A 6-month repeated dose toxicity study with 1-month recovery test of sodium N-[2-[4-(2,2-dimethylpropionyloxy) phenylsulfonylamino] benzoyl] aminoacetate tetrahydrate (ONO-5046.Na), a novel neutrophil elastase inhibitor, was conducted in Sprague-Dawley (SD) rats. The rats of both sexes were administered ONO-5046.Na intravenously at a daily dose of 0 (vehicle control), 18.75, 37.5 or 75 mg/kg. ONO-5046.Na did not affect clinical signs, body weight, food consumption, opthalmology, urinalysis, hematology, blood chemistry, organ weight, necropsy or histopathology at any dose. These results indicate that the NOAEL of ONO-5046.Na in rats is 75 mg/kg/day for both sexes in this study.
对新型中性粒细胞弹性蛋白酶抑制剂N-[2-[4-(2,2-二甲基丙酰氧基)苯磺酰氨基]苯甲酰基]氨基乙酸钠四水合物（ONO-5046.Na）进行了为期6个月的重复剂量毒性研究，并进行了为期1个月的恢复试验，实验动物为Sprague-Dawley（SD）大鼠。雌雄大鼠均静脉注射ONO-5046.Na，日剂量分别为0（溶剂对照）、18.75、37.5或75 mg/kg。在任何剂量下，ONO-5046.Na均未影响临床体征、体重、食物消耗量、眼科检查、尿液分析、血液学、血液化学、器官重量、尸检或组织病理学。这些结果表明，在本研究中，ONO-5046.Na对大鼠的无观察到有害作用水平（NOAEL）为雌雄均75 mg/kg/天。
