Figure 6From: Physiologically based pharmacokinetic modeling of arterial – antecubital vein concentration differenceComparison of ketamine PBPK model arterial (red) and antecubital vein (blue) concentrations with the experimental data (squares) of Persson et. al. [12] (top panel). The bottom panel compares the model antecubital vein/arterial concentration ratio (black line) versus the experimental values (squares).
