Aims The aims of the study were to compare [14C]-paracetamol ([14C]-PARA) paediatric pharmacokinetics (PK) after administration mixed in a therapeutic dose or an isolated microdose and to develop further and validate accelerator mass spectrometry (AMS) bioanalysis in the 0-2 year old age group. Methods [14C]-PARA concentrations in 10-15 μl...

Immunogenicity is a major issue of concern for monoclonal antibodies used in human diseases and is by default mainly determined in non-human primates (NHP), as target molecules are considered most similar in NHP compared to human. In this manuscript the predictive value of immunogenicity testing in minipigs for human safety is evaluated, as the...

In contrast to primary hepatocytes, estimating carrier-mediated hepatic disposition by using a panel of single transfected cell-lines provides direct information on the contribution of the individual transporters to the net disposition. The most direct way to correct for differences in transporter abundance between cell-lines and tissue is by...

The metabolism and active transport of ritonavir and saquinavir were studied using sandwich-cultured rat hepatoyctes and rat liver microsomes. For ritonavir four comparable metabolites were observed in the sandwich-culture and in microsomes. For saquinavir eight metabolites were observed in sandwich-culture and 14 different metabolites in...

Background and objective: The dopamine agonist rotigotine has been formulated in a silicone-based transdermal system for once-daily administration. The objective of the present study was to characterise the mass balance of rotigotine in humans after administration of a single transdermal patch containing radiolabelled [14C]rotigotine and to...

An alternative approach is introduced in determining the in vitro intrinsic clearance of slowly metabolized compounds. The long-term sandwich rat hepatocyte culture was exploited, allowing for sufficient substrate depletion to obtain a reliable clearance estimation; in its physiology, it resembles the in vivo liver, thus allowing in vivo...

In this review we will focus on the current status and views concerning the production of antibody fragments and antibody fusion proteins by yeasts and filamentous fungi. We will focus on single-chain antibody fragment production (scFv and VHH) by these lower eukaryotes and the possible applications of these proteins. Also the coupling of...

The novel antidepressant mirtazapine is a racemate with both noradrenergic and serotonergic potentiating effects. In vitro metabolism of racemic mirtazapine was studied in (a) microsomes from cells expressing different cytochrome P450 (CYP) enzymes and (b) human liver microsomes from 10 subjects and compared with the rate of metabolism of 4...

The fibrin-specific thrombolyticum tissue-type plasminogen activator (t-PA) has proven to be a potent drug in several clinical trials, but its clinical application is complicated by the rapid clearance of t-PA from the circulation. The rapid plasma clearance of t-PA results from the uptake of t-PA in the liver. t-PA consists of several domains...

The influence of aging on the metabolism of antipyrine (AP) and hexobarbital enantiomers (R-HB and S-HB) with and without phenobarbital (PB) induction was investigated in a longitudinal study in rats aged 6, 12, 24 and 30 months. The metabolic clearances of AP (Cl(m AP)), R-HB (Cl(m R-HB)) and S-HB (Cl(m S-HB)) were used as indicators for P450...
