ABSTRACT
Objective To investigate and analyze the usage of expensive outpatient prescriptions in different hospitals in Longgang area,Shenzhen,and to discuss and provide reference for the rational usage of expensive pre-scriptions.Methods Two primary hospitals,two secondary hospitals and one tertiary hospital in the Longgang area, Shenzhen,were chosen as the research targets.The expensive outpatient prescriptions,defined as the amount of pre-scription was over 150,200 and 300 yuan for primary,secondary and tertiary hospital respectively,were randomly selected and evaluated using international standards for the rational use of drugs.Results The average prescription items for primary,secondary and tertiary hospitals were 2.96,2.61 and 2.61.The largest proportions of prescription costs were 150 to 200 yuan,200 to 250 yuan and 300 to 350 yuan,which were respectively accounted for 49.6%, 56.6% and 37.7%.The frequency of using proprietary Chinese medicine,was 60.08%,68.18% and 41.62%respectively,which was not reasonable.The clinical diagnosis for the prescriptions of primary and secondary hospitals was mainly composed of trauma,bronchitis and vaginitis.The usage of drugs was not reasonable about the use of anti-biotics and infusion.In addition,the clinical diagnosis for the prescription of tertiary hospital was mainly diabetes, hypertension and cerebral infarction,where the abuse of using large dose of adjuvant drug was observed.Conclusion The frequency of using proprietary Chinese medicine is higher at all levels of hospital.In order to reduce the propor-tion of expensive prescription,the medicine institution should establish a sound system for drug use management and strengthen supervision and verification for western medicine physicians using proprietary Chinese medicine in their prescription.Furthermore,we should intervene and restrict the abuse usage of the adjuvant medicine.
ABSTRACT
[Objective] To establish a content determination method of Berberine hydrochloride in San Yu Ointment by HPLC.[Methods] RP-HPLC was performed to determine Berberine hydrochloride on a column of Agilent Zorbax Eclipse XDB-C8(4.6?150mm,5?m)at 20℃; Acetonitrile-0.1 % H3PO4 (50∶50)(Adding 0.1 g C12H25NaO4S to every 100 mL)was used as mobile phase,the flow rate was 1.0 mL?min-1.The detection wavelength was at 265 nm.[Results]A good linearity can be found in the range of 39.40 ~394.0 ng,and the regression equation was Y = 4.073?103x+2.248 ? 103 (r=0.9992).The recovery was between 97.9 %~100.9 %,and the average recovery rate was 99.4 %,RSD was 1.5 %.[Conclusion]The method is simple,rapid,accurate and available,which can be used to control the quality of San Yu Ointment.
ABSTRACT
OBJECTIVE:To consummate the quality control criteria of Lemai granule.METHODS:Qualitation identifica?tion of Radix paeoniae rubra and nutgrass galingale rhizome in Lemai granule were performed by TLC,and the content of tanshinol-the chief component in Radix Salviae miltiorrhizae was determined by HPLC.RESULTS:The results showed that the color spectrum identification of Radix paeoniae rubra and nutgrass galingale rhizome in Lemai granule were positive.Good linear relationship was achieved between tanshinol sodium and peak area when the concentration range of which was0.203?g～2.030?g(r=0.9998).The average recovery rate was98.93%(RSD=1.04%).CONCLUSION:The established method in this research can be used as the quality control for Lemai granule.
