold bias.

there are dangers; perhaps i will edit them in:
http://www.erowid.org/chemicals/ketamine/ketamine_health.shtml
I'm currently undergoing IV ketamine treatment for relief of pain from Reflex Sympathetic Dystrophy (RSD), which is due to wind-up or sensitization of the central nervous system, although the exact mechanisms responsible are still not understood. The first treatment was 40 mg/hr for 5 days in the intensive care unit on a neurology ward. Booster treatments are 10 mg/hr for 4 hrs on 2 consecutive days. Patients have to have a full cardiac work-up prior to, and are hooked up to a heart monitor during treatment because ketamine can cause extra stress on the heart. It also causes anxiety, which raises blood pressure and there is definitely decreased coordination. At 40 mg/hr they draw blood every day to monitor liver function as well.
Another type of danger :) The Dr had the hospital remove phones from these patient rooms, as some were making banking decisions or purchases from QVC while "under the influence" - could make for some unpleasant surprises!

The fact that it's in the same family as PCP should show evident dangers of it. But yes, from what I know, it's addictive and dangerous. Tolerance + addiction = bad. 4.234.51.29 21:50, 25 January 2007 (UTC)
It would hardly be used to treat addiction if it were very addictive. — While this does make sense logically, some drugs used to treat addiction are chemically similar to the drug of addiction or otherwise have similarly addictive properties. However, due to the different context or circumstance in which it is taken, these drugs might differ in their addictive dynamics - for example taking heroin to kill time or pain vs. taking buprenorphine to remove the negative effects of heroin withdrawal. It depends upon the associations one makes between a drug and a stimulus/what triggers the desire for it. — Preceding unsigned comment added by 75.158.98.81 ( talk) 09:06, 29 January 2012 (UTC)
As an anaesthetic, its about the safest there is. Yes, it has drawbacks (addiction the only really common one...) but when you look at it in comparison with, for example, thiopental, or even propofol, its incredibly safe! Of course, in some ways that makes it worse if its abused - users don't display the physical breakdown that may allow diagnosis of addiction to other drugs. ( Dlh-stablelights 20:31, 8 June 2007 (UTC))
It is extremely dangerous if used daily in high doses and on a daily/almost daily basis including physical pain ("cramps"), urinary problems from cystitis like symptoms to bladder removal, mood swings, psychotic episodes and more some of which aren't even mentioned in this article or the recreational use article I have sources to make a lot of relevant edits and will have a look for more to prove what I already know from a decade of addiction but do not have sources to hand but I do not know which article to start in if anyone could help I would much appreciate it Dayliterobbery ( talk) 04:43, 10 October 2013 (UTC)

COPS NAB COUPLE IN DRUG CASE
Moraine police on Tuesday arrested a Miami Twp. couple on several charges involving the designer "party" drug Ecstasy and LSD, a hallucinogenic.
The arrests of David Jason Day, 24, and his wife, Tonya Inez Henson Day, 22, of 4869 Delba Drive, capped a three-month investigation by Moraine police and the Food and Drug Administration into those drugs, along with Ketamine, a powerful mind-altering anesthetic, chemically similar to PCP. Moraine Police Detective Sgt. Tracy Harpster said Ketamine isn't federally scheduled at this time so Day wasn't charged with possession of the drug. However, he could be charged in New York, where he allegedly picked up the vials, and where possession of the drug without a prescription is illegal.
Day was charged with conspiracy to traffic in Ecstasy, two counts of corrupting another with drugs, and trafficking in LSD. One count of corrupting stems from the sale of LSD to a juvenile. Day's wife was charged with felony permitting drug abuse; she is accused of taking part in drug deals with her 17-month-old son present.
Both were arraigned Wednesday before Montgomery County Common Pleas Judge David Gowdown and released on bond.
Day helps operate the Reptile House, which has a store at 121 N. Springboro Pike and a warehouse at 2311 Dryden Road. Police confiscated items from the warehouse and searched the couple's home, seizing money, drugs and the couple's car, Harpster said.
Ecstasy (MDMA) is a synthetic drug with both hallucinogenic and amphetamine-like properties.
Ketamine is known on the street as "K" or "Special K" or "KitKat." Street value of the Ketamine was $30,000, Harpster said. The drug is manufactured in liquid form primarily as a veterinary tranquilizer, but is sold on the street in pill or crystalline powder form.
Use of the drug locally seems rare. "We aren't familiar with it," said Bill Wharton, administrative assistant, Montgomery County Combined Health District. "No one has mentioned using it," said Sharon Taylor, who sits on the screening panel of Project Cure, a drug treatment center. — Preceding unsigned comment added by 107.9.9.161 ( talk) 00:23, 18 October 2013 (UTC)

