This test is provided to determine pliance with the dissolution requirements where stated in the individual monograph for dosage forms administered orally. In this general chapter, a dosage unit is defined as 1 tablet or 1 capsule or the amount specified.Of the types of apparatus designs described herein, u the one specified in the individual monograph. Where the label states that an article is enteric coated and a dissolution or disintegration test does not specifically state that it is to be applied t
o delayed-relea articles and is included in the individual monograph, the procedure and interpretation given for Delayed-Relea Dosage Forms are applied, unless otherwi specified in the individual monograph.

青岛雅思培训本测试用于检测药品口服制剂的溶出度是否符合各论中的规定。本章中，除另有规定外，单位制剂定义为1片或1粒胶囊。对于本章中所述多种仪器，使用各论中规定的种类。除各论中另有规定外，如果检品是肠溶衣片且各论中的溶出度或崩解时限检查项下没有特别指出适用迟释剂的，使用本章中适用于迟释剂的流程和解释。ask的过去式
FOR DOSAGE FORMS CONTAINING OR COATED WITH GELATIN涂有或包含明胶的剂型
If the dosage form containing gelatin does not meet the criteria in the appropriate Acceptance Table(e Interpretation,Immediate-Relea Dosage Forms,Extended-Relea Dosage Forms, or Delayed-Relea Dosage Forms) becau of evidence of the prence of cross-linking, the dissolution procedure should be repeated with the addition of enzymes to the medium, as described below, and the dissolution results should be evaluated starting at the first stage of the appropriate Acceptance Table. It is not necessary to continue testing through the last stage (up to 24 units) when criteria are not met during the first stage testing, and evidence of cross-linking is obrved.
如果剂型中含有明胶，其不符合验收表中的标准（见判断，速释制剂，延释制剂，缓释制剂），因为存在明胶交联结合作用，它的溶解过程与外加的媒介酶是重复的，见下面的描述，并且溶解结果可以通过适当的验收表的开始的第一阶段标准进行评估。如果溶出结果不满足第一阶段的测试标准，那么就没有必要继续测试到最后阶段，并且也证明了明胶交联结合作用的存在。
Gelatin, in the prence of certain pounds and/or in certain storage conditions, including but not restricted to high humidity and temperature, may prent cross-linking. A pellicle may form on the external and/or internal surface of the gelatin capsule shell or on the dosage form that prevents the drug from being relead during dissolution testing (e more information in Capsules—Dissolution Testing and Related Quality Attributes<1094>).考研复试英语听力
明胶，存在于某一处方和/或某一储存条件下，如：高温高湿，可能存在明胶交联结合作用。在胶囊壳或其他剂型的外表面和/或表面形成一层膜阻止溶出试验过程中药物的释放（见胶囊-溶出度检测和相关质量属性<1094>）。

If the dissolution medium contains surfactant or other ingredients that are known to denature the enzyme ud, a pretreatment step in the dissolution testing of the dosage form may be applied. This pretreatment step is done using the specified dissolution
medium without the surfactant or the ingredient and with the addition of the appropriate amount of en
zyme according to the medium pH. The amount of enzyme added is appropriate to the volume of dissolution medium ud in the pretreatment. To achieve the specified medium volume for the final dissolution testing, the pretreatment step may be conducted with a smaller volume of medium without the ingredient such that the final volume is obtained when the ingredient is added at the end of the pretreatment step. All of the other conditions of the test (apparatus, rotation, or flow rate) should remain as described in the method or monograph. Typically, the duration of the pretreatment step is NMT 15 min. The required pretreatment time should be evaluated on a ca-by-ca basis and should be scientifically justified. This time should be included in the total time of the test. As an example, if the total time of the test is 45 min and 15 min are ud in the pretreatment step, the test will continue for 30 min after the addition of the ingredient.
如果溶出介质中添加了表面活性剂或其他已知成分的变性酶，那么此溶出实验就要把预处理步骤考虑进去。预处理过程就是是根据溶出介质的pH来确定加入酶的量，此处的溶出介质不含有表面活性剂和原料。酶加入的量要适合预处理所用的溶出介质的体积。为了达到最终溶出试验所需要的特定的溶出介质的体积，预处理阶段所用的溶出介质（不含原料）的体积要稍微小点，如此在预处理最后阶段加入原料的时候方可获得最终的溶出介质体积。其他所有的测试条件（如：设备、转速、流速）应该与方法或专论中描述的一致。通常预处理阶段的持续时间为NMT 15 min。所需的预处理时间应该根据具体案例具体分析，且应该科学、
