Indomethacin Capsules are oral non-steroidal anti-inflammatory drugs (NSAIDs) containing indomethacin as the active ingredient. They work by inhibiting the synthesis of prostaglandins, thereby exerting strong anti-inflammatory, analgesic, and antipyretic effects. These capsules are widely used in the treatment of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gouty arthritis, and other inflammatory joint diseases. They can also relieve acute pain caused by soft tissue injuries, postoperative pain, and dysmenorrhea. The capsule formulation ensures accurate dosage, stable drug release, and convenient oral administration, making it suitable for long-term or short-term use as prescribed by doctors.
