Carfentanil or carfentanyl, sold under the brand name Wildnil, is an extremely potent opioid analgesic used in veterinary medicine to anesthetize large animals such as elephants and rhinoceroses. [1] It is an analogue of fentanyl , of which it is structurally derivative.
Carfentanil is a synthetic opioid approximately 10,000 times more potent than morphine and 100 times more potent than fentanyl. Legalizing test strips could bring those numbers down, advocates say ...
In 2012, Riches et al. [11] found evidence from liquid chromatography-tandem mass spectrometry analysis of extracts of clothing from two British survivors, and urine from a third survivor, that the aerosol was a mixture carfentanil and remifentanil the exact proportions of which they could not determine.
Ohmecarfentanil (RTI-4614-38), also known as Ohlofentanil, is a mu opioid receptor agonist from the class of fentanyl analogues which was found to be 30,000 times more potent than morphine in the rhesus monkey single dose suppression test. [1]
The weakest compounds such as benzylfentanyl are around the same potency as codeine (i.e. approximately 1/10th the potency of morphine), while the strongest compounds such as carfentanil and ohmefentanil can be over 10,000x more potent than morphine, meaning there is a 100,000-fold variation in potency between the strongest and weakest fentanyl ...
Fentanyl is a synthetic opioid in the phenylpiperidine family, which includes sufentanil, alfentanil, remifentanil, and carfentanil. [119] [120] Some fentanyl analogues, such as carfentanil, are up to 10,000 times stronger than morphine. [121]
Ohmefentanyl (also known as β-hydroxy-3-methylfentanyl, OMF and RTI-4614-4) [1] is an extremely potent opioid analgesic drug which selectively binds to the μ-opioid receptor.
N-Methylnorcarfentanil (R-32395) is an opioid analgesic drug related to the highly potent animal tranquilizer carfentanil, but several thousand times weaker, being only slightly stronger than morphine.
