Coenzyme Q10 (Co-Q10) is a vitamin-like supplement which appears to be safe, with minimal side effects and low drug interaction potential. Co-Q10 is used in the treatment of a variety of disorders related primarily to suboptimal cellular energy metabolism and oxidative injury. Studies supporting the efficacy of Co-Q10 appear most promising for a variety of diseases, including ulcerative colitis (UC). The present investigation aims to elucidate the possible protective effects of Co-Q10 against UC, as induced by the administration of iodoacetamide to adult male albino rats. In our study, Co-Q10 showed potent anti-oxidant and anti-inflammatory activities through a significant increase in catalase activity and glutathione content. In addition, it significantly decreased myeloperoxidase activity, malondialdehyde content and nitrate/nitrite production. These results suggest that Co-Q10 protects against UC in rats via anti-oxidant and anti-inflammatory potentials, and therefore seems promising for use in further clinical trials.
