Abstract:
OBJECTIVE To study the preparation of compound berberine hydrosulphate clyster,and determine its quantitative and stability. METHODS To organize prescription according to disease and the supplementary materials dose were found with orthogonal experiment. RESULTS The preparation was stable,reasonable,effective,and can be determined easily. CONCLUSION The clyster was dramatically effective,direct and little side-effects.

Abstract:
OBJECTIVE To study the prepartion of ketoprofen gel and its in vitro release. METHODS PVA and glycerin was used as carriers. RESULTS KFP was delivered at zero order.The higher the drug content,the faster the delivery speed.5% urea had no effect on KFP transdermal delivery.At a content of more than 10%,urea could significantly accelerate KFP transdermal delivery. CONCLUSION Gel was stable and accorded the clinical demands.

Abstract:
OBJECTIVE To determine phenacetin and caffeine in compound acetylsalicylic acid tablets. METHODS Multiple regression spectrophotometry was adopted as follow:The sample is dissolved in ethanol,add solution of 02mol/L NaOH to hydrolysis acetylsalicylic acid,the components are determined in phosphate salt buffet (pH 6.5). RESULTS The average recoveries for phenacetin and caffeine were 99.8% and 99.9%,with RSD 0.72% and 0.52%,respectively. CONCLUSION Accuracy of the method was compared with official quantitative analysis and no significant difference was found.

Abstract:
OBJECTIVE To simultaneous determine the main-component dexamethasone sodium phosphate and the interfering-component ethylparaben in compound dexamethasone sodium phosphate eye drops without separation. METHODS A convolution spectrometry method has been applied. RESULTS The average recoveris and relative standard deviation were 100.8%,10%;9939%,061%,respectively. CONCLUSION This method is convenient,accuracy and suitable for routine analysis of multicomponent preparation which has interference in ultraviolet spectrum.

Abstract:
OBJECTIVE To determine ofloxacin and hydroctisone in compound ofloxacin ear drops without separation. METHODS The convolution spectrometry method was used. RESULTS The average recovery and RSD of ofloxacin and hydrocortisone acetate were as 100.24%,0.68%;100.09%,0.61%. CONCLUSION The method is convient,accuracy and suitable for the determination of ear drops.
