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 ...
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.
Opioids are effective analgesics in chronic malignant pain and modestly effective in nonmalignant pain management. [66] However, there are associated adverse effects, especially during the commencement or change in dose. When opioids are used for prolonged periods drug tolerance will occur.
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 .
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.
Placebo analgesia occurs when the administration of placebos leads to pain relief.Because placebos by definition lack active ingredients, the effect of placebo analgesia is considered to result from the patient's belief that they are receiving an analgesic drug or other medical intervention.
"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 .
