Dfriz

Uses

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

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

How Dfriz 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

Dfriz 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.

Side Effects

Diarrhea, constipation, epigastric pain, heart burn, nausea, vomiting, headache, skin rashes, drowsiness, intense yellow coloring of urine.

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

There have been no reports of significant drug interactions of Glucosamine with antibiotics/ antidepressants/ antihypertensives/ nitrates/ antiarrythmics/ anxiolytic/ hypoglycemic agents/ antisecretives. But decreased absorption of Diacerein with aluminium and/ or magnesium hydroxide antacids. Increased risk of diarrhea with laxatives, antibiotics. Avoid co-administration with fibres and phytic acids.
