Imrecoxib is primarily used as a nonsteroidal anti-inflammatory drug (NSAID) to manage pain and inflammation associated with conditions like osteoarthritis. It works by selectively inhibiting cyclooxygenase-2 (COX-2), an enzyme responsible for inflammation and pain, while minimizing effects on COX-1, which helps reduce gastrointestinal side effects commonly seen with traditional NSAIDs. This makes it a suitable option for patients requiring long-term pain management with a lower risk of stomach-related complications. Additionally, it is being studied for its potential therapeutic effects in other inflammatory diseases and conditions, expanding its scope of application in clinical settings.
