1. The Hepatobiliary Transport of Rosuvastatin In Vivo
Sammanfattning : 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
Sammanfattning : 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. LÄS MER
3. Intestinal Permeability and Presystemic Extraction of Fexofenadine and R/S-verapamil
Sammanfattning : 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.
