The comparative efficacy of aceclofenac and ibuprofen in postoperative pain after third molar surgery

The aim of the present placebo-controlled, double-blind study was to evaluate the comparative efficacy of single doses of aceclofenac 150 mg and ibuprofen 400 mg in 217 patients with postoperative pain after third molar surgery. Outcome of primary efficacy was judged by overall assessment of the area under the curve (AUC) of graphs for pain intensity (AUC pain) pain relief (AUC relief), both measured from serial visual analogue scales over a 6 h investigation period. Other measures of efficacy included the rate of pain reduction in the first hour, the number of patients who took ‘escape’ analgesics and the time before they did, and an overall assessment of pain relief score on a five-point categorical scale. Ibuprofen 400 mg was significantly superior to placebo for pain relief (P < 0.01), degree of pain reduction in the first hour (P = 0.005), and the number of patients who required escape analgesia (P < 0.001), and the time before they did (P < 0.001). The outcome for patients treated with aceclofenac 150 mg was not significantly different from that of patients treated with placebo (P> 0.05). A single dose of ibuprofen 400 mg provided significant pain relief in the early postoperative period after third molar surgery, whereas a single dose of aceclofenac 150 mg was not effective in the management of postoperative pain after this operation.
