aspirin 音标拼音: ['æsprɪn] n. 阿斯匹林 阿斯匹林 aspirin n 1: the acetylated derivative of salicylic acid; used as an analgesic anti- inflammatory drug ( trade names Bayer, Empirin, and St. Joseph) usually taken in tablet form; used as an antipyretic; slows clotting of the blood by poisoning platelets [ synonym: { aspirin}, { acetylsalicylic acid}, { Bayer}, { Empirin}, { St. Joseph}] Aspirin \ As" pi* rin\, n. ( Pharm.) A white crystalline compound, acetyl salicylic acid ({ CH3. CO. O. C6H4. CO. OH}) widely used as a drug for relief of pain and alleviation of fever. It has analgesic, antipyretic, and antiinflammatory properties, and is one of a class of agents called non- steroidal antiinflammatory drugs ( NSAIDs). The name was originally a trade name, but has become the preferred name for the substance. It is actually a prodrug, liberating salicylic acid, the ultimate pharmacologically active agent, in the intestines. It is more effective when taken orally than is salicylic acid, because it dissolves more readily. Syn: 2-( acetyloxy) benzoic acid [ Webster 1913 Suppl. PJC] |
