Information about Celecoxib

Celecoxib is a nonsteroidal antiinflammatory drug (NSAID) with selectively for inhibition of cycloxgenase-2 (Cox-2), which is widely used in the therapy of arthritis. 

Liver safety of Celecoxib

Celecoxib has been linked to rare instances of idiosyncratic drug induced liver disease.  

Mechanism of action of Celecoxib

Celecoxib (sel" e kox' ib) is a commonly used NSAID with relative Cox-2 specificity.  Like other NSAIDs, celecoxib acts by inhibition of prostaglandin synthesis and thereby decreasing the mediators of inflammation, fever and pain.  The specificity for Cox-2 is believed to make celecoxib less likely to cause gastrointestinal mucosal injury compared to standard NSAIDs that inhibit both Cox-1 and Cox-2 enzymes.  Celecoxib is indicated for therapy of chronic arthritis due to osteoarthritis, rheumatoid arthritis, juvenile rheumatoid arthritis and ankylosing spondylitis.  It is also approved for use in acute pain from musculoskeletal conditions and trauma and for primary dysmenorrheal.  Because of the role of the Cox-2 enzyme system in the growth of adenomatous polyps, celecoxib has also been used to prevent adenomatous polyps formation. 

FDA approval information for Celecoxib

Celecoxib was first approved for use in the United States in 2000 and became the only Cox-2 specific NSAID available when rofecoxib was withdrawn in 2006 because of increased rate of cardiovascular events associated with its long term use. 

Dosage and administration for Celecoxib

Celecoxib is available by prescription as capsules of 50, 100, 200 and 400 mg under the commercial name Celebrex and is usually given in several week courses or long term.  The recommended dose varies by indication, the usual adult dose in arthritis being 100 to 200 mg twice daily.
