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]
Replacing the methyl ester on the long chain with a tert-butyl ester makes the remifentanil analogue 150.000 times more potent than morphine and 210 times more potent than remifentanil itself, which makes it one of the most potent fentanyl analogues known. The tert-butyl group also makes it more resistant to hydrolysis and extends its half life ...
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.
Belbuca, Buprenex, Butrans, Subutex, Probuohine (buprenorphine) - an opioid medicine used to treat moderate to severe pain, and in some formulations to treat opioid use disorder; Belsomra – used to treat insomnia
