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]
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management.Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and ...
"Pain ladder", or analgesic ladder, was created by the World Health Organization (WHO) as a guideline for the use of drugs in the management of pain. Originally published in 1986 for the management of cancer pain , it is now widely used by medical professionals for the management of all types of pain .
In pharmacology, the term ceiling effect refers to the property of increasing doses of a given medication to have progressively smaller incremental effect (an example of diminishing returns). Mixed agonist-antagonist opioids , such as nalbuphine , serve as a classic example of the ceiling effect; increasing the dose of a narcotic frequently ...
In clinical trials, the MOR is the main target of opioid ligand binding. While binding of the opioid to the MOR typically causes analgesia, there can be instances where hyperalgesia occurs. [20] It has been speculated that the opposite analgesic and hyperanalgesic effects are due to different isoforms of the receptor.
Pain management is an aspect of medicine and health care involving relief of pain (pain relief, analgesia, pain control) in various dimensions, from acute and simple to chronic and challenging.
An analgesic adjuvant is a medication that is typically used for indications other than pain control but provides control of pain in some painful diseases. This is often part of multimodal analgesia , where one of the intentions is to minimize the need for opioids.
Analgesics are a class of biochemicals that cause hypoalgesia. Analgesics can act on both the peripheral and central nervous systems to decrease pain. Certain analgesics also work to decrease the source of the pain by working to decrease swelling and inflammation, as in the case of NSAIDs .
