“However the co-administration of vitamin E with celecoxib caused a significant increase in the antinociceptive effect which was similar to indomethacin, as a standard anti-inflammatory drug.”
“However, in tail-flick … ineffective doses of vitamin E (200 … celecoxib (10 and 30 mg/kg) increased %MPE and AUC compared to vehicle but not compared to celecoxib or vitamin … E and celecoxib showed a dose related antinociceptive effect in inflammatory but not in thermal model of acute pain.”
“The combination of vitamin E (100 or 200 mg/kg) with celecoxib (3 or 10 mg/kg) decreased pain scores compared to vehicle in both phases of formalin test, while in chronic phase (II) the pain scores of combination groups were also decreased compared to vitamin E and celecoxib.”
