Phase 3: Formulation Development

Phase 3: Formulation Development contains 5 topic pages in Pharmaceutics.

Formulation development is the stage at which the physicochemical dataset generated during preformulation is translated into an actual, manufacturable, stable, and effective dosage form. It encompasses the rational selection of excipients, the design and optimisation of a manufacturing process, and the systematic characterisation of the resulting product against a predefined set of Critical Quality Attributes. This chapter addresses formulation development across the major dosage form categories — solid, liquid, semi-solid, and parenteral — and introduces the Quality by Design paradigm that governs modern, risk-based formulation practice.
