WebThe ratio of the concentration in tissue at steady state to that in plasma at steady state is the tissue to plasma partition coefficient denoted by Kp. The assumption in the derivation of eqn [18] is that at steady state the free concentration between tissue and plasma are equal. WebThe goal of blood plasma partitioning (BPP) is to measure compound concentration ratio between blood and plasma. It is measured by blood concentration ratio/plasma concentration ratio (C b /C p) and is an important parameter for predicting whole body pharmacokinetics. Some compounds may have high degree of affinity for the red blood …
