Models of Hepa
To the Editor:
A recent study by Jones and coworkers on the role of protein binding in hepatic drug elimination (1) warrants a second look. These authors found that increased extracellular binding due to addition of al-acid glycoprotein did not diminish the extraction of propranolol by the perfused rat liver. From this central finding, they reach a number of conclusions regarding the validity of various models of hepatic drug elimination. However, the authors do not address the possibility that their results may reflect Type I1 error: failure to confirm a valid hypothesis because of the insensitivity of the methods used.

The distributed-tubes model of hepatic elimination is extended to include intermixing between sinusoids, resulting in the formulation of a new, interconnected-tubes model. The new model is analysed for the simple case of two interconnected tubes, where an exact solution is obtained. For the case of
