analgesic

n. a drug or other agent that alleviates pain. Analgesic drugs usually are classed as opioid (narcotic) or nonopioid (nonnarcotic), depending on their chemical composition and potential for physical dependence. Opioid analgesics are generally the most effective in relieving pain. The most widely used of the less potent nonopioid analgesics are the NSAIDs (nonsteroidal anti-inflammatory drugs)—most notably aspirin—and acetaminophen.
