ORICOX 90 MG is a medication containing etoricoxib, a non-steroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2). 1 It is primarily used to relieve pain and inflammation associated with various conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and 2 gouty arthritis. Additionally, it can be prescribed for short-term relief of moderate pain following dental surgery. 3 By blocking COX-2, etoricoxib reduces the production of prostaglandins, which are chemicals in the body that contribute to pain, swelling, and inflammation.
