Abstract
Background Imrecoxib, a novel cyclooxygenase (COX-2) selective non-steroidal anti-inflammatory drug (NSAID), has been approved in China for more than 9 years. This study aimed to assess the efficacy and safety of imrecoxib compared with celecoxib for patients with moderate or severe acute pain following oral surgery. Methods Patients with moderate or severe pain within 6 hours following surgery were enrolled in this randomized, active-control trial. Patients were randomly assigned (1:1) to receive either imrecoxib or celecoxib. Pain assessments on the visual analog scale, verbal rating scale, and pain relief were conducted at 0.5, 1, 2, 4, 6, 9, 12, and 24 hours after the first dose. Adverse events were also recorded. Results Eighty-seven patients were approached from November 2018 to August 2019. Of these, 60 were eligible for randomization. Ultimately, 56 patients (imrecoxib group, n=27; celecoxib group, n=29) were included in the analysis. The difference in total pain relief (TOTPAR) between the imrecoxib and celecoxib groups was 1.03 [95% confidence interval (CI): −1.31–3.77], with the lower bound of the CI above the specified non-inferiority boundary. No perioperative complications were observed in the imrecoxib group during the 24-hour period after the first dose. Conclusions Imrecoxib could significantly relieve pain and has a non-inferior analgesic efficacy compared to celecoxib with good tolerance following oral surgery.
