Steady-state trough serum and epithelial lining fluid concentrations of teicoplanin 12 mg/kg per day in patients with ventilator-associated pneumonia.
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.


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


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


METHODS
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.


RESULTS
The median total and free concentrations of teicoplanin in serum at trough were 15.9 microg/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.
