Talk:Carfentanil

message: I'd just like to point out that Ohmefentanyl has an isomer (F9204) that is 13KX morphine. There is also an isomer mixture of Ohmefenanyl that has a reported potency in the region of 20-50KX morphine. More recent studies point to analogue such as fluoro-OMF that is even more potent. Perhaps a new section needs to be opened up to clarify this as clealry there are is some controversy over the strongest opioid or at the very least we are not 100% clear on the issue.

(moved from main article):
I think this whole page is full of bugs. It might be good reading for a very superficial account though. I have read the reference and no where does it provide conclusive evidence that the gas was infact carfentanil although I am not saying it wasnt, I am just saying that such claims should only be construed as being speculative. (unsigned by Nuklear)
:Can you give more information on Ohmefentanyl and the related analogs you're talking about? Specifically, structural diagrams and citations would be preferable; you may want to consider creating articles about these compounds. Once we have sufficient sources for your claims I'll be happy to edit this article to include them. --Bk0 (Talk) 01:07, 9 December 2005 (UTC)
replies: text: Nuklear The British chemical and biological defense labs at Porton Down, England actually showed that residues on three British hostages' clothing and in one hostage's urine showed positive for carfentanil and remifentanil and negative for fentanyl, 3-methyl fentanyl and about five other fentanyl analogues. That demolishes the New York Daily News and Washington Post articles saying it was probably 3-methyl fentanyl, and is very embarrassing to the Russian Minister of Health at the time, who said it was fentanyl. Here's their article in the Journal of Analytical Toxicology, November 2012, pp 647–656 volume=36,issue=9 loupgarous (talk) 21:35, 12 April 2017 (UTC)
thread_title: Strongest opioid?

message: The Moscow Theater section previously said that there were over 125 confirmed casualties. Looking at the main article, there were about 130 deaths. As explained by Casualties, the term refers to deaths and injuries, not just fatalities, so 125 casualties is at best imprecise (how many of the casualties were fatalities), and at worst, a significant understatement of the number of casualties. I've corrected this to "deaths". The only verification I have for this is the main article; if this is not actually the case, please discuss here. Arathald (talk) 07:33, 4 August 2013 (UTC)
thread_title:  Casualties vs Deaths 

message: In the section "...Toxicity Levels" there are numbers for LD50 & AD50, but they are not associated with units, such as milligram/kg, microgram/kg, or nanogram/kg.  That's an ambiguity factor of 10^6.  Is it deliberate? (I prefer to be fully informed, but can imagine temporary alternatives). jimswen (talk) 18:04, 26 May 2017 (UTC)
thread_title:  LD50 omits units 

message: Does anybody know if this drug has a legitimate medical or veterinary use? The article doesn't list any at present. I've seen unsubstantiated claims that it is used to knock out large animals such as elephants, but there are no reliable sources supporting this that I can find. Terms such as "elephant tranquiliser" or "horse tranquiliser" are often used in sensationalist tabloid stories about street drugs. --Ef80 (talk) 23:00, 1 August 2017 (UTC)

replies: text: I was wondering the same thing. As far as I've read, it is (legally) only used in vet offices for large animals like you said. Why is there no mention of what it purpose is in the article? It is being produced, there has to be a reason why they are producing it other than for illicit use.Zdawg1029 (talk) 06:00, 18 August 2017 (UTC)

text: The US National Library of Medicine's PubChem Open Chemistry Database's entry on carfentanil says "It is marketed under the trade name Wildnil as a general anaesthetic agent for large animals. Carfentanil is intended for large-animal use only as its extreme potency makes it inappropriate for use in humans".  That's a good secondary source meeting WP:RS which describes carfentanil's legitimate veterinary use and also mentioning why it has no legitimate use in humans. loupgarous (talk) 17:24, 1 November 2017 (UTC)
thread_title:  Legitimate use? 

message: The boston globe reference to its lethality is a dead link. I found the link to the article here. https://www.bostonglobe.com/metro/2017/11/15/comparing-lethality-and-potency-opioid-drugs/6iEmKXzFDc2rjg9IIZeXWP/story.html I don't know enough about editing wikipedia to do it myself.  — Preceding unsigned comment added by 2607:FCC8:C2C0:E2F0:5D76:91C0:71A1:AC18 (talk) 20:13, 9 February 2019 (UTC)
