Non-Surgical Management of Osteoarthritis: Nutraceuticals
CRYSTAL RIVER
--
Osteoarthritis (OA) is the most common form of arthritis,
affecting approximately 40 million people in the United States.
It is a leading cause of physical disability, increased need for
health care and results in impaired quality of life. By the year
2020, this disease is expected to affect nearly 60 million
Americans.
No non-surgical
management has been documented to affect the progression of
osteoarthritis. Typical pharmacologic therapy for use to combat
arthritis is presently a reduction in pain that is based on the
use of analgesics or non-steroidal anti-inflammatory medications.
These medications are most commonly prescribed for arthritis to
alleviate the pain associated with this disorder, but can cause
serious adverse effects such as gastrointestinal track, kidney and
bleeding disorders, particularly among the elderly.
The use of
over-the-counter nutraceuticals, such as glucosamine
sulfate and chondroitin sulfate, for the treatment of
osteoarthritis has recently attracted substantial attention in the
literature. Glucosamine is a precursor to a molecule called
glycosaminoglycan. This molecule is used in the formation and
repair of cartilage. Chondroitin is the most abundant
glycosaminoglycan in cartilage and is responsible for the
resiliency of cartilage.
Glucosamine is a
hexamine sugar derived from animal products that is a basic
building block for the biosynthesis of Type II collagen (the
cartilage in your joint). It is administered orally and to some
degree is absorbed from the gastrointestinal tract. The
recommended dose for glucosamine sulfate is 1500 mg daily and 1200
mg daily for chondroitin sulfate.
A recent study
evaluated the benefits of glucosamine and condroitin preparations
for osteoarthritis symptoms using meta-analysis combined with the
systematic quality assessments of clinical trials of these
preparations. The ultimate conclusion was that both glucosamine
and chondroid are likely to be effective therapies for the
symptomatic management of OA.
Treatment with these
joint supporting supplements is based on the theory that oral
consumption of glucosamine and chondroitin may increase the rate
and formation of new cartilage by providing the necessary building
blocks. It appears that these compounds are safe; however, the
efficacy in the treatment of OA requires further studies.
