This randomised, double-blind, placebo-controlled, parallel-group study compared the efficacy and tolerability of lumiracoxib (a novel COX-2 selective inhibitor) with rofecoxib, celecoxib and placebo in patients with moderate-to-severe post-operative dental pain. Following third molar extraction, patients received single oral doses of lumiracoxib 400 mg, rofecoxib 50 mg, celecoxib 200 mg or placebo (n = 355). Additional patients from a similar study, assigned to lumiracoxib, rofecoxib or placebo (n = 155), were included for analysis of the primary variable, Summed Pain Intensity Difference over the first 8 h post dose (SPID-8). For SPID-8, lumiracoxib was superior to rofecoxib (p < 0.05), celecoxib (p < 0.001) and placebo (p < 0.001). Lumiracoxib demonstrated the fastest onset of analgesia and the longest time to rescue medication use. Patient global evaluation of lumiracoxib was comparable to rofecoxib and superior to celecoxib and placebo. All treatments were well tolerated. Lumiracoxib 400 mg provides rapid, effective and sustained relief of post-operative dental pain, comparable or superior to rofecoxib.

This randomised, double-blind study compared single dose lumiracoxib (a cyclooxygenase-2 selective inhibitor) 100 and 400 mg, ibuprofen 400 mg and placebo in patients with postoperative dental pain over 12 h. The primary efficacy variable was pain intensity difference. Lumiracoxib 400 mg and ibuprofen were superior to placebo from 1 to 12 h post dose while lumiracoxib 100 mg was superior from 1.5 to 9 h. Lumiracoxib 400 mg demonstrated the fastest median time to onset of analgesia (37.4 min) followed by ibuprofen (41.5), and lumiracoxib 100 mg (52.4; all p < or = 0.001 vs. placebo). Median time to rescue medication (h) was longer for lumiracoxib 400 mg (> or = 12), lumiracoxib 100 mg (approximately 7) and ibuprofen (approximately 8) than placebo (approximately 2; all p < or = 0.001 vs. placebo). Patients rated lumiracoxib 400 mg superior to the other active treatments (p < 0.05); lumiracoxib 100 mg was comparable with ibuprofen and superior to placebo (p < 0.001). Lumiracoxib provided rapid, effective and well-tolerated analgesia.

Cyclo-oxygenase-2 selective inhibitors are frequently used to manage osteoarthritis. We compared the analgesic efficacy of the novel cyclo-oxygenase-2 selective inhibitor lumiracoxib (Prexige) versus placebo and celecoxib in patients with knee osteoarthritis. This seven day, double-blind, placebo and active comparator controlled, parallel group study included 364 patients aged > or = 50 years with moderate-to-severe symptomatic knee osteoarthritis. Patients received lumiracoxib 400 mg/day (four times the recommended chronic dose in osteoarthritis; n = 144), placebo (n = 75), or celecoxib 200 mg twice daily (n = 145). The primary variable was actual pain intensity difference (100 mm visual-analogue scale) between baseline and the mean of three hour and five hour assessments after the first dose. Actual pain intensity difference, average and worst pain, pain relief and functional status (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]) were measured over seven days. Patients also completed a global evaluation of treatment effect at study end or premature discontinuation. For the primary variable, the superiority of lumiracoxib versus placebo, the noninferiority of lumiracoxib versus celecoxib, and the superiority of lumiracoxib versus celecoxib were assessed by closed test procedure adjusting for multiplicity, thereby maintaining the overall 5% significance level. In addition, celecoxib was assessed versus placebo in a predefined exploratory manner to assess trial sensitivity. Lumiracoxib provided better analgesia than placebo 3-5 hours after the first dose (P = 0.004) through to study end. The estimated difference between lumiracoxib and celecoxib 3-5 hours after the first dose was not significant (P = 0.185). Celecoxib was not significantly different from placebo in this analysis (P = 0.069). At study end 13.9% of lumiracoxib-treated patients reported complete pain relief versus 5.5% and 5.3% of celecoxib and placebo recipients, respectively. WOMAC total and subscales improved for both active treatments versus placebo except for difficulty in performing daily activities, for which celecoxib just failed to achieve significance (P = 0.056). In the patient's global evaluation of treatment effect, 58.1% of patients receiving lumiracoxib rated treatment as 'excellent' or 'good', versus 48.6% of celecoxib and 25.3% of placebo patients. Lumiracoxib was well tolerated. The overall incidence of adverse events was similar across treatment groups.
