Pharmaceutical Development
Provides guidance on the contents of the pharmaceutical development section of a marketing application and introduces Quality by Design (QbD) concepts including Critical Quality Attributes, Critical Process Parameters, and Design Space.
Drug product development across all dosage forms. Primary audience is development scientists and regulatory affairs for submission preparation. Commercial manufacturing teams implement the design space.
- 01Identification and justification of Critical Quality Attributes (CQAs)
- 02Risk-based identification of Critical Process Parameters (CPPs) from QbD studies
- 03Design space definition — multidimensional combinations of inputs within which quality is assured
- 04Control strategy linking CQAs and CPPs to manufacturing controls
R2 issued August 2009 — no revisions since. Core QbD concepts remain current; FDA Process Validation (2011) built upon the Q8 foundation.
