Celecoxib is a selective COX-2 inhibitor nonsteroidal anti-inflammatory drug (NSAID) used for the treatment of pain and inflammation in conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, juvenile idiopathic arthritis, and acute pain. It is an approved prescription medication in many countries.
