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.
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 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 ...
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.

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 ]
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.
3-Methylfentanyl (3-MF, mefentanyl) is an opioid analgesic that is an analog of fentanyl. 3-Methylfentanyl is one of the most potent opioids, estimated to be between 400 and 6000 times stronger than morphine, [1] depending on which isomer is used (with the cis isomers being the more potent ones).
