Question: do nsaids cause gastric or duodenal ulcers?
Answer: By blocking the Cox-1 enzyme and disrupting the production of prostaglandins in the stomach, NSAIDs can cause ulcers and bleeding. Some NSAIDs have less effect on prostaglandins in the stomach than others, and, therefore, may have a lower risk of causing ulcers, but the increased risk of ulcers still exists.
