In the present study, we investigated the effects of nimesulide, indomethacin, naproxene, ibuprofen and diclofenac, at anti-inflammatory doses, on the rat gastric tissue (total number = 102). In addition, the effect of nimesulide at doses of 100, 300 and 500 mg kg-1 on indomethacin-induced and ethanol-induced damage (ulcer) was examined. The potency of nimesulide was compared with that of ranitidine (at 150 mg kg-1). Results indicated that nimesulide did not produce any gastric damage. Additionally, it has a therapeutic effect on indomethacin- and ethanol-induced gastric lesions. Ulcer areas were measured in the rats given nonsteroidal anti-inflammatory drugs (NSAIDs). Nimesulide (at doses of 100, 300 and 500 mg kg-1) and ranitidine (at a dose of 150 mg kg-1) treated completely indomethacin-induced ulcer. The mean ulcer area was 21.9 ± 8.9 mm2 in the indomethacin-given control group. Nimesulide and ranitidine reduced the ethanol-induced gastric ulcer. The ulcer area was 114.3 ± 10.3 mm2 in the ethanol-given group and it was 4.5 ± 4.8, 20.1 ± 1.66, 15.16 ± 4.05 mm2 for nimesulide (at doses of 100, 300 and 500 mg kg-1), respectively, and 64.16 ± 3.97 mm2 for ranitidine. © 2002 Elsevier Science Ltd.
