Multivariate data analysis to evaluate commonly used compression descriptors

Numerous studies elucidated material behavior based on compression analyses. Especially compressibility, compactibility and tabletability were in the focus of these investigations. In the present study, a comprehensive multivariate data analysis was performed using principal component analysis method. Twelve pharmaceutically used excipients were selected for direct compression tableting and subsequent evaluation of several compression analyses. Material properties, tablet properties, tableting parameters and parameters from compression analyses were used as input variables.

Highlights

• Principal component analysis was used for grouping of materials in tableting.

• Tabletability was shown to be the property of highest relevance in characterization.

• Rearrangement index of Kawakita analysis was found to correlate with tabletability.

• Compressibility descriptors were examined as having a minor importance.

• Three analyses were found to preferably use in characterizing a materials behavior.

The materials could successfully be grouped using principal component analysis. Of the tableting parameters, the compression pressure showed the greatest influence on the results. The tabletability was found to be the most important compression analysis in the material characterization. Compressibility and compactibility only played a minor role in the evaluation. Some important insights have been gained for a deeper understanding of the tableting process using the multivariate approach to evaluate the variety of compression data.

Excipients used in the study besides other: Flowlac, Granulac, Vivapur, Dicalcium Phosphate DI-CAFOS, Tablettose, Fujicalin
