盐酸洛美沙星与甲硝唑氯化钠注射液配伍稳定性考察
连续测定5d,代入回归方程,计算RSD。见表1。表1日内和日间精密度结果(%。n=5)2.1.4回收率试验精密称取洛美沙星、甲硝唑对照品适量,[link widoczny dla zalogowanych],用0.9%NS配制成含洛美沙星、甲硝唑分别为1.86、3.96/~g/mL,5.58、11.88og/mL,9.30、19.80og/mL的3种不同浓度混合溶液(每种混合溶液设3组平行试验),并在262、282、319、354nm处测定吸收度值,代入相应的回归方程,计算出各自的回收率。结果见表2。表2洛美沙星和甲硝唑的回收率(,l=3J2.2配伍液稳定性考察2.2.1外观、pH值、含量变化将新配制的配伍液,分别置于室温、37℃恒温水浴中,在0…123…456h末,[link widoczny dla zalogowanych]。观察其外观,测pH值。同样的时间间隔,精密吸取1mL置于100mL容量瓶,用0.9%NS稀释,定容,摇匀,在262、282、319、354nm处测吸收度,代入相应回归方程计算,并以0h含量为100%,计算其他时间的相对百分含量。见表3、表4。表3盐酸洛美沙星与甲硝唑氯化钠注射液配伍(室温)Remedies,2008,v0l_11,No.52.2.2吸收曲线的变化在含量测定的同时,以0.9%NS为空白,[link widoczny dla zalogowanych],在200~400nrn内扫描不同时间的配伍液,显示吸收值无明显变化,吸收曲线未发生改变,也未见其他吸收峰产生。3讨论笔者在测定配伍液含量时,参考相关文献【],采用双波长紫外分光光度法,[link widoczny dla zalogowanych],以消除两者之间的相互干扰现象,结果较为满意。此方法原理简单,操作方便。但在选择组合波长时,须反复精选,因为等吸收波长选择正确与否。会直接影响测定结果。配伍体系中NS对测定无影响。表4盐酸洛美沙星与甲硝唑氯化钠注射液配伍后(37℃)盐酸洛美沙星、甲硝唑注射液的pH值分别为3.5~5.5[引、4.5~6.0t引,两者均为酸性,配伍液的pH值为(4.43±0.02),符合注射液的pH要求(4~9)。配伍液不会因pH值改变导致溶解度降低而产生沉淀现象,且热稳定性也较好l9]。在稳定性试验中,配伍液分别在室温、37℃恒温水浴中6h内,pH值、外观以及含量均无明显变化,因此,这两种药物在6h内可以配伍使用。笔者仅考察了洛美沙星与甲硝唑配伍的部分理化性质,[link widoczny dla zalogowanych],两者配伍应用时的药代动力学、药效动力学及其不良反应尚待进一步探讨。
