title: Consistency of the novel equations for determination of hepatic clearance and drug time course in liver that account for the difference in drug ionization in extracellular and intracellular tissue water.
abstract: Intrinsic clearances of seven diverse compounds in rat liver microsomes were measured at intracellular pH 7.0 and extracellular pH 7.4. The obtained values were quite close for each compound. These results confirm the validity of the recently published novel equations for calculation of hepatic clearance and drug time course in liver that account for pH differences in extracellular water and hepatocytes.
