Glucosamine: Glucosamine (2-amino-2-deoxy-alpha-D-glucose) is a natural amino sugar, produced by the body and found in certain foods. It is the most fundamental building block required for biosynthesis of glycosaminoglycans (GAGs) like Hyaluronic Acid, Keratan Sulfate and Chondroitin Sulfate. GAGs binds with protein and form proteoglycans, the essential building block of articular cartilage. When cartilage in a joint deteriorates, Osteoarthritis develops. It also helps to form ligaments, tendon, nails and various other connective tissues. When we take artificially synthesized Glucosamine Sulfate supplement, it increases Glucosamine level in the body, thus facilitates production and repair of cartilage. Glucosamine also activates chondrocytes in the cartilage which help produce GAGs and proteoglycans.

In humans, about 90 percent of glucosamine, administered as an oral dose of glucosamine sulfate, is absorbed from the digestive tract. Predominantly metabolized by liver & excreted through urine.

Diacerein: This is used for the treatment of Osteoarthritis. It has also analgesic, antipyretic and anti-inflammatory activity. It release in vitro and directly inhibits InterLeukin-1(IL-1) synthesis, which is the main cytokine involved in cartilage destruction. Due to specific mode of action, it have been shown to have disease-modifying effect in experimental models of osteoarthritis and in human subjects with finger joint and knee osteoarthritis.

Oral bioavailability of Diacerein 56%. Concurrent intake of food delays the time to peak concentration but associated with a 25% increase in absorption. Therefore, diacerein is best given with food. Mainly binds with protein albumin. Diacerein is metabolized extensively (100%) in liver following oral dosing. Urinary excretion of diacerein in the form of its metabolites has ranged between 35% and 60%.
