系数倍率法测定地塞米松滴眼液的含量刘金来（浙江省温州市第三人民医院温州３２５０００）摘要用系数倍率法不经关键词系数倍率法，地塞米松磷酸钠，羟苯乙酯，滴眼液地塞米松滴眼液含地塞米松磷酸钠（简称Ｄ）和羟苯乙酯（简称Ｎ）。不少地方（河南、辽宁等）药品标准均...

examethasone phosphate sodium in eye drops was determined directly by K ratio spectrophotometry at 242nm and 255.5 nm without separation.This method could eliminate the interference of ethylparaben.The average recovery and the coefficients of variation were 99.5% and 0.37% ,respectively.
