Abstract

Objective:

To determine the steady-state trough serum and epithelial lining fluid (ELF) concentrations of teicoplanin 12 mg/kg per day in critically ill patients with ventilator associated pneumonia.

Design and setting:

Prospective, pharmacokinetic study in the surgical intensive care unit in a university hospital.

Patients:

Thirteen adult patients with nosocomial bacterial pneumonia on mechanical ventilation were enrolled.

Interventions:

All subjects received a 30-min intravenous infusion of 12 mg/kg teicoplanin every 12 h for 2 consecutive days followed by 12 mg/kg once daily. Teicoplanin concentrations in serum and ELF were determined simultaneously 4–6 days after antibiotic administration started.

Measurements and results:

The median total and free concentrations of teicoplanin in serum at trough were 15.9 μg/ml (range 8.8–29.9) and 3.7 (2.0–5.4), respectively. The concentration in ELF was 4.9 (2.0–11.8).

Conclusions:

In critically ill patients with ventilator-associated pneumonia the administration of high teicoplanin doses is required to reach sufficient trough antibiotic concentrations in lung tissues at steady state. At that time trough-free concentrations of teicoplanin in serum and ELF are comparable.
