Celecoxib is the active ingredient of Celebrex.
General Information
Celecoxib is prescribed to relieve pain and inflammation in patients with various types of arthritis. It is also used to treat pain after some types of dental surgery, and menstrual pain.
Because it has a more selective action, celecoxib has a lower risk of causing stomach irritation and bleeding. It should however be prescribed with caution to anyone with heart disease.
Celecoxib should not be taken by anyone who is allergic to sulphonamides or anyone who has asthma.
How does celecoxib work?
Celecoxib is a selective anti-inflammatory, meaning that it blocks the enzyme cyclooxygenase-2 (COX-2) responsible for prostaglandin (chemicals that play a role in pain and inflammation) synthesis without affecting the enzyme COX-1, involved in the production of prostaglandins that protects the lining of the stomach against stomach ulcers.
