Quality means fitness for intended use. Pharmaceutical quality refers to product free of contamination and reproducibly delivers the therapeutic benefit promised in the label to the consumer. The Quality of the pharmaceutical product can be evaluated by in vivo or in vitro performance tests. Quality by design assures in vitro product performance and In vitro product performance provides assurance of in vivo product performance.
“Hence Quality by design relate to Product Performance”. DefinitionThe pharmaceutical Quality by Design (QbD) is a systematic approach to development that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management. Quality by Design (QbD) is emerging to enhance the assurance of safe, effective drug supply to the consumer, and also offers promise to significantly improve manufacturing quality performance. QbD development process include:. Begin with a target product profile that describes the use, safety and efficacy of the product. Define a target product quality profile that will be used by formulators and process engineers as a quantitative surrogate for aspects of clinical safety and efficacy during product development. Gather relevant prior knowledge about the drug substance, potential excipients and process operations into a knowledge space.
Use risk assessment to prioritize knowledge gaps for further investigation. Design a formulation and identify the critical material (quality) attributes of the final product that must be controlled to meet the target product quality profile. Design a manufacturing process to produce a final product having these critical material attributes. Identify the critical process parameters and input (raw) material attributes that must be controlled to achieve these critical material attributes of the final product. Use risk assessment to prioritize process parameters and material attributes for experimental verification. Combine prior knowledge with experiments to establish a design space or other representation of process understanding. Establish a control strategy for the entire process that may include input material controls, process controls and monitors, design spaces around individual or multiple unit operations, and/or final product tests.

The control strategy should encompass expected changes in scale and can be guided by a risk assessment. Continually monitor and update the process to assure consistent quality.Design of experiments (DOE), risk assessment, and process analytical technology (PAT) are tools that may be used in the QbD process when appropriate.
