1. What Preservex is and what it is used for

Preservex belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). They have anti-inflammatory and painkiller properties causing a lowering of swelling, redness (inflammation) and pain. The medicine/active ingredient of Preservex is aceclofenac.

Preservex works by blocking the production of hormone-like substances called prostaglandins.

Prostaglandins have many functions in the body including an important role in both the way the body responds to inflammation and also the reabsorption of calcium in some diseases of the bone.

Preservex is used to relieve pain and reduce redness and swelling (inflammation) in patients suffering from:

  • Osteoarthritis - inflammation of the joints. This is a common condition in patients over the age of 50 and causes damage to the tissues and bones in the joints.
  • Rheumatoid arthritis - long term inflammation of the joints caused by the body’s own immune system (autoimmune response).
  • Ankylosing spondylitis - inflammation of the spine/backbone which can lead to the joints fusing together.
