Acute pancreatitis(AP)is an inflammatory condition of the pancreas following the activationt of pancreatic enzymes induced by a variety of factors,with or without other organ dysfunction.The production and release of inflammatory factors is generally considered as a key link during pathogenesis.Non-steroidal anti-inflammatory drugs(NSAIDs)are the most commonly applied agents for inflammatory diseases.Many studies have proved that indomethacin can reduce the risk of pancreatitis after endoscopic retrograde cholangiopancreatography;however,few high-quality evidences have demonstrated the roles of NSAIDs in treating,rather than preventing AP.Most animal experiments have shown that NSAIDs can protect organs,although the currently available findings remained inconsistent.Randomized controlled trials with large sample sizes are warranted to elucidate the roles of NSAIDs in treating AP.
