摘要
目的 :建立高效液相色谱法测定美罗培南的含量 ;考察注射用美罗培南与5 %GS、GNS、NS注射液配伍的稳定性。方法 :色谱柱 :Nova -PakC18 柱 ;流动相 :乙腈 -0 05molKH2PO4(4∶96) ;流速 :1 0ml/min ;检测波长 :300nm。取美罗培南加入5 %GS、GNS、NS注射液中 ,在常温条件下观察配伍液的外观变化 ,用HPLC法测定配伍后不同时间美罗培南的浓度 ,同时测定配伍液的pH及不溶性微粒变化。结果 :在12 5～250μg/ml范围内 ,峰面积与浓度呈现良好的线性关系 (r=0 9999) ,平均回收率为99 7 % ,RSD为1 1 %。结论 :本法高效、快速、准确 ;美罗培南在5 %GS、GNS。
OBJECTIVE:To establish a HPLC method for determining the content of Meropenem and to observe the stability of Meropenem in mixing with 5%GS,GNS and NS.METHODS:The conditions of HPLC were:column,Nova-Pak C18;mobile phase,acetonitrile-0.05mol KH2PO4(4∶96);flow rate,1.0ml/min;detection wavelength,300nm.After Meropenem mixing with 5%GS,GNS and NS,the changes of external apperance were observed in room temperature,the content was detected with HPLC and the pH and insoluble particles were determined.RESULTS:The calibration curve was in good linearity in the range of 12.5～250μg/ml(r=0.9 999)and the recovery was 99.7% with RSD=1.1%.CONCLUSION:This detection method is effective,rapid and accurate.Meropenem is stable in infusion fluids for 4 hr.
