      Abstract

      The measurement of morphological descriptors is widely applied in the pharmaceutical industry to evaluate (intermediate) solid forms in terms of their critical quality attributes that influence product-handling in the manufacturing process or to allow a prediction of the performance of the final dosage form. Previous publications have demonstrated the use of micro-focused tomography to analyze formulations and relate the product performance to structure and sample homogeneity. The aim of this study was to assess the use of a commercial nano-focused x-ray tomography system to non-invasively investigate the three-dimensional structure of various solid pharmaceutical products. Special emphasis was given to sizing, the quantification of internal voids and the characterization of formulated samples.
