Differentiating Itraconazole Formulations Based on the Flux through Artificial Lipophilic Membrane

It was demonstrated that flux measurements provide more in-depth understanding of supersaturated systems than solute concentration measurements alone. This study used miniaturized dissolution – permeation apparatus (μFLUX) to compare flux of itraconazole (Figure 1) from several formulations for which in-vivo rat PK data were available. The goal of the study was to evaluate the formulation benchmarking ability of the instrumental setup.
