Indomethacin
A nonsteroidal anti-inflammatory drug (NSAID) with strong analgesic and anti-inflammatory effects. It is used to treat musculoskeletal conditions such as arthritis, low back pain, and gout. It works by inhibiting COX enzymes, reducing the production of prostaglandins that cause pain and inflammation. Its use may be associated with side effects, especially in the gastrointestinal system, and requires medical supervision.
