Hair analysis in the detection of long-term use of non-steroidal anti-inflammatory drugs and its relation to gastrointestinal hemorrhage: an examination of 268 hair and blood samples from autopsy cases.

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used as analgesics and antipyretics in Western countries. Gastrointestinal (GI) disorders are common side effects of NSAIDs and other drugs. This study investigated the correlation between chronic use of these substances and GI lesions by analyzing postmortem blood and hair samples from autopsy cases.
