Abstract Background There are various methods for predicting human pharmacokinetics. Among these a whole body physiologically-based pharmacokinetic WBPBPK model is useful because it gives a mechanistic description. However WBPBPK models cannot predict human pharmacokinetics with enough precision. This study was conducted to elucidate the primary reason for poor predictions by WBPBPK models and to enable better predictions to be made without reliance on complex concepts. Methods The primary reasons for poor predictions of human pharmacokinetics were investigated using a generic WBPBPK model that incorporated a single adjusting compartment SAC a virtual organ compartment with physiological parameters that can be adjusted arbitrarily. The blood flow rate organ volume and the steady state tissue-plasma
