💊 Profile

Glucosamine is a natural substance found in chitin, mucoproteins, and mucopolysaccharides. It is involved in the manufacture of glycosaminoglycan, which forms cartilage tissue in the body; glucosamine is also present in tendons and ligaments. Glucosamine must be synthesised by the body but the ability to do this declines with age. Glucosamine and its salts have therefore been advocated in the treatment of rheumatic disorders including osteoarthritis. Glucosamine may be isolated from chitin or prepared synthetically; glucosamine sulfate and hydriodide, have also been used.

Effects on glucose metabolism.

Glucosamine has a role in glucose metabolism, increasing insulin resistance in skeletal muscle,1,2 which has raised concerns about its safety profile in diabetic patients.3 However, alteration of glycaemic homoeostasis was not found in a 3-year randomised controlled study in patients without diabetes.4 A review5 of the literature found limited data on diabetic patients taking glucosamine supplements, and recommended close monitoring of blood glucose levels in this group until more data are available.

Glucosamine and its salts are widely available as licensed products or so-called ‘health supplements’ used for the management of osteoarthritis; they may be combined with other substances supposed to be of benefit, including chondroitin, vitamins, and various herbs. Meta-analyses1,2 of randomised placebo-controlled studies concluded that while there was some evidence for efficacy of glucosamine and chondroitin in the treatment of osteoarthritis, methodological flaws and publication bias had led to exaggeration of its potential benefit,1 and that further studies are needed to fully characterise their disease-modifying properties.2 A systematic review3 of the use of glucosamine for osteoarthritis that included later controlled studies concluded that glucosamine is as safe as placebo but there was little evidence of improvement in pain or function. A further randomised controlled study4 in 222 patients with hip osteoarthritis found no benefit after treatment with glucosamine for 2 years compared with placebo, and a meta-analysis5 of controlled studies of chondroitin for osteoarthritis of the knee or hip concluded that chondroitin had minimal or no benefit. Further research is needed to confirm whether there are differences in efficacy between glucosamine salts, preparations, or routes, and when used with other agents (e.g. chondroitin) or in different patient subgroups.3 A large multicentre double-blind study6 in 1583 patients with symptomatic knee osteoarthritis to compare glucosamine and chondroitin, either alone or in combination, found no clear evidence of benefit in pain reduction compared with placebo or celecoxib, although there was a tendency to more positive results in a subset of patients with moderate to severe knee pain.

Skin reactions.

The Australian Adverse Drug Reactions Advisory Committee (ADRAC)1 has received 51 reports of allergic skin reactions with glucosamine, including erythematous rash, angioedema, urticaria, rash, and pruritus. It was noted that some preparations contain glucosamine sourced from seafood and therefore people with an allergy to shellfish may be at greater risk for hypersensitivity reactions.
