INTRODUCTION

前言

Purpose

目的

The Dissolution Procedure: Developmentand Validation <1092> provides a comprehensive approach covering items to considerfor developing and validating dissolution procedures and the accompanyinganalytical procedures. It addresses the use of automation throughout the testand provides guidance and criteria for validation. It also addresses thetreatment of the data generated and the interpretation of acceptance criteriafor immediate- and modified-release solid oral dosage forms.

溶出实验:开发和验证（1092）指导原则提供了在溶出度方法开发和验证过程中以及采用相应分析方法时需要考虑的因素。本指导原则贯穿溶出度实验的全部过程，并对方法提供了指导和验证标准。同时它还涉及对普通制剂和缓释制剂所生成的数据和接受标准进行说明。

Scope

范围

Chapter <1092> addresses the development andvalidation of dissolution procedures, with a focus on solid oral dosage forms.Many of the concepts presented, 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 USP general chapters need to be justified.

<1092>章节讨论了溶出度实验的开发和验证，重点是口服固体制剂。所提出的许多概念也可能适用于其他剂型和给药途径。关于设备和方法的修改部分在USP通则中给出了合理的说明。

The organization of <1092> follows the sequence of actions often performed inthe development and validation of a dissolution test. The sections appear inthe following sequence.

2.6 Dissolution Procedure Assessment

2.6溶出方法评估

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 chosen 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. 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 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。
