Drug efficacy depends on the amount of a preparation reaching the target tissue (grade of tissue transfer). In this experiment, we established the normal albumin concentration of a healthy adult (600 μ M) or a low-albumin state indicating marked liver hypofunction (100 μ M) on a cell membrane plate, and evaluated the cell membrane permeability of the probe agents. The cell membrane permeability of phenytoin or valproate depended on the concentration of albumin. Probe agent site-I and -II inhibitors, bucolome and oleic acid, respectively, increased the cell membrane permeability. In the future, the cell membrane permeability of probe agents should be further investigated to estimate the tissue transfer of agents based on various laboratory data (albumin, free fatty acids, uremic toxins, and bilirubin).
