Well-documented efficacy and fewer side effects than anti-inflammatory drugs make glucosamine sulfate a leading therapeutic option for treating and preventing osteoarthritis.
These amino sugars serve as components of polysaccharides, glycosaminoglycans and glycosphingolipids, which in turn provide structure to all cells in the living organism.3 Aside from providing a matrix for all cells, glycosaminoglycans (including hyaluronate, keratan sulfate, heparan sulfate and heparin) are the fundamental subunits of cartilage, synovial fluid, intervertebral disks, lung tissue, vessel walls and intestinal mucosa.3 Glucosamine, therefore, by serving as an essential constituent of these glycosaminoglycans, is an even more basic subunit of cartilage and the other structures.

Glucosamine is a naturally occurring sugar that is a basic building block of several important constituents of articular (joint) cartilage1.
Seven RCTs involving placebo, which included pain relief as a measurable outcome, found that glucosamine gave greater pain relief.
A second review identified six placebo-controlled trials, involving a total of 911 patients, which evaluated glucosamine in osteoarthritis.
Whether these joint changes are of clinical significance is not clear from this study and further work is needed to determine if glucosamine has a role as a disease-modifying agent.
No drug interactions have been reported between glucosamine and conventional medicines to date.
No reports of a clinically significant effect on blood sugar have been found in the literature but monitoring remains advisable.

Query: Is it safe for people with diabetes to take glucosamine?
In 1991, Marshall et al [3] advanced the hypothesis that routing of incoming glucose through the hexosamine biosynthetic pathway plays a role in the development of insulin resistance.
Few diabetic patients participated in this study; however, analysis of a subset of patients with high baseline glucose levels at entry showed a similar pattern, with a tendency for a fall in plasma glucose in those taking glucosamine.
Whilst further long-term safety studies are needed for glucosamine, existing data does not indicate that oral administration adversely affects hyperglycaemic control in diabetes.

As a person ages, the cartilage that cushions the joints often loses its ability to support healthy cellular growth.
These preparations may cause side effects like slowing down the body's rate of cartilage replacement and actually destroying c a rt i l a g e .1 Other side effects include: gastrointestinal tract damage, hemorrhaging, tinnitus (ringing in the ears), edema (fluid retention) and sometimes kidney and liver damage.2 After these products no longer are effective, you can choose to: 1) live with it or 2) undergo radical medical procedures like joint replacement surgery.
Glucosamine is a n e c e s s a ry nutrient in the production of cartilage and synovial fluid.
Glucosamine hydrochloride demonstrates more stability, p u r i t y, and higher concentration when compared to glucosamine sulfate.* Published clinical studies---including six double-blind studies---re p o rt significant substantial and durable efficacy, without side effects.3 The results of these studies with glucosamine have been published in several medical journals.

The intrinsic analgesic activity of glucosamine and chondroitin could not be evaluated quantitatively since patients were allowed to use rescue medication such as NSAIDs.
Against the background of the recent withdrawal of the licence for the use of paroxetine in children, this company-sponsored study suggests that sertraline is an effective and well-tolerated short-term treatment for children and adolescents with major depressive disorder (MDD).
There was no reduction of AOM episodes in the pneumococcal vaccine groups compared with controls, with 58% of children in the treatment groups experiencing at least one episode of AOM, and 56% in the control groups (rate ratio 1.25 episodes per person-year [95% CI 0.99-1.57]).

Glucosamine: A potential disease-modifying agent in osteoarthritis?
Eligible patients were those over 50 years of age with osteoarthritis of the knee that met the diagnostic criteria of the American College of Rheumatology.
The active treatment consisted of 1500-mg tablets of glucosamine sulfate, produced commercially by the company that sponsored the study.
The primary outcome measures were joint-space narrowing in the affected knee and symptom relief.
The width of the joint space was assessed using 2 methods: visually by a radiologist unaware of the patient's treatment assignment, and automatically by means of a computer analysis of digitized radiographs.
The measurements of joint-space narrowing, however, were objective and raise the possibility of a disease-modifying effect.

Glucosamine is one of the fastest growing sports nutrition supplements on the market at the moment and is becoming increasingly known for its varied benefits.
The claimed benefits of glucosamine supplementation include quickened recovery from connective tissue injuries, reduced joint pain, increased joint lubrication and anti-inflammation of joints.
Fig. 1 Anatomy of the knee showing position of cartilage Glucosamine sulphate (the type normally found in supplements) is the sulphate derivative of the natural aminosaccharide glucosamine.
Glucosamine has been shown to be as effective as non-steroidal anti-inflammatory drugs (NSAIDs), with fewer negative reactions for use in the elimination of pain and the restoration of joint mobility (Vaz, 1982).
In patients with osteoarthritis, glucosamine has been shown to slow the progression of the symptoms.

Four formulations were developed to represent clinically relevant dosages of Glucosamine sulfate at 500mg and Glucosamine hydrochloride-Chondroitin sulfate at 500mg400mg, each for 12- and 24-hour controlled release delivery.
Near zero-order release of drug content over 12 to 24 hours was achieved for all optimized formulations; no burst effect was evident and the contents were 100% released.
In addition, tablet hardness, friability and content uniformity were all within acceptable limits outlined in the USP 24.
Powder flow characterization was performed on raw materials and final formula blends using a Hosakawa Micron Powder Tester PT-N (Summit, NJ) to determine flowability and floodability properties.

Glucosamine and chondroitin sulfates are natural substances widely acclaimed to relieve osteoarthritis, or inflammation of the joints.
Depending on the disease's severity, pain may decrease with such medications as nonsteroidal anti-inflammatory drugs (NSAIDs), simple pain medications and various other third-line agents.
These supplements are derived from such marine-animal skeletons as shark cartilage, and can also be produced synthetically.
Since human joints are composed of similar glycoproteins and because glucosaminoglycans are found in human cartilage, it is believed that glucosamine and chondroitin stimulate the formation of, or replace, parts of joints lost to osteoarthritis.
Glucosamine has been shown to be of little benefit for patients with severe osteoarthritis.

Osteoarthritis is the most common form of arthritis, and the most suffered chronic condition of old age.
It is a "wear" and "tear" disease, causing the breakdown of cartilage in the joints which leads to stiffness and pain, predominantly affecting the knees, hip, spine and finger joints.
Rheumatoid arthritis is another common type of arthritis that affects about one per cent of the population world-wide, with women being three times more likely than men to suffer.
More recent research, conducted mainly in Europe, has shown that there is a nutritional supplement that not only eases the debilitating pain of arthritis, but also works on repairing cartilage.
