Abstract

In order to respond to the flood of new active ingredients currently being generated by combinatorial chemistry or molecular biological synthesis, selection procedures able to filter out rapidly and economically those drug candidates with the highest development potential are required.
This necessitates the measurement of fundamental biopharmaceutical parameters very early in the drug development process. Any pharmaceutically active agent must be able to overcome the body's natural protective mechanisms. A broad variety of biological barriers can be simulated in the laboratory by cell monolayer models. Apart from ethical aspects, the advantage of these in vitro test systems is that permeability studies can be performed at high throughput rates under controlled and reproducible conditions. The validity of such a model is ultimately reflected in its ability to accurately predict the behaviour of an active ingredient at the corresponding in vivo barrier.
