In this study, celecoxib, at dosages greater than those indicated clinically, was associated with a lower incidence of symptomatic ulcers and ulcer complications combined, as well as other clinically important toxic effects, compared with NSAIDs at standard dosages. The decrease in upper GI toxicity was strongest among patients not taking aspirin concomitantly. JAMA. 2000;284:1247-1255

In older patients with rheumatoid arthritis, misoprostol reduced serious NSAID-induced upper gastrointestinal complications by 40% compared with placebo.

The most common agents of infection transmitted by endoscopy are Salmonella, Pseudomonas, and Mycobacterium species. To prevent endoscopic transmission of infections, recommended disinfection guidelines must be followed, the effectiveness of automatic washers must be carefully monitored, and improvements in endoscope design are needed to facilitate effective cleaning and disinfection.

The incidence of UGI ulcer complications associated with celecoxib was 8-fold lower than with nonspecific NSAIDs. The incidence of ulcer complications observed in celecoxib-treated patients was similar to that in patients receiving placebo in the RCTs, and to that in non-NSAID users reported in the literature.
