Background: Obviously, antibacterial agents are primarily directed against bacteria. However, because microorganisms can initiate an exaggerated inflammatory reaction, and as pathogens which persist in cryptic reservoirs (cells or granuloma tissue) can be the underlying cause of chronic inflammation, the hypothesis that antibacterials can down regulate inflammation. Methodology: Healthy adult mice weighing 20 – 30 g and aged 6-8 weeks, each group 6 mice were included. 1% carrageenan administered to produce inflammation. Grouping: Group 1: Normal saline 0.2 ml. i.p., Group 2: Diclofenac sodium 25mg/kg, Group 3 Ciprofloxacin 50 mg/kg, Group 4: Azithromycin 20mg/kg. Drugs were administered Intra Peritoneal. After 30 min of test drugs administration each group of mice were received subplantar administration of 0.05ml of saline (Control) or 0.05ml carrageenan (1%) for test groups 2 to 4. Paw volumes were measured by dipping in to the mercury plethysmograph at 30, 60, 120 and 180 minutes and results were tabulated. Results: Diclofenac, ciproflaoxin, Azithromycin inhibited paw edema in % at 30min 42.85, 28.55, 14.28, at 60min 75, 50, 25, at 120min 71.42, 42.85, 14.28, and at 180 min 50, 50, 25 respectively. Conclusion: Ciprofloxacin (50mg/kg) has exhibited consistent anti-inflammatory, but the anti-inflammatory activity of is less than that of Diclofenac sodium and Azithromycin also has exhibited anti-inflammatory activity, though much less when compared to Diclofenac sodium and Ciprofloxacin.
