Celecoxib

Who is Celecoxib for ?

Celecoxib is used to relieve the pain, tenderness, inflammation (swelling), and stiffness caused by arthritis. this medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Celecoxib is a COX-2 inhibitor that works specifically on an enzyme called COX-2. Scientists discovered two COX enzymes, called COX-1 and COX-2. The COX-1 enzyme plays a role in stomach and kidney damage. The COX-2 enzyme mainly plays a role in inflammation and pain. While traditional non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen inhibit the COX-2 enzyme and help to relieve pain and inflammation, they also inhibit the COX-1 enzyme and thus can cause gastrointestinal side effects like ulcers. COX-2 inhibitors like celecoxib, have specific action on the COX-2 enzyme to decrease pain and inflammation, but have less action on the COX-1 enzyme and thus are associated with a lower occurrence of gastrointestinal side effects.
