This episode provides a broad overview of the fascinating and complex journey a drug takes from initial lab discovery to large-scale industrial manufacturing. We'll discuss the fundamental differences between creating milligram quantities of a new chemical entity (NCE) in a research setting versus producing kilograms or even tons in a factory. The discussion will cover the vital role of "Process Chemistry". Key concepts like yield, purity, and safety will be explained, emphasizing how they become increasingly critical as production scales up.

We will explore the core manufacturing principles involved, highlighting the shift from scientific discovery to a blend of science and engineering. The challenges and hurdles of scaling up will be illustrated with real-world examples. Some examples cover, switching solvents, fine tuning every step, telescoping, and safety. The conversation underscores that it's not simply about "making more" but about fundamentally adapting the chemical process to work efficiently and safely at a much larger scale, all while adhering to stringent regulatory requirements.
