ABSTRACT

A randomized observational blind comparative clinical study was conducted to compare the antioxidant effect of vitamin C and E with paracetamol in patients of primary knee osteoarthritis.Subjects presenting with sign, symptoms of primary knee osteoarthritis were given paracetamol 1 gm (n=50) twice daily for 8 weeks and combinations of paracetamol 1gm bid with vitamin C (500 mg ) and E (200 IU) (n=50) twice daily for 8 weeks. Subjects completed an over all evaluation of symptoms relief on 2nd, 4th and 8th weeks of completed treatment were evaluated by clinical, routine laboratory and radiographic investigations for improvement of disease conditions, also for adverse drug reaction. On completion of 8 weeks of treatment it was observed that both the treatment group patients showed significant efficacy with better results with patients receiving antioxidant therapy in primary knee osteoarthritis patients (p<0.001) and adverse drug reaction were minor and none of patients complain of any severe adverse drug reaction. Present study indicate that antioxidant therapy can be used as an effective add on therapy in primary knee osteoarthritis.
