Acute, subacute and chronic toxicity of oxepinac.
The acute, subacute and chronic toxicity of 6,11-dihydro-11-oxodibenz[b,e]oxepin-3-acetic acid (oxepinac) was investigated in several animal species. The LD50 value was lower in rats than in rabbits, mice and dogs. The major cause of death was perforative ulcer in the gastrointestinal tract. Long-term study in rats revealed that oxepinac produced no hematological, blood chemical and pathological changes except for minor anemia and fatal ulcer formation occurring predominantly in females. Oxepinac proved to be less toxic than indometacin in chronic toxicity in rats.
