Abstract: AIM: To investigate the efficacy and safety of liduofen in the treatment of patients with osteoarthritis of the knee joint.METHODS: A randomized, double-blind, parallel-controlled, multi-centre study was adapted to compare the efficacy and safety between liduofen and Olfen-75 in 136 patients.Patients were randomly assigned into two groups:liduofen group which was received 75 mg (diclofenac) Liduofen injection (n=69) once a day for seven days and Olfen group which was received 75 mg (diclofenac) Olfen-75 injection (n=67) once a day for seven days.RESULTS: After the treatment, similar improvements for rest pain, pain on exercise, swelling of joint, pressing pain of joint, knee joint bend extend function measured using a 10 cm visual analogue scale was performed in two groups.In Olfen-75 group, the rate of efficacy was 62.69% in the 3rd day, 95.76% in the 5th day and 97.88% in the 7th day. While in liduofen group, the rate of efficacy was 57.97% in the 3rd day, 93.87% in the 5th day and 96.94% in the 7th day.In liduofen and Olfen-75 groups, the progressive rates were 56.72% and 55.07%, respectively. The total improvement rates were 89.85% and 92.54% respectively (P>0.05), and the rates of side effects were 0% and 1.49%, respectively (P>0.05).CONCLUSION: Liduofen is an effective and safty drug inthe treatment of patients with osteoarthritis of the knee joint.
