A study showed that arthritis patients treated with COX-2 inhibitors become more prone to stomach ulcers and internal bleeding if they do not take prescribed gastroprotective agents to counter irritation in the stomach and esophagus, which is a side effect of arthritis drugs. The findings contradict another trial showing the same risk for COX-2 inhibitor recipients regardless of whether they follow treatment with GPAs. WebMD/BMJ Group (4/17)
