Tricyclic derivatives of substituted pyrrole acids, e.g., substituted 4,10-dihydro-10-oxo-1H-[1]benzoxepino[4,3-b]pyrrole-2-acetic acids or the 5-thia analogs thereof have been prepared via hydrolysis of a precursor or decarboxylation of a precursor-diacid. These tricyclic compounds are found to have high analgesic and anti-inflammatory activities but low ulcerogenic side effects.
