Defining Batches for Continuous Manufacturing Processes
规定连续生产工艺的批次
The definition of a batch has regulatory implications, particularly with respect to current good manufacturing practice (CGMP), product recalls, and regulatory decisions. The terms batch and lot are defined in the regulations (21 CFR 210.3) as follows:
批次的定义具有监管含义,特别是在CGMP、产品召回和监管决策方面。术语批次(batch)和批次(lot)在法规(21 CFR 210.3)中定义如下:
 Batch means a specific quantity of a drug or other material that is intended to have uniform character and quality, within specified limits, and is produced according to a single manufacturing order during the same cycle of manufacture.
 在规定的限度内,按照某一生产指令在同一生产周期内生产出来的,具有统一性质和质量的一定数量的药品或其它物料
 Lot means a batch, or a specific identified portion of a batch, having uniform character and quality within specified limits; or, in the case of a drug product produced by continuous process, it is a specific identified amount produced in a unit of time or quantity in a manner that assures its having uniform character and quality within specified limits.
 批次是指在规定范围内性质和质量一致的一批或一批中特定的均一部分;连续生产的药品,是指在一定的时间或者数量内,规定限度内具有均一的性质和质量的药品。
These definitions for both batch and lot are applicable to continuous manufacturing. A batch can be defined based on the production period, quantity of material processed, quantity of material produced or production variation (e.g., different lots of incoming raw material), and can be
6 flexible in size to meet variable market demands by leveraging the advantage of operating continuously over different periods of time. A lot may also be considered a sub-batch. The actual batch or lot size should be established prior to the initiation of each production run.
批次(batch)和批次(lot)这些定义适用于连续生产。批次(batch)可以根据生产周期、物料加工数量、生产的物料数量或生产变化(例如,不同批次的原料)来定义,并且可以通过不同时间段内连续生产的优势来灵活调整批量以满足不同的市场需求。批次(lot)也可被视为子批。应在每次生产运行开始之前确定实际批次(batch)或批次(lot)的批量。
For batches that are defined based on time (e.g., a production period), a connection between material traceability and batch must be established to identify the specific quantity of the drug (21 CFR 210.3).
基于时间(例如,生产周期)定义的批次,必须建立物料可追溯性和批次之间的联系以确定药品的具体数量(21 CFR 210.3)。 |
