N: 1. analgesic (adj.), “tending to remove pain,” 1848, from “analgesia” + “-ic”. Alternative form analgetic (from Greek analgetos “without pain”) is classically correct but less common.
analgesic (n): The noun meaning “an analgesic preparation, anything which removes pain” is recorded by 1860.
Frequent use in plural: analgesics.
2. A drug that relieves or reduces pain.
3. Analgesic, any drug that relieves pain selectively without blocking the conduction of nerve impulses, markedly altering sensory perception, or affecting consciousness. This selectivity is an important distinction between an analgesic and an anesthetic (anesthetic, also spelled anaesthetic, any agent that produces a local or general loss of sensation, including pain; anesthetics achieve this effect by acting on the brain or peripheral nervous system to suppress responses to sensory stimulation).
4. Analgesics may be classified into two types: anti-inflammatory drugs, which alleviate pain by reducing local inflammatory responses; and the opioids, which act on the brain. The opioid analgesics were once called narcotic drugs because they can induce sleep. The opioid analgesics can be used for either short-term or long-term relief of severe pain. In contrast, the anti-inflammatory compounds are used for short-term pain relief and for modest pain, such as that of headache, muscle strain, bruising, or arthritis.
