摘 要
QbD 是质量源于设计(Quality by Design)的简称,是一种
科学的、基于风险的、全面的和先进的药品开发方法,强调通过
对产品属性和生产工艺的理解,通过设计和操纵来保证产品的质
量属性。
本文运用 QbD 理念,以某生产企业为例,详细阐述了 QbD 在
卡托普利片空白颗粒法工艺放大中的应用及作用。首先,依照产
品目标特性,确定了卡托普利片的关键质量属性,为标示量、溶
出度、卡托普利二硫化物、含量均匀度、硬度、脆碎度;其次,
针对该部分关键质量属性及空白颗粒法工艺放大的工艺与过程进
行分析、理解,并应用风险评估,确定了工艺放大的关键工艺参
数,为颗粒水分、制粒参数、整粒参数、混合参数;第三,通过
风险评估、实验设计、过程分析等技术手段和方法及现有知识,
详细讲明了关键质量属性及关键工艺参数间的函数关系,进而确
定了卡托普利片空白颗粒法工艺放大的设计空间与操纵策略。最
后,在设计空间内进行生产操作,关键质量属性指标均操纵在内
控标准范围内,经统计产品一次合格率等指标,确认利用 QbD 能
够改善和保证卡托普利片空白颗粒法工艺放大的效益及最终产品
的质量。

Application of QbD in the Process Scale Up of the
Blank Granulation Method in Captopril Tablet
Manufacturing to Enhance and Ensure the
Improvement of Efficiency and Final Product
Quality
Abstract
QbD, the abbreviattion for "Quality by Design", is a
scientific, risk-based holistic and proactive approach
to pharmaceutical product development, which emphasizes
on the understanding of product attributes and process
control, and ensuring the quality attributes of a
product through design and control.
This thesis, with the manufacturing of captopril
tablet as an exmaple, illustrated the application and
beneficial effect of QbD in the scale-up of the blank
granulation process.
First, based on the target product profile, the
Critical Quality Attributes of captopril tablet were
confirmed, i.e., dissolution, captopril disulfide,
content uniformity, strength, and friability. Second,
through the analysis and understanding of the Critical
Quality Attributes and the process for the scale-up of
the blank granulation method, the Critical Process
Parameters for the scale-up of the blank granulation
process of captopril were identified, i.e.,
moisture content of particles, and the prameters of
granulation and final mix. Third, through
applying risk evaluation, DOE, and PAT technologies and
methods, and other available knowledge and information,
the function of the Critical Quality Attributes and the
Critial Process Parameters was derived. In turn, the
design space of the scale-up of blank granulation
process was determined. Lastly, the manufacturing of
the product was conducted within the design
space. According to the statistics of first time pass
rate, all Critical Quality Attributes were within the
internal control specifications, demonstrating the
improvement of the scale-up efficiency and
the ensurence of the final product quality.
