“…They make use of mathematical models to assess drug absorption, distribution, metabolism and excretion (Pieper & Bertau, 2010). The most commonly used models are the physiologically-based pharmacokinetics (Leahy, 2003), the systems biology-based drug metabolism simulation (Bugrim et al, 2004), the quantitative structure-activity relationship modelling (Chang & Swaan, 2006), and the computational oral absorption simulation (Sugano, 2009). More specific information on the topic has been recently reviewed by Bertau et al (2008) and Pieper & Bertau (2010).…”
