Oral naproxen is effective in reducing nociceptive behavior in 4 day CFA-injected rats. Naproxen reduced A) mechanical thresholds and B) paw withdrawal latencies taken 2 hr post dose. n = 6-16 rats per group. For this and other figures, data is presented as mean +/- s.e.m. **p < 0.01 and ***p < 0.001, significant differences from vehicle (saline) - dosed rats.
