Used primarily as a selective COX-2 inhibitor, it provides anti-inflammatory, analgesic, and antipyretic effects. Commonly prescribed for acute pain, osteoarthritis, and primary dysmenorrhea due to its rapid onset of action. Also utilized in postoperative pain management and dental pain. Its selectivity for COX-2 over COX-1 reduces gastrointestinal side effects compared to non-selective NSAIDs. However, due to hepatotoxicity risks, its use is restricted or withdrawn in several countries.