The article contains,
"A review article in 2013 concluded that "despite limitations in the breadth and depth of data available, there is evidence that ketamine may be a viable option for treatment-refractory cancer pain".[17]"
The source (Breedlau et al. 2013) is a good one, it is a systematic review and synthesis of literature, recent and in a decent journal. I just don't know if in the "Use" section (as opposed to "Research") WP should be talking about what "may be a viable option". I don't have access to the full text but I note they included 5 RCT's, and 6 uncontrolled studies. I also note that the 2012 Cochrane review found only 2 RCT's that met criteria and using higher standards didn't include any uncontrolled studies. The conclusion of the Cochrane review was,
"Current evidence is insufficient to assess the benefits and harms of ketamine as an adjuvant to opioids for the relief of cancer pain."
This seems more appropriate for WP and is a higher level of MEDRS.

The lead currently contains a single sentence on recreational use, "Recreational use has led to high-profile deaths.[7]" This does not seem an adequate summary of the content. Granted there is a stand alone article Recreational use of ketamine but this article contains enough information on recreational use to support a second sentence summarizing recreational use as due. Something like, "Ketamine has been used as a recreational drug since the 1970s, increasingly so to the end of the 20th century and as a result it's use has been restricted in many (some, several?) countries." The existing sources and content certainly support at least that. Due/Undue, appropriate? Input from medical editors appreciated as I am not extensively experienced in editing articles about drugs with medical and recreational use. - - MrBill3 ( talk) 08:47, 27 July 2014 (UTC)
More, no. Better, yes. If you put recreational use in the context of medicinal benefit, then yes. If the impression left on the reader is "horse tranquilizer and drug of abuse", that is not a factual representation of this drug. If 99.5% of the medication produced is used in medical settings, what is the agenda behind emphasizing the aspects of abuse?
I would support a full paragraph on abuse, were it to put abuse in the proper perspective. Abuse is a problem now, it is only going to get worse as people recognize it as a possible treatment for their emotional ills. Self-medication with ketamine is a sure path to abuse, and I would support factual and documented entries to help the reader make good judgments.
I do know more about this medication than the average bear - please give me the opportunity to share:
1. Ketamine is a very unique substance in that its LD 50 is estimated to be 450 times its therapeutic dose. The practical effect of this is that people abuse it at such high doses that the effects they experience are not relevant to the effects at lower dosages. The abuse dosage of ketamine is roughly 100 times the medicinal dose. 12 times the normal "dose" of water will kill you. Ketamine is pretty unique. Every reference to effect or side effect needs to reference the dose of the observation or it is a very misleading entry, for this drug.
2. The recreational deaths in the citing in the first paragraph are not due to overdose. They are due to unsupervised use of an anesthetic - guess what, that is not a good idea in any circumstance. Pointing out that people die when they self administer an anesthetic is like pointing out people die when they jump off a cliff. I am pretty sure as it stands this does not belong in wiki. But as said elsewhere, I am content leaving the community to judge.
3. This is a generic medication competing against existing and promised patented products. There is a huge financial benefit to some players for ketamine to be seen unfavorably. I would suggest that all contributions include a full COI, as I have done. I notice nothing from you, MRBill3, despite all of the hours you have clearly spent recently editing the page.

I removed,
"Indeed, a review published in 2009 found no evidence of ketamine-induced neuron death in humans. [1]
The article actually discusses the FDA call to investigate the possibility discussing problems with extrapolating animal studies to humans and stating in it's summary,
"Although it is beyond dispute that ketamine can induce neuronal death in rodents and other animals, there is thus far no evidence that such an effect occurs in humans. Indeed, such a premise is at complete odds with the wealth of human experience with this agent. However, now that this question has been raised, we are obligated to carefully investigate."
It goes on to describe study models to investigate this question. Not a finding of no evidence in humans but a call to actually investigate. The paper describes the lack of study. It also discusses concerns about,
"children may be experiencing unrecognized central nervous system damage and perhaps cognitive sequelae"
It cites the FDA conclusion,
"the potential threat was sufficient to represent a public health concern."
The introduction states,
"This article discusses the limitations of the underlying animal research on which the FDA and NIH investigations are based, the challenges in extrapolating such data to humans, the need for further animal and human investigations, and the potential adverse effect on clinical practice that might result should the use of ketamine be restricted or the drug removed from the market."

