Chondroitin sulfate, one of five classes of glycosaminoglycans, has been widely used in the treatment of osteoarthritis. Chondroitin sulfate reduces inflammation mediators and the apoptotic process and is able to reduce protein production of inflammatory cytokines, iNOS and MMPs.
Glucosamine is a popular nutritional supplement and natural component of cartilage that is frequently combined with chondroitin sulfate and used for osteoarthritis and nonspecific joint pain. Glucosamine has been implicated in isolated case reports in causing clinically apparent liver injury, but the role of glucosamine as opposed to other herbal components or contaminants has not been shown, and liver injury due to glucosamine or chondroitin must be very rare if it occurs at all.|Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
