Abstract
The average amount of drug in the body at steady state bar Xupon repetitive dosing in a twocompartment open system is related to the average steadystate plasma level bar Cby the apparent volume of distribution at steady state Vssrather than by Vβthe apparent volume of distribution at pseudodistribution equilibrium despite the fact thatbar Cis directly proportional to 1/VβMultiplication ofbar C by ddot V beta results in an overestimate ofbar Xthe magnitude of which depends on the distribution and elimination parameters of the drug The significance and utility of the volume parameters Vβand Vssemployed in multicompartment systems are considered
