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.
β-Hydroxyfentanyl is an opioid analgesic that is an analogue of fentanyl.. β-Hydroxyfentanyl was sold briefly on the black market in the early 1980s, before the introduction of the Federal Analog Act which for the first time attempted to control entire families of drugs based on their structural similarity rather than scheduling each drug individually as they appeared.
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 many types of analgesic patches based on the main ingredients in the patches. These include patches containing counterirritants, which are used to treat mild to moderate pain, and patches containing opioids such as buprenorphine and fentanyl, used to relieve moderate to severe pain. Fentanyl is often used for opioid-tolerant patients.
3-Methylbutyrfentanyl (3-MBF) is an opioid analgesic that is an analog of butyrfentanyl. [2] [3] [4] [5]Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening.
β-Hydroxythiofentanyl (beta-hydroxythiofentanyl) is an opioid analgesic that is an analog of fentanyl and thiofentanyl.. β-Hydroxythiofentanyl was sold briefly on the black market from around 1985, [1] before the introduction of the Federal Analog Act in 1986 which for the first time attempted to control entire families of drugs based on their structural similarity rather than scheduling ...
