ABSTRACT

Aim: To evaluate the anti-inflammatory effect of antiplatelet agent, clopidogrel, in experimentally induced inflammatory bowel disease (IBD). Materials and Methods: TNBS induced Crohn's disease model and oxazolone induced ulcerative colitis model were used to evaluate the role of clopidogrel in IBD. Spargue Dawley female and Wistar male rats were used respectively. The colitis was induced by a single intra-colonic application of TNBS (0.25 ml, 120 mg/ml in 50% ethanol) and oxazolone (450 μl 5% oxazolone in 50% ethanol). Rats were divided into four groups (n=6) in each model namely normal control, sham control, test and standard group. Drug treatment was carried out for 21 days. After 21 days, animals were sacrificed and evaluated for weight change, colon mucosal damage index (CMDI), disease activity Index (DAI) and myeloperoxidase (MPO) activity. Results: Results showed that clopidogrel provided significant protection against mucosal damage in both the models of IBD. It significantly reduced (P<0.05) the decrease in body weight and CMDI, DAI and MPO scores. Conclusion: The results indicate that clopidogrel may be effective in treatment of Crohn's disease and ulcerative colitis. Platelet inhibition may be one of the mechanism for effectiveness of clopidogrel in the treatment of IBD.
