The in silico prediction of pharmacokinetic behaviour in paediatric patients is not intended to replace clinical studies, however, it provides a valuable aid to decision-making with regard to first-time dosing in children and study design.
'In silico' simulations to assess the 'in vivo' consequences of 'in vitro' metabolic drug-drug interactions.

Predictions of the effects of liver cirrhosis on drug clearance are of potential value in the design of clinical studies during drug development and, clinically, in the assessment of likely dosage adjustment.

The collected data presented in this paper provide a potentially useful singular resource for key parameters needed for PBPK modelling in pregnancy, which facilitates the risk assessment of environmental chemicals and therapeutic drug dose adjustments in the pregnant population.

PBPK–IVIVE linked models have repeatedly shown their value in guiding decisions when predicting the effects of intrinsic and extrinsic factors on PK of drugs, and a review of the achievements and shortcomings of the models might suggest better strategies in extending the success of PBPK-IVIVE to pharmacodynamics (PD) and drug safety.

The PBPK model is a useful tool to evaluate different dosing regimens during T3 for drugs cleared primarily via CYP3A metabolism, and a sensitivity analysis suggested that CYP 3A induction in T3 is most likely hepatic and not intestinal.
A pregnancy physiologically based pharmacokinetic (p-PBPK) model for disposition of drugs metabolized by CYP1A2, CYP2D6 and CYP3A4.
