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]
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.
Benzoylfentanyl, also known as phenylfentanyl, is an opioid analgesic that is an analog of fentanyl and has been sold as a designer drug. [ 1 ] [ 2 ] In the United States, benzoylfentanyl was first identified in Drug Enforcement Administration drug seizures in 2018.
The UK Department of Health (now the DHSC) agreed to fund the BNFC, as it does the BNF, to ensure that NHS clinicians can have up-to-date information in their pockets. The first edition was published in 2005, with George Rylance [ 7 ] chairing the Paediatric Formulary Committee and Dinesh Mehta as the first executive editor.
The tables below contain a sample list of benzodiazepines and benzodiazepine analogs that are commonly prescribed, with their basic pharmacological characteristics, such as half-life and equivalent doses to other benzodiazepines, also listed, along with their trade names and primary uses.
Fentanyl is a highly potent synthetic piperidine opioid primarily used as an analgesic. It is 30 to 50 times more potent than heroin and 50 to 100 times more potent ...
Benzylfentanyl (R-4129) is a fentanyl analog. [1] It was temporarily placed in the US Schedule I by emergency scheduling in 1985 due to concerns about its potential for abuse as a designer drug, but this placement was allowed to expire and benzylfentanyl was formally removed from controlled substance listing in 2010, after the DEA's testing determined it to be "essentially inactive" as an ...
Acetylfentanyl (acetyl fentanyl) is an opioid analgesic drug that is an analog of fentanyl. [4] Studies have estimated acetylfentanyl to be 15 times more potent than morphine , [ 5 ] [ 6 ] which would mean that despite being somewhat weaker than fentanyl, it is nevertheless still several times stronger than pure heroin .
