Diacerein is a prodrug which is metabolized to rhein. It is currently approved in France for the treatment of osteoarthritis although the use of diacerein is restricted due to the side effects including severe diarrhea. Diacerein is under investigation for the treatment of Insulin Resistance, Diabetes Mellitus (Type 2), and Diabetes-Related Complications.
Diacerein also is known as diacetylrhein, is a slow-acting medicine of the class anthraquinone used to treat joint diseases such as osteoarthritis (swelling and pain in the joints). It works by inhibiting interleukin-1 beta. An updated 2014 Cochrane review found diacerein had a small beneficial effect on pain. It is used to relieve pain and swelling associated with Osteoarthritis. This medicine is slow acting and is used as a long-term treatment option for osteoarthritis.
Mechanism of action of Diacerein
Diacerein’s active metabolite rhein reduces cartilage destruction by decreasing expression of matrix metalloproteinase (MMP)-1 and -3 as well as upregulating tissue inhibitor of matrix metalloproteinases which serve to reduce the activity of several MMPs.This compound belongs to the class of organic compounds known as anthracene carboxylic acids. These are organic compounds containing a carboxylic acid group attached to an anthracene ring system. The anti-inflammatory action of rhein reduces the level of interleukin-1beta activity which plays a large role in the reduction of extracellular matrix production, MMP activity, and continued inflammation. Rhein reduces abnormal osteoblast synthetic activity through an unknown mechanism
