【摘要】 目的研究蒙脱石散对几种常见喹诺酮类药物体外的吸附作用。方法将临床常用的几种喹诺酮类药物融入水及人工胃液中加入蒙脱石散,用紫外分光光度法进行测定比较。结果氧氟沙星、诺氟沙星、吡哌酸在水溶液中难溶,而在人工胃液中蒙脱石的吸附率均在98%以上;盐酸洛美沙星、盐酸环丙沙星、甲磺酸培氟沙星无论是在水溶液中还是在人工胃液中,蒙脱石散的吸附率均超过99%。结论蒙脱石散对于常用的几种喹诺酮类药物均具有明显的吸附作用,在实际操作中应严格控制两者的使用间隔时间。更多还原

【Abstract】 Objective To study the adsorption of montmorillonite powder on several common quinolones objects in vitro. Methods Several commonly used clinical quinolones integration into the water and artificial gastric juice,added montmorillonite powder,measured by ultraviolet spectrophotometry. Results Ofloxacin,norfloxacin,pipemidate insoluble in aqueous solutions,and adsorption rate of montmorillonite in artificial gastric juice was more than 98%; lomefloxacin hydrochloride,ciprofloxacin hydrochloride,mesylate pefloxacin whether in water or in artificial gastric juice,montmorillonite adsorption rate were over 99%. Conclusion Montmorillonite powder has obvious adsorption for several common quinolones,should strictly control the use of both interval time in the actual operation.更多还原
