Nonsteroidal anti-inflammatory drugs (usually abbreviated to NSAIDs /ˈɛnsɛd/ EN-sed), also called nonsteroidal anti-inflammatory agents/analgesics (NSAIAs) or nonsteroidal anti-inflammatory medicines (NSAIMs), are a drug class that groups together drugs that provide analgesic (pain-killing) and antipyretic (fever-reducing) effects, and, in higher doses, anti-inflammatory effects.