I'd like to thank all of the well-intended editors who have deleted or changed entries I added that did not meet wiki standards. I'll always appreciate that, so please never stop.
That said, in real life we learned today that we recently lost our first patient, to a physical illness. We count this case as "passive suicide". Anyone who is data oriented could take this loss and the hundreds and hundreds of people-months of no incidences of loss/hospitalization/suicide attempts in our sub-population of over median beck 40 and you will realize the efficacy of ketamine. We failed to stabilize the patient earlier this year, but with what we know after 400 more infusions the patient would have had a great chance to recover from depression. We are running at a close to 90% response rate now. This is what is happening on the ground. I need to get back to my day job of being the data nerd that is evaluating all of this and the patient advocate who gets to explain why we don't know more yet.
I would ask of this group, that were I to fund an organization like the ACLU or the National Alliance of the Mentally Ill, to edit this page for accuracy and to seek verifiable sources of data that might help the general public, would that be welcomed here?

Thanks Jytdog, for others I am not being sarcastic and truly appreciative of constructive input. There seems to be a difference of opinion about how the Conflict of Interest Rules Work here. In most situations out in the real world, and according to my reading of Wiki rules, COI's, including compensation, are accepted as inevitable and largely untraceable in the normal course of life - the key is disclosure and being held to the same standard of evidence with your audience aware of the COI - with the role of other editors to validate the entries that are suggested.

Bluerasberry, thanks for your response, it is very helpful in understanding the environment at wiki. Maybe this will help regarding my efforts here - I am using my own name and there is this thing called google which covers me quite nicely. If you dig, you'll find that my data changed the telecommunications laws of this country, twice. And the MMJ laws of Arizona. I actually know how to use statistics to tell the truth, a rare skill these days. I simply do not have the time to edit this page in person. I've already got the ACLU signed up to do a Freedom of Information Act request to gain ketamine data from the government - they or someone else would be happy to edit this page as I've described. This effort is not about Advocacy, it is about civil liberties (the right of citizens to know what their government knows) and specifically at Wiki a page that has been driven by interests that did not want an accurate portrayal of ketamine. Ask 10 people about ketamine, and 8 will say it is a horse tranquilizer and drug of abuse. Two weeks ago the wiki page reinforced that image. Now it does so to a lesser degree. My sole objective is to have the definition of ketamine accurately reflect the available data on medicinal and abuse issues. Geraldwgaines ( talk) 18:30, 25 July 2014 (UTC)

"With many other safer analgesics available on the market today and no head-to-head trials suggesting superior efficacy, our review does not support the use of nefopam in patients with RA."
But did find,
"There is weak evidence that nefopam is an effective analgesic when compared with placebo in patients with RA, over four weeks." and "Nefopam appears to have moderate analgesic efficacy in patients with active RA who are not taking other analgesic medications."

I think an "Other conditons" subsection could be added to the "Research" section. Ketamine is being studied as a treatment for asthma. Two recent (2012, 2014) reviews have been published.

My thought is if it is worthy of review by two high quality sources...

Suggesting that quality studies were needed to prove a benefit for ketamine use in children with asthma.
While a 2014 Expert Reviews of Respiratory Medicine" review concluded, "In summary, there is only a low level of evidence that ketamine may be beneficial in patients with severe asthma exacerbations who are mechanically ventilated. Further investigations are needed to determine the impact of ketamine in intubated and non-intubated patients with status asthmaticus."
Suggested text, "Ketamine is being studied for the treatment of asthma. No benefits have been clearly demonstrated but further research has been suggested."
I am suggesting an "Other conditions" subsection as I expect to find more research. - - MrBill3 ( talk) 00:40, 28 July 2014 (UTC)

Thanks everyone for putting some sources out there. A brief note to consider. Most studies note in top line results the raw dose of ketamine delivered without mentioning the time period over which the dose was given. The first pass half life of ketamine is less than 20 minutes. A .5 mg/kg dose dose of ketamine given over 10 minutes affects the mind very differently than the same total dose given over 40 minutes. The various studies are not consistent in their flow rate and need to be so referenced to be accurate. The relevant metric for comparison of ketamine effects for emotional illnesses is mg/kg/hr.

