81 – Crystallization and Solid Form Selection (S6E6)
From Concept to Medicine - A Comprehensive Drug Development Journey
This episode delves into the critical importance of crystallization in defining a drug's solid-state properties and its impact on overall performance. The conversation centers on polymorphism – the ability of a drug substance to exist in multiple crystal forms – and how these different forms can have vastly different properties, such as solubility, stability, and bioavailability.
We'll explore how scientists carefully control the crystallization process to obtain the desired polymorph with optimal characteristics. The dialogue will highlight the implications of solid-state properties on drug formulation, manufacturing, and shelf life. Real-world examples from OPR&D and other sources will illustrate the challenges and strategies involved in selecting and controlling the solid form of a drug substance.
