"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 .
Treatment approaches to chronic pain include pharmacological measures, such as analgesics (pain killer drugs), antidepressants, and anticonvulsants; interventional procedures, physical therapy, physical exercise, application of ice or heat; and psychological measures, such as biofeedback and cognitive behavioral therapy.

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 ...
"Strength" is defined as analgesic potency relative to oral morphine. Tolerance, sensitization, cross-tolerance, metabolism, and hyperalgesia may be complex factors in some individuals. Interactions with other drugs, food and drink, and other factors may increase or decrease the effect of certain analgesics and alter their half-life.
In several major drug classification systems, these four types of classifications are organized into a hierarchy. [4] For example, fibrates are a chemical class of drugs (amphipathic carboxylic acids) that share the same mechanism of action ( PPAR agonist ), the same mode of action (reducing blood triglyceride levels), and are used to prevent ...
The core items are deemed to be the most cost-effective options for key health problems and are usable with little additional health care resources. [4] The complementary items either require additional infrastructure such as specially trained health care providers or diagnostic equipment or have a lower cost–benefit ratio . [ 4 ]
An elaborate and widely used classification system is the Anatomical Therapeutic Chemical Classification System (ATC system). The World Health Organization keeps a list of essential medicines. A sampling of classes of medicine includes: Antipyretics: reducing fever (pyrexia/pyresis) Analgesics: reducing pain (painkillers)
Conventional insulin therapy is characterized by: Insulin injections of a mixture of regular (or rapid) and intermediate acting insulin are performed two times a day, or to improve overnight glucose, mixed in the morning to cover breakfast and lunch, but with regular (or rapid) acting insulin alone for dinner and intermediate acting insulin at bedtime (instead of being mixed in at dinner).
