Health Centres - Eccoxolac (etodolac)
How does it work?
Eccoxolac capsules contain the active ingredient etodolac, which is a type of medicine called a non-steroidal anti-inflammatory drug (NSAID). NSAIDs are used to relieve pain and inflammation. (NB. Etodolac is also available without a brand name, ie as the generic medicine.)
Etodolac works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced by the body in response to injury and certain diseases and conditions, and cause pain, swelling and inflammation. Etodolac blocks the production of these prostaglandins and is therefore effective at reducing inflammation and pain.
Cyclo-oxygenase does not only produce prostaglandins that cause inflammation. It also produces prostaglandins that have useful roles in the body. There are two different forms of cyclo-oxygenase, COX-1 and COX-2. COX-2 is the form that (among other things) produces prostaglandins that cause inflammation. COX-1 does not produce inflammatory prostaglandins, but does produce others that have useful effects, including some that are involved in maintaining a healthy stomach and intestinal lining.
Traditional NSAIDs, such as ibuprofen or diclofenac, block the action of both COX-1 and COX-2 and this is why they can sometimes cause side effects such as stomach irritation and peptic ulcers. Etodolac belongs to a new generation of NSAIDs that selectively block the action of COX-2. This means that it stops the production of inflammatory prostaglandins, without stopping the production of prostaglandins that protect the stomach and intestines. It therefore reduces pain and inflammation, but is less likely than traditional NSAIDs to cause side effects on the stomach and intestines (although such side effects are still possible).
Etodolac is used to relieve the pain of osteoarthritis and rheumatoid arthritis, which is a result of inflammation in the joints.
