Brain microdialysis study of meropenem in two patients with acute brain injury.
Concentrations of unbound meropenem in the cerebral extracellular fluid (ECF) of two patients with acute brain injury were assessed by microdialysis. Brain ECF unbound-meropenem concentrations were lower than serum unbound-meropenem concentrations, with brain-to-serum area under the concentration-time curve ratios of 0.73 and 0.14. A pharmacokinetic model was developed to fit the experimental data adequately.
