: This study aimed to establish a predictive model for critical quality attributes (CQAs) related to tablet integrity, including tablet breaking force (TBF), friability, and capping occurrence, using machine learning-based models and nondestructive experimental data. : The machine learning-based models were trained on data to predict the CQAs of metformin HCl (MF)-containing tablets using a commercial-scale wet granulation process, and five models were each compared for regression and classification. We identified eight input variables associated with the process and material parameters that control the tableting outcome using feature importance analysis.

Article Synopsis
  • The study investigates the ejection pressure of bilayer tablets (BLTs) made of metformin HCl and evogliptin tartrate, looking into how internal cracks affect this pressure and the tablet’s structure.
  • Results show that as ejection pressure increases with compaction, it sharply decreases after reaching a certain point, indicating a complex relationship between pressure and internal integrity.
  • Finite element method (FEM) simulations confirm that internal cracks weaken the tablet's structure, leading to potential delamination during ejection, emphasizing the importance of measuring ejection pressure to avoid damaging cracks.
