Medical Definition of NSAID

NSAID: Nonsteroidal anti-inflammatory drug, a medication that is commonly prescribed or purchased over the counter to treat the inflammation associated with conditions such as arthritis, tendonitis, and bursitis. Examples of NSAIDs include aspirin, indomethacin (brand name: Indocin), ibuprofen (brand name: Motrin), naproxen (brand name: Naprosyn), piroxicam (brand name: Feldene), and nabumetone (brand name: Relafen). People who take certain NSAIDs may have a higher risk of having a heart attack or a stroke than people who do not take these medications. This risk may be higher for people who take NSAIDs for a long time. Other major side effects of NSAIDs are gastrointestinal problems. Some 10 to 50 percent of patients are unable to tolerate NSAID treatment because of these side effects, which include abdominal pain, diarrhea, bloating, heartburn, and upset stomach.
