Parecoxib is primarily used in medical settings for the management of acute pain, particularly after surgical procedures. It is administered as an injectable solution, making it suitable for patients who cannot take oral medications immediately post-surgery. Its anti-inflammatory and analgesic properties help reduce pain and inflammation effectively, providing relief during the critical recovery period. Parecoxib is often preferred for its selective inhibition of COX-2 enzymes, which minimizes gastrointestinal side effects compared to non-selective NSAIDs. It is commonly used in orthopedic, abdominal, and dental surgeries to enhance patient comfort and improve recovery outcomes. However, its use is typically short-term due to potential cardiovascular risks associated with prolonged use of COX-2 inhibitors.
