1. Particle interactions and internal tablet structure : Factors affecting the mechanical strength of pharmaceutical compacts
Sammanfattning : A simple tablet model was utilised to identify parameters responsible for tablet compactibility. In this model tablets were considered as homogeneous and isotropic aggregates of individual spherical particles. If the particles were located close enough to each other, interparticulate bonds were assumed to be developed. LÄS MER
2. Multivariate methods in tablet formulation
Sammanfattning : This thesis describes the application of multivariate methods in a novel approach to the formulation of tablets for direct compression. It begins with a brief historical review, followed by a basic introduction to key aspects of tablet formulation and multivariate data analysis. LÄS MER
3. Tableting performance of dry granulated particles : Significance and assessment of compression mechanical properties
Sammanfattning : Dry granulation (DG) is often utilized as an intermediate process during tablet manufacturing, for improving flow characteristics of the powder blend and/or reducing segregation issues related to the active pharmaceutical ingredient (API). The resulting granules exhibit typically irregular shapes with rough surfaces and their mechanical properties are related to the feeding powder and the process parameters used during the DG. LÄS MER
4. Flow and Compression of Granulated Powders : The Accuracy of Discrete Element Simulations and Assessment of Tablet Microstructure
Sammanfattning : Simulations are powerful and important tools for gaining insight into powder processes. Ultimately, simulations have the potential to replace experiments. Thus, accurate models and insight into the essential factors for descriptions of powder behaviour are required. LÄS MER
5. Identification and Variation of some Functionality Related Characteristics of Pharmaceutically Relevant Solid Materials and their Effect on Product Performance
Sammanfattning : The aim of this thesis was to identify some functionality related characteristics of pharmaceutically relevant solid materials and to study the effect of their variation on processing behaviour and product performance. For this purpose, particles with different characteristics were prepared under a variety of conditions by crystal agglomeration, wet granulation and spray drying. LÄS MER
