This article describes the experimental set-up and pharmacokinetic modeling of of [(11)C]verapamil was well described by a two-compartment model.

Note that kp = k12, kd = k21. (D) Two compartment model defined in terms of the drug amount, where Nbl is the amount of drug in blood (mg), and Np is the amount in peripheral tissue (mg). (E) Three compartment model with the addition of a tumor “compartment” where Nt is the amount of drug in the tumor.

A two-compartment model assumes that, following drug adminis-tration into the central compartment, the drug distributes between that compartment and the peripheral compartment. However, the drug does not achieve instantaneous distribution, i.e. equilibration, between the two compartments. The 2-compartment model considers the entire body, and all of the organs and tissues to be two buckets, but all drug must leave the body through a single bucket. In many ways the compartmental models are very similar to the heart chamber model.

Use of a two-compartment model to assess the pharmacokinetics of human ethanol metabolism. The relationship between blood ethanol concentration and hepatic ethanol metabolism commonly is calculated using the Michaelis-Menten equation and a one-compartment model that assumes equality of blood and hepatic ethanol concentrations. Pharmacokinetics to Compartmental Models Poggesi et al., Nerviano Medical Science . Gent, 24 August 2007/avpeer. 17.

If drug is administered in animals body through i.v. injection, it is first distributed into the highly perfused tissues (central compartment) and thereafter to less perfused tissues (peripheral compartment).
