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.
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.
Fentanyl transdermal patches are sold under the brand name Duragesic or as generic equivalents. Fentanyl is an opioid with rapid onset of pain relief; it is often used to treat breakthrough pain. Fentanyl patches release fentanyl through the skin and may provide pain relief for up to 72 hours. [6]
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.
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 ...
Lofentanil or lofentanyl 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.
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.
