Abstract

Subjects and Methods: This is a comparative study of analgesic efficacy between aspirin, diclofenac and ketorolac. 40 albino rats were taken and divided into 4 equal groups. Group A, B, C and D treated with normal saline, Aspirin, diclofenac and ketorolac respectively. Results: Significant increase in reaction time was observed with aspirin, diclofenac and ketorolac (p<0.001) using hotplate analgesia meter. Increase in tail flick latency was also found with all three drugs. Ketorolac produces 6.7 second increase in tail flick latency. Conclusion: NSAIDs are the first line of management in acute and chronic pain. Ketorolac is more effective than other nonsteroidal anti-inflammatory drugs.
