1. The Hepatobiliary Transport of Rosuvastatin In Vivo
Abstract : In vivo studies of hepatobiliary disposition are challenging. The hepatobiliary system is complex, as its physiological localization, complex cellular structure with numerous transporters and enzymes, and the interindividual variability in protein expression and biliary flow will all affect the in vivo disposition of a drug under investigation.

2. Involvement of Membrane Transport Proteins in Intestinal Absorption and Hepatic Disposition of Drugs Using Fexofenadine as a Model Drug
Abstract : The aims of this thesis were to study the in vivo relevance of membrane transporters for intestinal absorption and the hepatic disposition of drugs in humans and preclinical models. Fexofenadine is a substrate for ABCB1 (P-glycoprotein) and members of the organic anion transporting polypeptide (OATP/SLCO) family. READ MORE

3. ATP-Binding-Cassette Transporters in Biliary Efflux and Drug-Induced Liver Injury
Abstract : Membrane transport proteins are known to influence the absorption, distribution, metabolism, excretion and toxicity (ADMET) of drugs. At the onset of this thesis work, only a few structure-activity models, in general describing P-glycoprotein (Pgp/ABCB1) interactions, were developed using small datasets with little structural diversity.

4. Intestinal Permeability and Presystemic Extraction of Fexofenadine and R/S-verapamil
Abstract : The main objective of this thesis was to investigate the in vivo relevance of membrane transporters and cytochrome P450 (CYP) 3A4-mediated metabolism in the intestine and liver for the bioavailability of drugs in humans after oral administration.In the first part of the thesis, the main transport mechanisms involved in the intestinal absorption and bioavailability were investigated for fexofenadine, a minimally metabolized drug, which is a substrate for P-glycoprotein (P-gp) and members of organic anion transporting polypeptide (OATP) family.

5. Biopharmaceutical Evaluation of Intra-arterial Drug-Delivery Systems for Liver Cancer : Investigations in healthy pigs and liver cancer patients
Abstract : There are currently two types of intra-arterial drug-delivery system (DDS) in clinical use in the palliative treatment of primary liver cancer. The chemotherapeutic drug doxorubicin (DOX) can be formulated into a drug-in-lipiodol emulsion (LIPDOX) or a microparticulate drug-eluting bead system (DEBDOX). READ MORE
