Leiner reports NIH study shows glucosamine/chondroitin combination effective in treating knee pain

By Angela McDaniels

Seattle, Nov. 10 - Leiner Health Products said new data confirms a combination of nutritional supplements glucosamine and chondroitin effectively relieves knee pain associated with osteoarthritis. The company manufactures vitamins and other supplements.

Lead researcher Daniel O. Clegg of the University of Utah will present findings from the study on Monday at the American College of Rheumatology's Scientific Meeting in San Diego, Calif.

The $14 million Glucosamine/Chondroitin Arthritis Intervention Trial, funded by the National Institutes of Health, evaluated the efficacy and safety of glucosamine and chondroitin in 1,258 people. Patients were given glucosamine, chondroitin, the glucosamine/chondroitin combination, Celebrex or placebo daily for six months.

Of particular note, the group taking the glucosamine/chondroitin combination experienced greater pain relief than those treated with Celebrex group, and previous research indicates glucosamine is as effective as non-steroidal anti-inflammatory drugs in reducing osteoarthritis pain with fewer gastrointestinal side effects, the company said.

Leiner Health Products, headquartered in Carson, Calif., manufactures vitamins, minerals, supplements and over-the-counter pharmaceuticals.
