The sulindac derivatives are synthesized by refluxing sulindac hydrazide with appropriately substituted benzaldehydes in the presence of ethanol and catalytic amounts of glacial acetic acid. The sulindac derivatives may be used as active ingredients in pharmaceutical compositions for the treatment of inflammation or inflammatory diseases. The sulindac derivatives may also be used as analgesic and/or gastric sparing agents.
