Automated Tomographic Assessment of Structural Defects of Freeze-Dried Pharmaceuticals

AAPS PharmSciTech. 2024 Jun 25;25(6):143. doi: 10.1208/s12249-024-02833-7.

Abstract

The topology and surface characteristics of lyophilisates significantly impact the stability and reconstitutability of freeze-dried pharmaceuticals. Consequently, visual quality control of the product is imperative. However, this procedure is not only time-consuming and labor-intensive but also expensive and prone to errors. In this paper, we present an approach for fully automated, non-destructive inspection of freeze-dried pharmaceuticals, leveraging robotics, computed tomography, and machine learning.

Keywords: X-ray tomography; freeze-drying; lyopohilisate; non-destructive inspection.
