Brief Summary
Gastrointestinal bleeding is a severe adverse effect occurring in subjects secondary to the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The enzyme CYP2C9 is responsible for the elimination of several NSAIDs. This protein is inactive in 12% of the subjects because of genetic mutations. We hypothesized that individuals carrying such mutations should be at higher risk of gastrointestinal bleeding since they display decreased NSAIDs elimination.
