摘　　要：目的根据难溶性药物的不同特点,分析影响其溶解速度的因素,采取适当的配置方法,加快难溶性药物的溶解速度,减少配置所需时间,提高配置效率。方法将门冬氨酸鸟氨酸、美洛西林钠舒巴坦钠、替考拉宁、奥美拉唑钠注射液、亚胺培南西司他丁钠等5种难溶性药物的常规配药方法作为对照组,以增加溶媒量、配置前敲松药瓶内药粉、减少泡沫产生、使用专用溶媒及提高溶解温度等改进后的方法分别作为5种药物配置的实验组进行观察和对比实验,药物配置完成至完全溶解为澄清透明液体计时。结果门冬氨酸鸟氨酸、美洛西林钠舒巴坦钠、替考拉宁、奥美拉唑钠注射液、亚胺培南西司他丁钠等药物实验组完全溶解为澄清透明液体平均需时分别为(42±5)s、(3±1)min、(5±1)min、(5±3)s、(2±1)min,显著少于对照组平均需时(246±35)s、(30±3)min、(10±3)min、(10±5)s、(10±1)min。5种药物经过改进前后不同配置方法比较,完全溶解时间差异有统计学意义(P<0.05)。结论采取适当增加溶媒量、加药前敲松药粉、减少加药过程中泡沫产生、专用溶媒的使用及提高溶解温度等溶解方法,可有效缩短难溶性药物的溶解时间,提高静脉用药配置效率。Objective The article was to speed up the dissolution rate of poorly soluble drugs, reduce the configuration time and improve the allocative efficiency by analysis on factors influencing dissolution and adoption of proper allocative approaches accord-ing to different characteristics of insaluble drugs. Methods 5 insaluable drugs were chosen for the study, which were ornithine as-partate, mezlocillin sodium and sulbactam sodium, teicoplanin, omeprazole sodium injection and imipenem and cilastatin sodium.The control group were allocated by routine configuration approach, while the experiment group were improved by increasing the amount of solvent, loosing the powder inside the bottle before configuration, reducing the bubble, adopting special solvent and increasing the dis-solution temperature.Observation and comparative experiment were made on two groups along with the timing from configuration to com-plete dissolution into clear transparent liquid. Results As to the average complete dissolution time of 5 drugs, significant difference was found between two groups（[42±5]s vs [246±35]s, [3±1]min vs [30±3]min, [5±1]min vs [10±3]min, [5±3]min vs [10± 5]min, [2±1]min vs [10±1]min, P30.05）.Compared with the control group, the dissolution time of 5 drugs was cut down by 83%, 90%, 50%, 50%, 80%in experiment group. Conclusion Appropriate increase of solvent, loose powder, bubble reduction, special solvent and increased solution temperature contribute to shortening the dissolution time of insoluble drugs and improving the configura-tion efficiency of pharmacy intravenous admixture.
