Efficacy and tolerability of oral enzyme therapy as compared to diclofenac in active osteoarthrosis of knee joint: an open randomized controlled clinical trial

J Assoc Physicians India. 2001 Jun;49:617-21.


Objective: To compare the efficacy and tolerability of an oral enzyme preparation (Phlogenzym) with that of an NSAID (diclofenac) in the treatment of active osteoarthrosis.

Methods: Prospective, randomized, controlled, single-blind study of seven weeks duration at a tertiary care centre wherein 50 patients aged 40-75 years, with activated osteoarthrosis of knee joint were randomized to receive phlogenzym tablets (2-3 tablets, bid) or diclofenac sodium 50 mg bid for three weeks.

Results: At the end of therapy (three weeks) and at follow-up visit at seven weeks there was reduction in pain and joint tenderness and swelling in both groups, and slight improvement in the range of movement in the study group. The reduction in joint tenderness was greater (p < 0.05) in the study group receiving phlogenzym.

Conclusion: Phlogenzym is as efficacious and well tolerated as diclofenac sodium in the management of active osteoarthrosis over three weeks of treatment.
