That PK/PD relationship, along with the population variability in drug exposure, is used to determine the probability of target attainment (PTA) of the PK/PD index at a specified minimum inhibitory concentration (MIC) for a selected target value. The PTA is used to identify the pharmacodynamic cutoff value (CO<sub>PD</sub>), which is one of the three components used to establish the clinical breakpoint. A challenge encountered when defining the CO<sub>PD</sub> is that the available PK information typically reflects total (free plus protein-bound) plasma concentrations. However, it is the unbound drug concentrations that exert the therapeutic effects and how the population fraction unbound (<i>fu</i>) incorporated into the CO<sub>PD</sub> assessments can markedly influence the CO<sub>PD</sub>.
