Rezost

Uses

This is primarily used for conditions like Osteoarthritis, Rheumatoid arthritis, Bone & Joint injuries.

Rezost is also used to associated treatment for these conditions: Osteoarthritis in the Hip Joint, Osteoarthritis of the Knee

How Rezost works

Diacerein's active metabolite rhein 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 . 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 .

Dosage

Rezost dosage

Adult & Children above 12 years: One tablet (Diacerein50 mg & Glucosamine Sulphate750 mg) twice daily for 4-12 weeks, taken with food.

Creatinine Clearance(CrCl) < 30 ml/min: The dose of Diacerein to be reduced.

Toxicity

Rhein Rhein has an oral LD50 of >5000mg/kg in mice. This is equivalent to a diacerein dose of >6476mg/kg.

Precaution

Caution should be practiced when administering Glucosamine + Diacerein in those patients who are allergic to Glucosamine and/or Diacerein or to shellfish (e.g., shrimp, crab); who have diabetes, asthma, alcohol dependence or liver disease. Before taking Glucosamine + Diacerein complete blood count, liver function and urinalysis should be monitored regularly.

Interaction

But decreased absorption of Diacerein with aluminium and/ or magnesium hydroxide antacids. Increased risk of diarrhea with laxatives, antibiotics.
