Antinociceptive Effect of Ondansetron in Albino Mice Using Acetic Acid Induced Writhing Model
Journal Title: Journal of Krishna Institute of Medical Sciences University - Year 2016, Vol 5, Issue 4
Abstract
Background: Pain is an unpleasant sensory and emotional experience. Pain is a protective mechanism. Pain occurs whenever any tissues are being damaged, and it causes the individual to react and to remove the pain stimulus. Aim and Objectives: To evaluate the antinociceptive effect of ondansetron in comparison with the standard diclofenac. Material and Methods: The antinociceptive effect was tested by using the acetic acid induced writhing model in Swiss Albino mice. Animals were divided into 4 groups of 6 animals each. Animals were received distilled water (control), diclofenac (standard), ondansetron 0.5mg/kg (test I) and ondansetron 1mg/kg (test II). After 30 minutes of drug administration, 0.1 ml of 1% acetic acid was injected. Mice were placed individually into glass beakers and five minutes were allowed to elapse. They were then observed for a period of ten minutes and the numbers of writhes were recorded in each animal. The results were expressed as mean ± SEM. One way ANOVA with post-test was used for statistical calculation. Results: The numbers of writhes were 1.33±0.494 for diclofenac; 6.33±1.872 and 9.33±1.706 for ondansetron 0.5 and 1mg/kg respectively. Conclusion: Ondansetron demonstrated statistical significant antinociceptive activity at both doses (0.5mg/kg and 1mg/kg) and statistically similar effect as diclofenac.
