Quality by Design (QbD)
What is Quality by Design (QbD)?
Quality by Design (QbD) is a strategic approach executed in various industries, including pharmaceuticals, manufacturing, and product development, to ensure the consistent delivery of high-quality products. It involves a systematic process of integrating quality considerations throughout the entire product lifecycle, from conception to production.
Why is Quality by Design (QbD) important in pharma?
Quality by Design (QbD) ensures that drugs are consistently manufactured with optimal safety, efficacy, and overall quality by focusing on critical quality attributes (CQAs) and critical process parameters (CPPs). By identifying potential risks and implementing control strategies during the design phase, QbD helps in managing and mitigating risks associated with drug development and manufacturing. Quality by Design (QbD) also allows greater flexibility in manufacturing processes with the impact of variations and having control strategies, manufacturers can adapt to changes without compromising product quality.
What are the key features of QbD in pharma?
The key features of Quality by Design (QbD) include:
Target Product Quality Profile (TPQP) is a detailed description of the quality characteristics that the drug product should possess to ensure desired quality, safety, and efficacy.
Critical Quality Attributes (CQAs) are the physical, chemical, biological, or microbiological properties that are controlled to ensure the product meets its TPQP.
Regularly assessing and improving processes, manufacturers can enhance product quality and operational efficiency over time.
A control strategy is a planned set of controls derived from current product and process understanding. It ensures that the process consistently produces a product of desired quality.
