  • Miscellaneous

    • Chemical Class:

      A monocarboxylic acid that is propionic acid substituted at position 2 by a 2-(4-chlorophenyl)-1,3-benzoxazol-5-yl group (the <stereo>S</stereo>-enantiomer). Although it was shown to be effective in t reatment of rheumatoid arthritis and osteoarthritis, the clinical use of flunoxaprofen was discontinued due to possible hepatotoxic side-effects.
