Quality by design (QbD) approaches in current pharmaceutical set-up

Area of Science:

• Pharmaceutical Science
• Chemical Engineering
• Regulatory Science

Background:

• Quality by Design (QbD) is promoted by regulatory bodies like the FDA and ICH to address rising development costs and innovation barriers.
• QbD principles integrate risk management and science-based manufacturing to ensure product quality and process understanding.
• The pharmaceutical industry is increasingly adopting QbD for developing safe and effective products.

Purpose of the Study:

• To review the core elements, design principles, and tools associated with Quality by Design (QbD).
• To explore the diverse applications of QbD across pharmaceutical development, including dosage form and method development.
• To highlight QbD's role in meeting evolving regulatory requirements.

Main Methods:

• Review of QbD elements, design strategies, and associated tools.
• Analysis of QbD applications in pharmaceutical product and process development.
• Discussion of QbD's contribution to regulatory compliance.

Main Results:

• QbD facilitates process understanding through variation identification and management.
• Design space enables prediction of product quality attributes.
• Successful implementation of QbD principles leads to improved product quality and manufacturing efficiency.

Conclusions:

• QbD adoption is progressing within the pharmaceutical industry for enhanced product quality and safety.
• Continued experience and metric gathering are necessary to fully demonstrate QbD benefits to all stakeholders.
• Understanding QbD principles is crucial for optimizing complex drug delivery systems in the future.
