Etoricoxib is the active ingredient of Arcoxia.
Etoricoxib is prescribed to relieve pain and inflammation in patients with various types of arthritis. It is also used to treat acute gout attacks.
Because it has a more selective action, etoricoxib has a lower risk of causing stomach irritation and bleeding compared to other non-steroidal anti-inflammatory drugs. It should however be prescribed with caution to anyone with heart disease.
Your doctor may need to follow your progress while you are taking this medication, especially if you are elderly or have heart, liver or kidney disease. It is important that you use the lowest dose that controls your pain and you should not take etoricoxib for longer than necessary. This is because the risk of heart attacks and strokes might increase after prolonged treatment, especially with high doses.
Etoricoxib can also increase your blood pressure, particularly if taken in high doses. This could increase the risk of heart attack or stroke even further. Your doctor should check your blood pressure from time to time, to make sure that it is safe to continue treatment.
Etoricoxib should not be taken if you are allergic to sulphonamides, or if you have asthma.
How does etoricoxib work?
Etoricoxib 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 protect the lining of the stomach against stomach ulcers.
