It is concluded that phenytoin absorbed from the intestine is recirculated via the bile, so that blood levels do not accurately reflect absorption. Phenytoin is loosely bound to serum proteins and is found in red cells in concentrations similar to those in plasma. It is rapidly lost from the blood stream after intravenous administration, which is an important factor to be considered in the treatment of status epilepticus.