If you Google Keramine you can see a lot of scams that claim it works for Drepression when it's not FDA approved for that. 65.175.243.206 ( talk) 13:53, 1 January 2015 (UTC)
In this , it is claimed that ketamine was developed (by Craig Newlands) before it was synthesized (by Calvin Stevens) which is a logical impossibility. How do you develop something before it exists? I realize that what the source says, but I am skeptical of the source, especially when other reliable sources (see for example here and here) don't mention Craig Newlands.

I have concerns about the large recent edit made by Leprof 7272 ( talk · contribs), with edit summary "Added recent statistics and references regarding deaths in young adults, 2005-2013. For section that ,ore than 95% covers governmental regulation, the heading of "Legal status" was elevated to replace the misnomer "Society and culture". Le Prof", ( diff). It seems somewhat UNDUE because of the stridency of tone and number of repetitions; also some of the refs are not compatible with WP:MEDRS. The following passage in particular strikes me as not belonging:
"…cocaine, MDMA, mephedrone and LSD can end up damaging people and some can become addict[ed], but it appears none of these drugs has the ability to wreck the body or leave users mentally marooned in the way that ketamine does. Rather than being a window into the soul, for some ketamine has turned into a way of mollifying pain or getting through the day, like heroin and diazepam."
This is referenced to a website and a newspaper. Looie496 ( talk) 14:06, 8 June 2015 (UTC)
This image would be great to have drawn by someone who has the ability to make it different enough and release it free on Wiki-media to put on the ketamine page.

Success in treatment of depression with Ketamine is optimized when it is used in conjunction with transcranial magnetic stimulation (TMS).

The claim that side effects occur "as the medication wears off" doesn't seem to have any basis. There's no indication in either source (both drugs.com pages) when the side effects occur. This is problematic since it implies lingering effects that may not exist and are not indicated in the references. (Though the special note in ref [4] specifically indicates that while some side effects may recur over a 24h period, no residual psych. effects are known.) Unless anyone has any further info on the side effects, I'd say remove the "as the medication wears off" portion. ParoXoN ( talk) 23:11, 16 February 2016 (UTC)

Numerous studies have emerged stating Ketamine's benefit for treatment-resistant depression, and this is perhaps the most consequential development pertaining to this drug in recent memory. However, the depression section of this article is terse with descriptions of efficacy relying on outdated studies. The article does not describe how the drug acts on depression (hypothesized MOA), the emergence of ketamine clinics delivering infusions to treatment resistant patients, or Ketamine's relationship to the development of glutamatergic antidepressants. The articles on ketamine's enantiomers are even more fully fleshed-out in this respect. 68.185.202.126 ( talk) 04:38, 26 April 2016 (UTC)ddiamondds
Hi! After seeing it on the NIH Director's blog, I added some information about indications that ketamine's fast-acting antidepressant effects may be caused by one of its metabolites, which doesn't have the same potential for abuse. (Study published in Nature.) It's been integrated into the article for hydroxynorketamine, the metabolite in question. The revert message says to look at WP:MEDRS; this is recently published, so it doesn't appear in any reviews yet, but it seems important enough to include at least some note of it. ("If conclusions are worth mentioning [...] they should be described appropriately as from a single study".) Am I missing something here? Thanks! grendel| khan 00:59, 15 May 2016 (UTC)

In the Anaesthesia section the statement "It is sometimes possible to perform ketamine anesthesia without protective measures to the airways." is not referenced. There does not appear to be a readily apparent source for this statement. This is often the case in animal anaesthesia where Ketamine or a combination with it and another anaesthetic is used without airway support. However in human anaesthesia, it does not appear to be used without airway support due to its pro-salivary properties: https://www.ncbi.nlm.nih.gov/pmc/articles/pmid/25886322/
In the Vetinary Medicine section, the statement "Ketamine is used to manage pain among large animals, though it has less effect on bovines." is not referenced. There does not appear to be any scientific articles that make note of a lesser effect on bovines relative to other animals. Given the complexity of inter-species dose scaling, I wonder if this statement is useful. — Preceding unsigned comment added by Yossarian54 ( talk • contribs) 03:52, 1 February 2017 (UTC)
