title: Intravenous parecoxib sodium foracute pain after orthopedic knee surgery.
abstract: Our objective in a randomized, multicenter, double-blind, parallel-group, placebo- and active-controlled study was to evaluate and compare the analgesic effectiveness of single intravenous (IV) doses of parecoxib sodium 20 and 40 mg, morphine 4 mg, and ketorolac 30 mg in the postsurgical orthopedic pain model. After undergoing unilateral total knee replacement surgery, 208 healthy adult patients were randomized to receive placebo or a study drug within 6 hours of discontinuation of patient-controlled analgesia on postoperative day 1. Onset of analgesia was similarly rapid with IV parecoxib sodium 40 mg, morphine, and ketorolac. Level and duration of analgesia were significantly superior with parecoxib sodium than with morphine and were similar for parecoxib sodium and ketorolac. Parecoxib sodium was safe and well tolerated. In conclusion, IV parecoxib sodium 40 mg is as effective as ketorolac 30 mg and is more effective than morphine 4 mg and therefore has potential widespread utility in acute postoperative pain management.
