Lofentanil HCL

Lofentanil HCL 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 HCL can be described as 3-methylcarfentanil, or 3-methyl-4-carbomethoxyfentanyl. While 3-methylfentanyl is considerably more potent than fentanyl itself, lofentanil is only slightly stronger than carfentanil. This suggests that substitution at both the 3 and 4 positions of the piperidine ring introduces steric hindrance which prevents μ-opioid affinityfrom increasing much further. As with other 3-substituted fentanyl derivatives such as ohmefentanyl, the stereoisomerismof Lofentanil HCL is very important, with some stereoisomers being much more potent than others.

Lofentanil is very similar to carfentanil in effects, but has a longer duration of action. This makes it unsuitable for most practical applications, with carfentanil being the preferred agent for tranquilizing large animals, and short-acting derivatives such as sufentanil or remifentanil being preferred for medical use in human surgical procedures. The long duration and high lipophilicity of Lofentanil HCL has been suggested as an advantage for certain types of analgesia, but the main application for lofentanil at the present time is research into opioid receptors.
