A nanocrystal intravenous (IV) formulation of meloxicam is being studied with the aim of providing postoperative analgesia.
This randomized, multicenter, double-blind, placebo-controlled trial evaluated meloxicam IV 30 mg or placebo (≤ 3 doses) in 219 subjects undergoing abdominoplasty. The primary endpoint was the summed pain intensity difference over 24 hours postdose (SPID).
Meloxicam IV-treated subjects had a statistically significant reduction in the least squares mean of SPID compared with placebo-treated subjects (-4,262.1 versus -3,535.7; = 0.0145). Meloxicam IV was associated with statistically significant differences over placebo on several other secondary endpoints, including other SPID intervals (ie, SPID, SPID, and SPID), achievement of perceptible pain relief, the proportion of subjects with a ≥ 30% improvement in the first 24 hours, and Patient Global Assessment of pain at hour 48. Meloxicam IV was also associated with a reduction in the number of subjects receiving opioid rescue medication during hours 24-48 and the total number of doses of opioid rescue analgesia. Meloxicam IV was generally well tolerated, with the numbers and frequencies of adverse events similar to that of the placebo group. There was no evidence of an increased risk of adverse events commonly associated with nonsteroidal anti-inflammatory drugs including bleeding, thrombotic, cardiovascular, renal, hepatic, cardiovascular, injection site, and wound healing events.
Meloxicam IV provided sustained pain relief and generally was well tolerated in subjects with moderate-to-severe pain following abdominoplasty.
正在研究美洛昔康的纳米晶体静脉注射(IV)制剂,旨在提供术后镇痛。
这项随机、多中心、双盲、安慰剂对照试验评估了219例接受腹部整形手术的受试者使用30毫克美洛昔康静脉注射剂或安慰剂(≤3剂)的情况。主要终点是给药后24小时内的疼痛强度差值总和(SPID)。
与安慰剂治疗的受试者相比,美洛昔康静脉注射治疗的受试者的SPID最小二乘均值有统计学显著降低(-4262.1对-3535.7;P = 0.0145)。在其他几个次要终点上,美洛昔康静脉注射剂与安慰剂相比有统计学显著差异,包括其他SPID时间段(即SPID、SPID和SPID)、实现可感知的疼痛缓解、在前24小时内改善≥30%的受试者比例以及48小时时患者对疼痛的整体评估。美洛昔康静脉注射剂还与24 - 48小时内接受阿片类救援药物的受试者数量减少以及阿片类救援镇痛的总剂量减少有关。美洛昔康静脉注射剂总体耐受性良好,不良事件的数量和频率与安慰剂组相似。没有证据表明与非甾体抗炎药常见相关的不良事件风险增加,包括出血、血栓形成、心血管、肾脏、肝脏、心血管、注射部位和伤口愈合事件。
美洛昔康静脉注射剂在腹部整形术后中重度疼痛的受试者中提供了持续的疼痛缓解,且总体耐受性良好。
