In principle, in vitro solubility/permeability/dissolution experiments are useful to determine those properties of drugs and/or dosage forms that can help understand their behavior in vivo. However, generally, these measurements are conducted independently, with little concern for the physiological situation, and the resulting data have little relevance to in vivo performance. Since intestinal permeability is a key factor determining drug absorption, an in vitro system that permits to evaluate not only dissolution but also permeation would be very valuable in establishing a link between in vitro measurements and in vivo performance.
