ABSTRACT
Two dimensional liquid chromatography (2D-LC) has become an important way to achieve the separation of complex samples due to higher peak capacity, higher selectivity and better separation ability compared with one-dimensional liquid chromatography(1D-LC). 2D-LC has been developing rapidly in many fields, such as medicine, food, metabolites in vivo or in vitro and so on. This review illustrates various separation modes of 2D-LC and its applications and developments, with emphases on the research of quality control of drugs.
ABSTRACT
OBJECTIVE:To emphasis the importance to unceasingly upgrading of drug quality standard for drug quality and to arouse the attention of the related enterprises, medical institutions and governmental department to this matter. METHODS: The correlation between quality standard and drug quality was expounded systematically by citing examples and reviewing the pertinent literature, and the current status of drug quality standard in China was analyzed briefly. RESULT & CONCLUSION: Great importance should be attached to the evaluation of drug quality standard to improve drug quality standard level step by step and to ensure efficacy and safety of drugs.
ABSTRACT
OBJECTIVE:To evaluate the merits and demerits of automatic oral drug dispensing mode as compared with traditional dispensing mode.METHODS:The medication data in our hospital after adoption of single dose administration system were collected and summarized analytically in respect of drug quality management.RESULTS:The automatic oral drug dispensing mode is superior to traditional dispensing mode.CONCLUSION:Under single dose administration system,the application of automatic oral drug dispensing mode is conductive to the improving of pharmaceutical care level.However,the problems existing in its clinical use remain to be further studied.
