Nonsteroidal anti-inflammatory drug

Nonsteroidal anti-imflammatory drugs, or NSAIDs, are a class of drugs which provide both analgesic (pain-killing) and antipyretic (fever-reducing) effects, and anti-inflammatory effects in higher doses. They range from mild to strong pain relief.

Commonly used NSAIDs include aspirin, ibuprofen, naproxen, diclofenac, celecoxib, meloxicam, mefenamic acid, and nabumetone.
