OriginDerived from salicylic acid, a beta hydroxy acid compound synthesized from petroleum-based or coal tar feedstock. Produced through neutralization of salicylic acid with sodium hydroxide or sodium carbonate.
A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)
