Webinar: Digital Design of Drug Product

Application of global system analysis to a tablet manufacturing process

Traditionally, formulation and process development within the pharmaceutical industry is driven by extensive trial-and-error experimentation. The Digital Design of Drug Product (D3P) project integrates qualitative and quantitative tools to facilitate an approach to formulation and process design based on the development of fundamental process and product understanding. A global system analysis approach has been used to realise an in-silico ‘design space explorer.’ This tool is applied to a roller compaction tablet manufacturing process to understand the impact of raw material and process changes on product quality. The approach can be used to inform risk assessment and to design a robust control strategy for the product.

Topics covered

  • Introduction and D3P project overview
  • Case study - Application of GSA to a Tablet Manufacturing Process
