Oxaceprol versus tramadol for knee osteoarthritis: A randomized controlled trial. To assess efficacy and safety of oxaceprol, a hydroxyproline derivative with putative mechanism of action different from traditional nonsteroidal anti-inflammatory drugs, in symptomatic knee osteoarthritis, in comparison to tramadol. A parallel group, double-blind, randomized controlled trial was conducted with ambulatory patients over 50 years age suffering from knee osteoarthritis causing pain of at least moderate intensity. Patients were randomized to receive either oxaceprol 200 mg thrice daily or tramadol 50 mg thrice daily for 12 weeks. The primary efficacy variable was symptom relief as assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) version 3.1 for pain, stiffness
Oxaceprol--a randomised, placebo-controlled clinical study in osteoarthritis with a non-conventional non-steroidal anti-inflammatory drug. To evaluate efficacy of therapy with oxaceprol in the treatment of symptomatic osteoarthritis of knee or hip. A 3-week prospective, multicentric, randomised, double-blind, placebo-controlled study with 167 patients aged between 40 and 75 years with painful and radiologically confirmed knee or hip osteoarthritis. Patients were randomly assigned to receive oxaceprol 1200 mg/day or placebo for 3 weeks. At inclusion, osteoarthritis symptoms were minimum pain following exercise (standardised as pain after climbing 12-15 stairs) of 40 to 90 mm on a 100 mm pain scale and difficulties in climbing stairs. Efficacy criteria were changes in pain shown in a visual analogue
Oxaceprol is a well-tolerated therapy for osteoarthritis with efficacy equivalent to diclofenac. The therapeutic equivalence and safety of treatment for 21 days with 400 mg t.i.d. oxaceprol (n = 132) and 50 mg t.i.d. diclofenac (n = 131) were assessed in a multicentre, randomised, double-blind study of a mixed population of patients with osteoarthritis of the knee and/or hip. In a per-protocol analysis of efficacy, the mean Lequesne index decreased by 2.5 points in the oxaceprol group (n = 109) and by 2.8 points in the diclofenac group (n = 109). The 95% confidence interval for the end-point difference revealed therapeutic equivalence. This was confirmed by assessments (visual analogue scale) of pain at rest, weight-bearing pain, pain on standing and pain on movement, all of which decreased
Oxaceprol is as effective as diclofenac in the therapy of osteoarthritis of the knee and hip. In this multicentre (five centres in Germany), randomised, double-blind, comparative study, 150 patients with painful degenerative joint disease according to EULAR criteria received either oxaceprol (200 mg three times daily) or diclofenac (25 mg three times daily) for 20 days. Joint function between the treatments. The incidence of adverse drug reactions was similar in both groups but oxaceprol induced milder symptoms. Oxaceprol is as effective and better tolerated than diclofenac in the treatment of osteoarthritis.
