Population Pharmacokinetics of Levetiracetam in Patients with Traumatic Brain Injury and Subarachnoid Hemorrhage Exhibiting Augmented Renal Clearance.

Background And Objective: Patients with severe trauma exhibit augmented renal clearance, which can alter the dosing requirement of renally eliminated drugs. This study aimed to develop a population pharmacokinetic model for levetiracetam in patients with severe traumatic brain injury and aneurysmal subarachnoid hemorrhage, and use it to describe optimal dosing regimens.

Methods: This was a prospective open-label observational study.

Framework to Support the Process of Decision-Making on Life-Sustaining Treatments in the ICU: Results of a Delphi Study.

Objectives: To develop a consensus framework that can guide the process of decision-making on continuing or limiting life-sustaining treatments in ICU patients, using evidence-based items, supported by caregivers, patients, and surrogate decision makers from multiple countries.

Design: A three-round web-based international Delphi consensus study with a priori consensus definition was conducted with experts from 13 countries. Participants reviewed items of the decision-making process on a seven-point Likert scale or with open-ended questions.

Population pharmacokinetics of total and unbound concentrations of intravenous posaconazole in adult critically ill patients.

Background: The population pharmacokinetics of total and unbound posaconazole following intravenous administration has not yet been described for the critically ill patient population. The aim of this work was, therefore, to describe the total and unbound population pharmacokinetics of intravenous posaconazole in critically ill patients and identify optimal dosing regimens.

Methods: This was a prospective observational population pharmacokinetic study in critically ill adult patients with presumed/confirmed invasive fungal infection.

A pharmacokinetic case study of intravenous posaconazole in a critically ill patient with hypoalbuminaemia receiving continuous venovenous haemodiafiltration.

This article reports a pharmacokinetic case study of intravenous posaconazole in a 49-year-old male patient with intra-abdominal sepsis and hypoalbuminaemia receiving continuous venovenous haemodiafiltration. Concentration-time data following 300 mg intravenous posaconazole was analysed using a population pharmacokinetics approach. The 300-mg intravenous dose appears to be adequate for the treatment of yeast infections; however, for the treatment of invasive aspergillosis in isolated cases of critically ill patients with hypoalbuminaemia, the current dosing may not achieve desired exposure, although steady state exposure data are needed.

Pharmacokinetics of Intravenous Posaconazole in Critically Ill Patients.

To date, there is no information on the intravenous (i.v.) posaconazole pharmacokinetics for intensive care unit (ICU) patients.
