Purpose: Our purpose in this study was to compare the efficacy, tolerability, and safety of a multicomponent antiinflammatory preparation containing glucosamine hydrochloride (g hydrochloride) or plain glucosamine sulfate (g sulfate) with that of a nonsteroidal antiinflammatory drug (NSAID), aceclofenac, in the treatment of knee osteoarthritis.
Methods: Forty-five patients with active osteoarthritis of the knee joint were randomized to receive g hydrochloride, g sulfate, or aceclofenac for 12 weeks. The patients were evaluated by the Western Ontario and McMaster Universities (WOMAC) osteoarthritis-index scale, and bone-resorption assessment was
done by measuring levels of pyridinoline and deoxypyridinoline from morning first-void urine samples of patients at baseline and at every 4-week interval until 4 weeks after drug discontinuation.
Antero-posterior radiographs of affected knees were taken at baseline and after 12 weeks of therapy.
