Chapter <1092> address the development andvalidation of dissolution procedures, with a focus on solid oral dosage forms.Many of the concepts prented, however, may be applicable to other dosageforms and routes of administration. General recommendations are given with theunderstanding that modifications of the apparatus and procedures as given in USPgeneral chapters need to be justified.

1. PRELIMINARYASSESSMENT (FOR EARLY STAGES OF PRODUCT DEVELOPMENT/DISSOLUTION METHODDEVELOPMENT)
1. 前期评估（产品开发/溶出度方法开发的初期阶段）
Beforemethod development can begin, it is important to characterize the molecule sothat the filter, medium, volume of medium, and apparatus can be chon properlyin order to evaluate the performance of the dosage form.
在开始溶出方法开发之前，我们对用以评价制剂溶出行为的滤膜、溶出介质、溶出介质体积和溶出设备进行适当的筛选是非常重要的。
1.1 Performing Filter Compatibility
1.1 滤膜相容性研究
Filtrationis a key sample-preparation step in achieving accurate test results. Thepurpo 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 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行过滤。
Filtration also removes insolubleexcipients that may otherwi interfere with the analytical finish. Selectionof the proper filter material is important and should be accomplished, andexperimentally justified, early in the development of the dissolutionprocedure. Important char对肾好的食物有哪些
acteristics to consider when choosing a filtermaterial are type, filter size, and pore size. The filter that is lectedbad on evaluation during the early stages of dis
solution procedure developmentmay need to be reconsidered at a later time point. Requalification has to beconsidered after a change in composition of the drug product or changes in thequality of the ingredients (e.g. particle size of microcrystalline cellulo).
