Any medication given to relieve pain Narcotic analgesics include morphine, codeine, hydrocodone and oxycodone
An analgesic drug reduces the effect of pain. = painkilling. a drug that reduces pain = painkiller. Drug that relieves pain without blocking nerve impulse conduction or markedly altering sensory function (see nervous system). Two classes are defined by the type of pain-relieving action. Opioids (opiates and synthetic narcotics; see opium) act on brain receptors to inhibit pain impulses. They may be used for short-or long-term pain relief, usually by prescription, but carry a risk of drug addiction. Nonopioids, used mostly for short-term relief and modest pain, are available without prescription. They include NSAIDs (including aspirin and ibuprofen) and acetaminophen; all act by inhibiting synthesis of prostaglandins, molecules involved in the peripheral perception of pain
