BACKGROUNDS: Gastrointestinal (GI) toxicity is an undesirable effect of nonsteroidal anti-inflammatory drugs (NSAIDs). We conducted a multicenter study in Japan to clarify the GI risk grade in patients with NSAID-induced GI bleeding. METHODS: Patients with emergent endoscopic hemostasis by nonvariceal bleeding were registered from 36 hospitals in Hiroshima. In cases with NSAID use, the GI risk grade (low, moderate, or high) was evaluated, and concomitant drugs were investigated. We asked 79 gastroenterologists and 234 orthopedists what concomitant drugs they would prescribe to 3 simulated patients. RESULTS: A total of 1,350 patients were registered. NSAIDs were used in 278 cases (21%). Concerning the risk grade in each patient, the largest group was the moderate-risk group (203 patients; 73%), while the high-risk group comprised 10% of all NSAID users with bleeding. A proton pump inhibitor (PPI) or misoprostol was administrated to only 20 patients (7%). A small number of the gastroenterologists and orthopedists who responded to the questionnaire would prescribe PPI or misoprostol to simulated patients with short-term loxoprofen use. CONCLUSIONS: In NSAID users with GI bleeding, the moderate-risk group was the largest group for GI toxicity in Japan. In these cases, PPI or misoprostol was not commonly medicated in clinical practice.
