Diacerein's active metabolite rhein [DB13174] 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. The anti-inflammatory action of rhein reduces the level of interleukin-1beta activity which plays a large role in reduction of extracellular matrix production, MMP activity, and continued inflammation. Rhein reduces abnormal osteoblast synthetic activity through an unknown mechanism.

Bioavailability of 50-60%. Entirely converted to the active metabolite rhein [DB13174] before reaching systemic circulation.

37% excreted in urine and 53% in feces as estimated in rats.
