Ibuprofen (from the earlier nomenclature iso-butyl-propanoic-phenolic acid) is a non-steroidal anti-inflammatory drug (NSAID) originally marketed as Nurofen and since then under various other trademarks (See tradenames section). It is used for relief of symptoms of arthritis, primary dysmenorrhea, fever, and as an analgesic, especially where there is an inflammatory component. Ibuprofen is known to have an antiplatelet (blood-thinning) effect, though it is relatively mild and short-lived when compared to to or other more well-known antiplatelet drugs.
