An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]

Butyrfentanyl or butyrylfentanyl is a potent short-acting synthetic opioid analgesic drug.It is an analog of fentanyl with around one quarter of its potency. One of the first mentions of this drug can be found in document written by The College on Problem of Drug Dependence, where it is mentioned as N-butyramide fentanyl analog. [1]
The synthesis of fentanyl and its analogues are illustrated in this skeletal diagram. Part II. The modifications covered in this diagram have to do with carbon skeleton modifications of the original fentanyl molecular structure. These are organized into methyl acetate additions, which are most known for the fentanyl -> carfentanil conversion.
4-Phenylfentanyl is an opioid analgesic that is a derivative of fentanyl.It was developed during the course of research that ultimately resulted in super-potent opioid derivatives such as carfentanil, though it is a substantially less potent analogue. 4-Phenylfentanyl is around eight times the potency of fentanyl in analgesic tests on animals, but more complex 4-heteroaryl derivatives such as ...
There are no clinical guidelines outlining the use and implementation of opioid rotation. However, this strategy is commonly used for these various situations: pain not controlled by current opioid, pain controlled but in the presence of intolerable adverse events, pain not controlled despite rapid increase in opioid dose, switching to utilize different alternative routes of administration, or ...
The nurse, a 54-year-old woman from Janesville, replaced fentanyl, a powerful synthetic opioid, with saline, a mixture of salt and water, while working at a local hospital in 2021, according to a ...
Norfentanyl occurs primarily as a metabolite of its parent drug, fentanyl. However, it can also be used to synthesize fentanyl itself. However, it can also be used to synthesize fentanyl itself. See also
