VALIDATION OF COMPENDIAL PROCEDURES
临江仙送钱穆父药典方法的验证
Test procedures for asssment of the quality levels of pharmaceutical articles are subject to various requirements. According to Section 501 of the Federal Food, Drug, and Cosmetic Act, assays and specifications in monographs of the United States Pharmacopeia and the National Formulary constitute legal standards. The Current Good Manufacturing Practice regulations [21 CFR 211.194(a)] require that test methods, which are ud for asssing compliance of pharmaceutical articles with established specifications, must meet proper standards of accuracy and reliability. Also, according to the regulations [21 CFR 211.194(a)(2)], urs of analytical methods described in USP NF are not required to validate the accuracy and reliability of the methods, but merely verify their suitability under actual conditions of u. Recognizing the legal status of USP and NF standards, it is esntial, therefore, that proposals for adoption of new or revid compendial analytical procedures be supported by sufficient laboratory data to document their validity.

用于评估药品质量的检验方法需要满足不同的要求。根据联邦食品，药品， 和化妆品法案501章，美国药典和国家处方专题论文里的试验和规范构成了法 律标准。CGMP法规ppt分享[21 CFR 211.194(a)]要求：用于评估药品满足已建立的规 范的检验方法必须满足准确、可靠、适当的标准。此外，根据法规21 CFR 211,194(a)(2)，USP-NF中叙述的分析方法的使用者不需要验证这些方法的准确 度和可信度，仅仅需要确认在实际使用条件下的适用性。考虑到USP和NF的 法律地位，采用新的或修改后的药典分析方法的建议，并且这个建议是由充分的 实验室数据支持以证明其有效，这是十分必要的。
The text of this information chapter harmonizes, to the extent possible, with the Tripartite International Conference on Harmonization (ICH) documents Validation of Analytical Procedures腹背运动 and the Methodology extension text, which are concerned with analytical procedures included as part of registration applications submitted within the EC, Japan, and the USA.
这一章节的内容尽可能地和ICH文献“分析方法的验证和方法学”（文献与包 含在EC,日本和美国递交的注册申请中的分析方法相关）协调一致。
SUBMISSIONS TO THE COMPENDIA
递交至药典
Submissions to the compendia for new or revid analytical procedures should contain sufficient information to enable members of the USP Council of Experts and its Expert Committees to evaluate the relative merit of propod procedures. In most cas, evaluations involve asssment of the clarity and completeness of the description of the analytical procedures, determination of the need for the procedures, and documentation that they have been appropriately validated. Information may vary depending upon the type of method involved. However, in most cas a submission will consist of the following ctions.
将新的或修改后的分析方法递交至药典，应包含足够的资料从而使得USP 委员会专家和其专家委员会能够评估拟定方法的价值。绝大多数情况下，评估包 括透明度的评估和分析方法叙述完整性的评估，确定方法需求，以及专家已经充 分验证的文件。涉及方法的类别改变，资料可能也会改变。然而，大部分情况下， 递交应包含如下的章节

Rationale—This ction should identify the need for the procedure and describe the capability of the specific procedure propod and why it is preferred over other types of determinations. For revid procedures, a comparison should be provided of limitations of the current compendial procedure and advantages offered by the propod procedure.
基本原理一此章节应确定方法的需求和叙述拟定的具体的方法的能力以及 它优于其它类别测定方法的原因。对于已修改的方法，需比较当前方法的局限性 和拟定方法的优点。
Propod Analytical Procedure—This ction should contain a complete description of the analytical procedure sufficiently detailed to enable persons “skilled in the art” to replicate it. The write-up should include all important operational parameters and specific instructions such as preparation of reagents, performance of system suitability tests, description of blanks ud, precautions, and explicit formulas for calculation of test results.

VALIDATION
验证
Validation of an analytical procedure is the process by which it is established, by laboratory studies, that the performance characteristics of the procedure meet the requirements for the intended analytical applications. Typical analytical performance characteristics that should be considered in the validation of the types of procedures desc
ribed in this document are listed in Table 1. Becau opinions may differ with respect to terminology and u, each of the performance characteristics is defined in the next ction of this chapter, along with a delineation of a typical method or methods by which it may be measured.
分析方法的验证是一个过程：通过实验室的研究确立了方法的性能参数可以 满足预期的分析应用的要求。本文件叙述的几种方法的验证需要考虑的典型的分 析性能参数列在表1中。因为对术语和使用的观点可能会有所不同，所以每个性 能参数在此章节的下部分给出定义，以及典型方法或能够测量的方法的描述。
The definitions refer to “test results.” The description of the analytical procedure should define what the test results for the procedure are. As noted in ISO 5725-1 and 3534-1, a test result is “the value of a characteristic obtained by carrying out a specified test method. The test method should specify that one or a number of individual measurements be made, and their average,or another appropriate function (such as the median or the standard deviation), be reported as the test result.

It may also require standard corrections to be applied, such as correction of gas volumes to standard temperature and pressure. Thus, a test result can be a result calculated from veral obrved values. In the simple ca, the test result is the obrved value itlf.” A test result also can be, but need not be, the final, reportable value that would be compare to the acceptance criteria of a specification. Validation of physical property methods may involve the asssment of the chemometric models. However, the typical analytical characteristics ud in method validation can be applied to the methods derived from the u of the chemometric models.
