ABSTRACT
OBJECTIVE:To discuss rational use of injection in order to provide reference for rational use of injection in the clinic. METHODS:Drug use was analyzed in respect of route of administration,selection of solvent,compatibility of drugs, speed of intravenous administration,the concentration of mixture,etc. RESULTS&CONCLUSION:There are some mistakes in the application of injections,but some faults and adverse drug reactions (ADRs) can be warned early. By strengthening pharmaceutical monitoring,related faults and ADRs can be reduced to the minimum.
ABSTRACT
OBJECTIVE:To establish a method for simultaneous determination of the effective constituents rhein,emodin and chrysophanol in jiangzhiyin by HPLC.METHODS:SHIMADU VP-ODS column was used as analytical column,methanol-0.2%phosphoric acid(80∶20)as mobile phase,the flow rate was set at1ml/min,the detection wavelength at225nm,column temperature at room temperature.RESULTS:The linear ranges of detected rhein,emodin and chrysophanol in jiangzhiyin were0.015～0.15?g(r=0.9996),0.014～0.14?g(r=0.9998)and0.0085～0.085?g(r=0.9993)respectively;The average recoveries were99.26%(RSD=2.00%),98.72%(RSD=1.80%)and99.76%(RSD=2.3%)respectively.CONCLUSION:The determination results are stable and accurate,and the method is feasible and reliable,which can be used for the quality control of jiangzhiyin.
