The gastroduodenal mucosa in dogs experimentally treated with nimesulide, monophenylbutazone and meloxicam was evaluated. There were four groups with eight dogs in each. Groups one, two and three were given nimesulide, monophenylbutazone and meloxicam, respectively, during 21 days and group four was used as control. All animals were evaluated by gastroduodenoscopy before the study and on the 10th and 21st days. The dogs did not show any clinical or laboratorial changes during the study. The endoscopic evaluation of gastroduodenal mucosa showed only low degree lesions. These anti-inflammatory drugs showed to be safe for the gastrointestinal tract in healthy dogs.
