RESUMEN

OBJECTIVE:To study the main aspects of quality control of dexamethasone liposomes.METHODS:The structure of liposomes was studied with negative staining method of TEM.K-ratio spectrophotometry was wsed to determine the contert,and the Macrosep was wsed to seperate the entrapped from free drugs.RESULTS:An excellent linear relationship was obtained with the range of 4~52μg/ml,the average recovery percent was between 98.28%~99.71%.The entrapment efficiency was one of the important parameters of liposomes quality control.It was related with the clinical effect directly,the entrapment efficiency was more than 80%.CONCLUSION:This method is accurate,quick and reproducible.
