PURPOSE: Our goal was to compare the analgesic efficacy and safety of single doses of intravenous parecoxib sodium, a prodrug of the novel cyclooxygenase (COX)-2-selective inhibitor valdecoxib, with intravenous ketorolac and placebo in postoperative oral surgery patients. PATIENTS AND METHODS: Eligible patients experiencing moderate to severe pain within 6 hours of surgery to extract 2 or more impacted third molars were randomized to receive a single dose of parecoxib sodium 1, 2, 5, 10, 20, 50, or 100 mg; ketorolac 30 mg; or placebo. Analgesic efficacy was assessed over a 24-hour treatment period or until rescue analgesia was required. RESULTS: Parecoxib sodium doses (particularly 50 and 100 mg) had a rapid onset of analgesia (within 11 minutes). The analgesic efficacy of parecoxib sodium 20 to 100 mg was similar to that of ketorolac 30 mg. Parecoxib sodium doses below 20 mg had suboptimal analgesic activity compared with placebo and ketorolac. A plateau of efficacy was observed at the parecoxib sodium 50-mg dose. Parecoxib sodium 50 and 100 mg had a significantly longer duration of analgesia than ketorolac 30 mg. All doses of parecoxib sodium were well tolerated. CONCLUSIONS: Parecoxib sodium, a novel parenteral prodrug of the COX-2-selective inhibitor valdecoxib, is as effective and longer acting at 50- and 100-mg intravenous doses than a standard dose of ketorolac 30 mg intravenously. Parecoxib sodium appears to be safe and well tolerated and, therefore, merits further evaluation in other models of postsurgical pain. |

目的： 我们的目标是比较单剂量静脉给药帕瑞昔布钠--新型环氧合酶（COX）-2选择性抑制剂伐地考昔的前体药物，与静脉给药酮咯酸和安慰剂对口腔手术患者术后镇痛的有效性和安全性。 患者和方法： 符合条件的患者---拔除2颗或更多颗智齿手术后6小时内有中度至重度疼痛的患者，被随机分配接受单剂量帕瑞昔布钠1、2、5、10、20、50或100毫克，酮咯酸30毫克或安慰剂。在给药后超过24小时期间或直到需要止痛前，对镇痛效果进行评价。 帕瑞昔布钠剂量（特别是50和100毫克）具有速效镇痛作用（11分钟内）。帕瑞昔布钠20-100毫克的镇痛效果与酮咯酸30毫克的镇痛效果类似。低于20毫克的帕瑞昔布钠剂量的镇痛活性，不及安慰剂和酮咯酸。帕瑞昔布钠50毫克剂量观察到疗效达到稳定水平。帕瑞昔布钠50和100毫克有与酮咯酸30毫克相比，镇痛作用持续时间更长。帕瑞昔布钠的所有剂量均具有良好的耐受性。 结论： 帕瑞昔布钠，一种新型COX-2选择性抑制剂伐地考昔的静脉用前体药物，以50 - 100毫克剂量静脉给药，与标准剂量酮咯酸30毫克静脉给药相比，具有良好且持续时间较长的镇痛作用。帕瑞昔布钠安全且耐受性良好，因此，值得在术后疼痛模型中进一步研究。 |
