Lumiracoxib 400 mg Compared With Celecoxib 400 mg and Placebo for Treating Pain Following Dental Surgery: A Randomized, Controlled Trial

Abstract

This randomized, double-blinded, double-dummy, parallel-group, single-center study compared a single dose of the novel selective COX-2 inhibitor lumiracoxib (400 mg), with celecoxib (400 mg) or placebo in dental pain. Patients > or =17 years with moderate-to-severe dental pain were recruited after surgical extraction of 2 or more partially or fully bony impacted molars. Pain intensity was measured using the categorical scale and the primary efficacy variable was the summed pain intensity difference over 8 hours after dosing (SPID-8). Patient disposition and demographics were comparable between lumiracoxib 400 mg (n = 156), celecoxib 400 mg (n = 156), and placebo (n = 52) groups. Lumiracoxib was statistically superior (P < .001) to both celecoxib and placebo in reducing pain intensity (SPID-8; least-squares means: 8.31, lumiracoxib; 4.26, celecoxib; -1.87, placebo). Significantly more patients treated with lumiracoxib (58.9%) considered treatment to be good or excellent compared with celecoxib and placebo (42.3% and 5.7%, respectively; P = .001). Lumiracoxib was superior to celecoxib and placebo for all other secondary efficacy variables. All treatments were well-tolerated. In conclusion, 400 mg lumiracoxib was well-tolerated and provided significantly superior analgesia to 400 mg celecoxib or placebo in patients with moderate-to-severe pain after dental surgery. In a randomized, double-blinded, double-dummy, parallel-group, single-center study, a single dose of the novel selective COX-2 inhibitor lumiracoxib (400 mg) was well-tolerated and provided significantly superior analgesia to 400 mg celecoxib or placebo in patients with moderate-to-severe dental pain after surgical extraction of impacted molars.
