Computational models play an increasing role in pharmaceutical research and development, since they offer an efficient way for storing,
representing and analyzing experimental data at each stage of (pre-)clinical development. Physiologically-based pharmacokinetic (PBPK)
models are a special form of pharmacokinetic models which represent the processes underlying the distribution of a substance within the
human body mechanistically at a high level of detail. Based on generic drug distribution models and extensive collections of physiological parameters
they thus enable a comprehensive simulation of drug pharmacokinetics at the whole-body scale. Moreover, structural refinements such as metabolization processes
or active transport can easily be introduced into the basic PBPK models such that structural hypotheses can be evaluated.
Using different exemplary case studies we show here how computational models allow the investigation of mechanisms governing a specific pharmacokinetic behavior.
Simultaneous consideration of a drug's modes of action at the cellular level enables construction of integrated multi-scale models based on which dose-effect relationships
can be investigated from a systems perspective. Such multi-scale models have amongst others been used for the correlation of genetic predisposition in a patient subgroup
with clinical endpoints. Computational models thereby significantly support assessment of crucial points in drug R&D such as (1) a rigorous evaluation of drug efficacy at an
early phase of clinical development, (2) avoidance of adverse effects and (3) development of individualized therapeutic designs.
