A general estimation of mean residence time (MRT) in an effect compartment E, associated with a linear mammillary n-compartment model is presented: elimination takes place from the central and the effect compartments. Even though no sample is available from E, the MRT of the drug in this compartment can be estimated after intravenous or oral administration. Furthermore, the effect of MRT is independent of the route of administration. Also, with no new calculation, the method provides the area under the amount-time curve in compartment E.

D014018	Tissue Distribution	Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.	Distribution, Tissue,Distributions, Tissue,Tissue Distributions
