What is Rantudil® (acemetacin) used for?
Rantudil® is commonly used for treating:
- Postoperative pain
- Pain and inflammation associated with musculoskeletal
- Joint disorders
- Ankylosing spondylitis
- Rheumatic conditions
- Pain after surgical operations
Acemetacin works by blocking the effect of chemicals called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals in the body, called prostaglandins. Some prostaglandins are produced at sites of injury or damage, and cause pain and inflammation. By blocking the effect of COX enzymes, fewer prostaglandins are produced, which means pain and inflammation are eased.
