Linezolid

 

Target Concentration

24 h area under the curve (unbound concentration) greater than 100 mg/L*h/MIC (Santimaleeworagun, Changpradub et al. 2021)

“the MIC median (MIC50), MIC for 90% growth (MIC90), and range for linezolid were 1.5 µg/mL, 2 µg/mL, and 0.72 - 2 µg/mL, respectively” (Santimaleeworagun, Changpradub et al. 2021)

The NextDose default MIC for linezolid is 2 mg/L. The MIC can be changed by adding MIC observations to patient data.

The occasion by occasion table of parameters and other variables shows the Bayesian estimate of clearance (CL L/h), the % difference of the Bayesian clearance from the group clearance value (fCL%), the Bayesian estimate of volume of distribution (V L), the % difference of the Bayesian volume from the group volume value (fV%), the Bayesian estimate of bioavailability (F), the % difference of the Bayesian bioavailability from the group bioavailability value (fF%), the predicted fat free mass (FFM kg), the predicted renal function (RF%), the minimum inhibitory concentration used for the target (MIC) and the Bayesian estimate of the baseline platelet count (PLT0).
