Posaconazole is a second-generation triazole agent with a potent and broad antifungal activity. In addition to the oral suspension, a delayed-release tablet and intravenous formulation with improved pharmacokinetic properties have been introduced recently. Due to the large interindividual and intraindividual variation in bioavailability and drug-drug(More)
In critically ill patients, drug exposure may be influenced by altered drug distribution and clearance. Earlier studies showed that the variability in caspofungin exposure was high in intensive care unit (ICU) patients. The primary objective of this study was to determine if the standard dose of caspofungin resulted in adequate exposure in critically ill(More)
OBJECTIVE To assess the functional deficits in tapping performance of subjects with spastic hemiparesis. DESIGN In a pilot study, typing performance on a computer keyboard was examined on a number of performance measures. SETTING Department of Research and Development at the Werkenrode Institute. SUBJECTS Four subjects (mean age 16.4 years, standard(More)
Voriconazole is the agent of choice for the treatment of invasive aspergillosis in children at least 2 years of age. The galactomannan index is a routinely used diagnostic marker for invasive aspergillosis and can be useful for following the clinical response to antifungal treatment. The aim of this study was to develop a pharmacokinetic-pharmacodynamic(More)
Background: The estimated attributable mortality rate for invasive candidiasis (IC) in the Intensive Care Unit (ICU) setting varies from 30-40%. Physiological changes in critically ill patients may affect the distribution and elimination of micafungin and therefore dosing adjustments might be mandatory. Objective: To determine the pharmacokinetic parameters(More)

An important element in antimicrobial stewardship programmes is early switch from intravenous (i.v.) to oral antimicrobial treatment, especially for highly bioavailable drugs. The antifungal agent voriconazole is available both in i.v. and oral formulations and bioavailability is estimated to be >90% in healthy volunteers, making this drug a suitable(More)
BACKGROUND During an infection or inflammation, several drug-metabolizing enzymes in the liver are down-regulated, including cytochrome P450 iso-enzymes. Since voriconazole is extensively metabolized by cytochrome P450 iso-enzymes, the metabolism of voriconazole can be influenced during inflammation via reduced clearance of the drug, resulting in higher(More)
