Parecoxib sodium administered over several days reduces pain after gynecologic surgery via laparotomy

Abstract

Abstract Study Objective To assess the analgesic efficacy of a multidose, multiday regimen of intravenous (IV) parecoxib sodium (parecoxib). Design Multicenter, randomized, double-blind, placebo-controlled, parallel-group trial. Setting Postoperative recovery area and inpatient care facility. Patients 422 patients who had undergone gynecologic surgery via laparotomy participated (day 1), and 414 patients were randomized (day 2). Interventions After surgery on day 1, all patients received parecoxib 40 mg (IV), followed by 20 mg (IV) one to 12 hours later; patients were then randomized to receive parecoxib 20 mg (IV) twice daily (n = 211) or placebo (IV) twice daily (n = 203) on days 2 to 5. Patients were permitted rescue medication as needed. Measurements Primary efficacy measures were summed pain intensity through 24 hours (SPI-24) and Patient's Global Evaluation of Study Medication on days 2 and 3. Main Results In the parecoxib treatment group, 24-hour summed pain intensity scores were significantly lower than in the placebo treatment group ( P P Conclusion Multidose parecoxib was well tolerated over several days and provided improved pain control after gynecologic surgery.
