Effectiveness of diclofenac, ketorolac and etoricoxib in the treatment of acute pain from ankle fracture.

Abstract

Tissue degeneration, infection, inflammation, cancer, trauma, surgery and limb fractures all produce pain. Each of these physiological abnormalities requires a therapeutic approach different from the last. In acute pain, caused by fracture, several classes of analgesics have been utilized. These basic remedies for analgesia, however, are still confined to a small number of medications, including nonsteroidal anti-inflammatory drugs (NSAIDs), local anesthetics and opioids. In addition, most of these drugs have side effects, limiting their use in clinical practice. The purpose of this study was to compare the efficacy of three NSAIDs to relief acute pain caused by ankle fracture. Sixty subjects with ankle fracture were randomized to receive ketorolac, diclofenac, or etoricoxib, every 12 hours in a prospective, double-blind study. Forty-nine patients completed the study. The subjects' assessments of ankle pain on the visual analog scale and a Likert scale showed a significant reduction from baseline over 24 hr, regardless the treatment group. All treatments showed a similar profile in pain reduction. Etoricoxib, diclofenac and ketorolac twice daily are a rapid and effective treatment for acute pain. All the regimens were well tolerated in this study.
