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
