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. [2] [3] There are eight possible stereoisomers of ohmefentanyl.
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 ...
Lofentanil or lofentanyl is one of the most potent opioid analgesics known and is an analogue of fentanyl, which was developed in 1960. It is most similar to the highly potent opioid carfentanil (4-carbomethoxyfentanyl), only slightly more potent. Lofentanil can be described as 3-methylcarfentanil, or 3-methyl-4-carbomethoxyfentanyl.
The opioid receptor antagonist naloxone is used to reverse opioid overdose. [7] Extremely potent opioids such as carfentanil are approved only for veterinary use. [8] [9] [10] Opioids are also frequently used recreationally for their euphoric effects or to prevent withdrawal. [11]
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 which is a structural derivative.
A synthetic opioid approximately 100 times more potent than fentanyl has shown up in Sedgwick County, and public health officials don’t know where it’s coming from.
Many charts derive their data from studies conducted on opioid-naive patients. Patients with chronic (rather than acute) pain may respond to analgesia differently. Repeated administration of a medication is also different from single dosing, as many drugs have active metabolites that can build up in the body. [ 6 ]
