13、 accurate test results. Thepurpose of filtration is to remove undissolved drug and excipients from thewithdrawn solution. If not removed from the sample solution, particles of thedrug will continue to dissolve and can bias the results. Therefore, filteringthe dissolution samples is usually necessary
14、 and should be done immediately ifthe filter is not positioned on the cannula.为获得准确试验结果，过滤是样品制备的一个关键步骤。过滤的目的是为了除去溶出液中未溶解的药物和辅料。如果不把未溶解的药物和辅料从样品溶液中除去，那么未溶解的药物颗粒将会继续溶解使试验结果出现偏差，因此，如果取样管中没有过滤器，应立即对溶出度样品进展过滤。Filtration also removes insolubleexcipients that may otherwise interfere with the analytical fin
15、ish. Selectionof the proper filter material is important and should be accomplished, andexperimentally justified, early in the development of the dissolutionprocedure. Important characteristics to consider when choosing a filtermaterial are type, filter size, and pore size. The filter that is selectedbased on evaluation during the early stages of dissolution procedure developmentmay need to be reconsidered at a later time point. Requalification has to beconsidered after a change in composition of the drug prod
