Variability in Response to Non-steroidal Anti-inflammatory Drugs
Summary
This research study will evaluate inter-individual variability in the response to the non-steroidal anti-inflammatory drugs (NSAIDs), celecoxib and naproxen, among healthy adults. It will also investigate what factors, like age, sex, or genetic background, cause this variability.
