| Measure | Time frame |
|---|---|
| Primary end point(s): The time versus unbound linezolid concentration profiles in the ISF of inflamed tissue and non-inflamed subcutaneous adipose tissue and in plasma of diabetes patients after multiple doses will be determined. The following PK parameters will be determined for all compartments. Main outcome variables: Area under the concentration time curve (AUC), maximum concentration (Cmax), half-life (t1/2), time of maximum concentration (tmax). Secondary outcome variables: ratios of AUC and Cmax of different compartments (inflamed vs. non-inflamed, plasma vs. tissue), time above minimum inhibitory concentrations of linezolid for susceptible bacteria (T>MIC), ratio of Area under the concentration vs. time curve form 0 to 24 hours (AUC0-24)/MIC. ;Main Objective: 1) Determination of concentrations of linezolid in plasma and the ISF of inflamed tissue and non-inflamed s.c. tissue of diabetes patients after a single dose. Tissue concentrations will be related to corresponding unbound plasma concentrations. 2) Determination of concentrations of linezolid in plasma and the ISF of inflamed tissue and non-inflamed s.c. tissue of diabetes patients after multiple doses. Tissue concentrations will be related to corresponding unbound plasma concentrations. 3) To explore, if there is an influence of inflammation on tissue pharmacokinetics of linezolid. 4) Calculation of pharmacokinetic/pharmacodynamic indices to estimate target site efficacy of linezolid. ;Secondary Objective: | — |
