Ibuprofen, chemically named isobutylphenyl propionic acid, belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs). This medication demonstrates effective anti-inflammatory, pain-relieving, and fever-reducing properties while exhibiting minimal side effects. Its global acceptance has made it one of the most widely sold over-the-counter medications worldwide. Alongside aspirin and paracetamol, ibuprofen is recognized as one of the three fundamental antipyretic and analgesic products.
In China, this drug is primarily utilized for pain management and rheumatism treatment, with comparatively limited application for treating colds and reducing fever - a usage pattern that significantly trails behind that of paracetamol and aspirin.
