The following figure compares a model as typically represented in pharmacokinetics with the same model shown in the SimBiology model diagram. For this comparison, assume that you are modeling administration of a drug using a two-compartment model with any dosing input and linear elimination kinetics.

Pharmacokinetic two-compartment model divided the body into central and peripheral compartment. The central compartment (compartment 1) consists of the plasma and tissues where the distribution of the drug is practically instantaneous. The peripheral compartment (compartment 2) consists of tissues where the distribution of the drug is slower. Multicompartmental/Two Compartment Body Model 2 THE TWO COMPARTMENT MODEL i.v.

1-compartment pharmacokinetics is exhibited by a radiopharmaceutical which demonstrates a single disposition phase (i.e. a straight line) when the blood or plasma concentrations are plotted vs. time post-injection on a semi-logarithmic scale (Figure 2).

In order to establish a desired drug level in compartment 2 (blue line) the size and the frequency of the dosage are the available variables.

In practice it has been found that the pharmacokinetics of almost all drugs can be described adequately using no more than three compartments; many can be described using two compartments; and when pharmacokinetics are applied to specific clinical situations (e.g., to individualize a dose for a patient), the one-compartment model can usually provide a sufficient degree of accuracy to predict the …
