Drug information of Glucosamine
Glucosamine is a naturally occurring substance found in bones, bone marrow, shellfish and fungus.
It is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis.
Glucosamine has been used in alternative medicine as an aid to relieving joint pain, swelling, and stiffness caused by arthritis
Mechanism of effect
Glucosamine is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Oral glucosamine is commonly used for the treatment of osteoarthritis.
Since glucosamine is a precursor for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis. Its use as a therapy for osteoarthritis appears safe, but there is conflicting evidence as to its effectiveness with more recent studies showing limited to no clinical benefit of use.
Osteoarthritis is characterized by the progressive degeneration of cartilage glycosaminoglycans. The formation of glucosamine is the rate limiting step in glycosaminoglycans synthesis thus the addition is glucosamine, would in theory provide a building block towards the synthesis of glycosaminoglycans and thus slow down the progression of osteoarthritis.
