PURPOSE A case example is presented in which the physiologically based modeling approach has been used to model the absorption of a lipophilic BCS Class II compound predominantly metabolized by CYP3A4, and to assess the interplay of absorption related parameters with the drug-drug interaction (DDI) potential. METHODS The PBPK model was built in the rat(More)
The selectin-mediated rolling of leukocytes along the endothelial cells is a prerequisite step followed by firm adhesion and extravasation into the inflamed tissue. This initial contact can be suppressed by sulphated polysaccharides. We have studied the effect of sulphated polysaccharides on the ultimate polymorphonuclear leukocyte (PMN) recruitment and(More)
To evaluate the role of interleukin-8 (IL-8) on the activation of neutrophils in rheumatoid arthritis (RA), we measured IL-8 and the adhesion molecules, L-selectin (CD62L), CD11b and CD18, on neutrophils in paired peripheral blood and synovial fluid of RA patients. Synovial fluid IL-8 levels were significantly increased compared to peripheral blood.(More)
Rolling of neutrophils in postcapillary venules is believed to be an obligatory step in the adhesion of neutrophils to endothelial cells, preceding firm attachment and emigration. This rolling on the endothelial surface can be blocked by sulphated polysaccharides. Therefore, dextran sulphate or dextran T500 was injected intravenously (i.v., 25 mg/kg) and(More)
