6. Compression mechanics of pharmaceutical aggregates : Studies on the tabletting of spheronised aggregates with varying composition and porosity
Sammanfattning : The thesis investigated the tabletting behaviour of aggregates of different porosity and material composition, and focused on the role of the compression mechanics of the aggregates as a link between their structure and composition and the structure and functionality of tabletsformed from them. The aggregates studied all responded to compression by deformation and densification. LÄS MER
7. 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
8. Experimental and theoretical predictions of intestinal drug absorption
Sammanfattning : The subject of this thesis is the development of better experimental and computational predictions of the intestinal absorption properties of new drug candidates. In the last decade the drug discovery process has produced an increasing number of new drug candidates by the use of high throughput screening techniques. LÄS MER
9. Controlled Release Gel Formulations for Mucosal Drug Delivery
Sammanfattning : Drug delivery to nasal or ocular mucosa for either local or systemic action faces many obstacles – these routes are protected by effective mechanisms. Gel formulations with suitable rheological and mucoadhesive properties increase the contact time at the site of absorption. LÄS MER
10. Drug transport and metabolism in in vitro models of the human intestine : By Shamsi D. Raeissi
Sammanfattning : The objective of this thesis was to study the mechanisms of drug transport and metabolism in two different in vitro models of the human intestine: monolayers of human intestinal epithelial cell lines and intestinal microsomes. The first part of the thesis shows that Caco-2 cell monolayers are a good model for mechanistic studies of drug transport. LÄS MER
