ABSTRACT
The present study was aimed to assess the combined effects of cyclooxygenase and 5-lipoxygenase (COX/5-LOX) inhibitors in different animal models of nociception. Naproxen, nimesulide and rofecoxib are well-established antinociceptive agents acting via COX inhibition. AKBA (acetyl-keto-beta-boswellic acid) is a 5-LOX inhibitor. AKBA (50-200 mg/kg) produced a dose dependent and significant antinociceptive effect in different animal models of nociception. Based on the earlier reports from our laboratory, sub effective doses of all the three COX Inhibitors were selected and they were administered (naproxen, 5 mg/kg; nimesulide, 1 mg/kg; and rofecoxib, 1 mg/kg) with AKBA (100 mg/kg). This produced a more significant antinociceptive effect as compared to per se effect observed in all the three models of nociception. However, the effect of combination of nimesulide with AKBA was more pronounced as compared to naproxen and rofecoxib and their combination with AKBA. The present finding provided an evidence for the potentiation of antinociceptive effect of NSAIDs with AKBA. Such a combination may help to reduce the therapeutic doses of conventional NSAIDs and also reduce side effects (gastric, cardiac and renal) that are popularly associated with the NSAIDs.
