Study of oral glucosamine, methylsulfonylmethane and their combination in osteoarthritis of the knee
Keywords:Joint pains, Physical function, Efficacy, Adverse effects
Background: Osteoarthritis (OA) of the knee is the most common degenerative joint disorder that results in disability and increased morbidity. Conventional treatment of OA with non-steroidal anti-inﬂammatory drugs (NSAIDs) often leads to serious adverse side effects that may increase morbidity and mortality. Glucosamine and Methylsulfonylmethane (MSM) have anti-inflammatory and analgesic properties which may supplement NSAIDs. Hence this study was aimed to determine the effectiveness and safety of these drugs in the management of knee OA
Methods: 76 (63.33%) female and 44 (36.67%) male patients of OA of the knees were divided equally into four groups depending upon the therapy with Glucosamine or MSM or their combination (study groups) or none of them (control group) for 12 weeks. After the written consent, a detail Clinical History& Examination, Biochemical investigations, X-rays of chest and knees and ECG were done. The outcome of the treatment was assessed by Western Ontario and McMaster University Osteoarthritis (WOMAC) Index and for any adverse drug effects.
Results: After 12 weeks of study there was significant decrease in mean WOMAC pain scores (27.29-39.13) and total aggregate scores (23.53-37.14%) in study groups (p<0.01-p<0.001) as compared to control group (14.28 % and 8.82% respectively). Besides the relief of pain and improvement in physical functions were superior in patients treated with combination therapy.
Conclusions: This study showed Glucosamine & MSM are effective in the management of OA of knee and are safe health supplement to NSAIDs while their combination was more superior and effective.
