PDA Technical Glossary

PDA Technical Reports are highly valued membership benefits because they offer expert guidance and opinions on important scientific and regulatory topics and are used as essential references by industry and regulatory authorities around the world. These reports include terms which explain the material and enhance the reader’s understanding.

The database presented here includes the glossary terms from all current technical reports. The database is searchable by keyword, topic, or by technical report. Each definition provided includes a link to the source technical report within the  PDA Technical Report Portal.

Process Qualification
Documented verification that a system is capable of consistently performing or controlling the activities of the processes it is required to perform or control, according to written and preapproved specifications, while operating in its specified operating environment. (TR3) Confirming that the manufacturing process as designed is capable of reproducible commercial manufacturing. (TR54) (TR60) (TR54-5)

Process Validation
The documented evidence that the process, operated within established parameters, can perform effectively and reproducibly to produce an intermediate or API (drug substance) meeting its predetermined specifications and quality attributes. (TR14) (TR42) Establishing documented evidence which provides a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes. (TR44) The collection and evaluation of data, from the process design stage through commercial production, which establishes scientific evidence that a process is capable of consistently delivering quality products. (TR54) (TR57) (TR74) The collection and evaluation of data, from the pro­cess design stage through commercial production, which establishes scientific evidence that a process is capable of consistently delivering quality product. The documented evidence that the process, op­erated within established parameters, can per­form effectively and reproducibly to produce a medicinal product meeting its predetermined specifications and quality attributes, as described in EMA, EU GMP, Part 1, Annex 15, drug/me­dicinal product. (TR56) EMA: The documented evidence that the process, op­erated within established parameters, can per­form effectively and reproducibly to produce a medicinal product meeting its predetermined specifications and quality attributes. US FDA: The collection and evaluation of data, from the process design stage through commercial pro­duction, which establishes scientific evidence that a process is capable of consistently deliver­ing quality products. (TR60-2) The documented evidence that the process, operated within established parameters, can perform effectively and reproducibly to produce an intermediate or drug substance meeting its predetermined specifications and quality attributes (1, 17).
