· This model is the most common compartment model used in pharmacokinetics. It consists of one or more peripheral compartments connected to the central compartment in a manner similar to connection of satellites to a planet.

A drug follows first order (i.e. linear) two compartment pharmacokinetics. After looking in the literature we find a number of parameter values for this drug. These numbers represent the micro constants for this drug. 2013-07-03 Pharmacokinetics.

Each compartment 2. One Compartment Open Model: When a drug is given as rapid i.v. bolus, the entire dose of the drug enters the body 3. Two Compartment Open Pharmacokinetics, sometimes abbreviated as PK, is a branch of pharmacology dedicated to determine the fate of substances administered to a living organism. The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc.

MabCampath pharmacokinetics followed a 2-compartment model and displayed non-linear elimination kinetics.

Although these com-partments have no physiological or anatomical meaning, it is assumed that the central compartment comprises tissues that are highly perfused such as heart, lungs, kidneys, liver and brain. 2-Compartment Model Drug enters the central compartment (or compartment 1) from somewhere outside of the body. Drug then leaves the central compartment by one of two paths: the peripheral compartment (also called compartment 2) the peripheral compartment (also called compartment 2) or drug leaves 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 dose/plasma concentration relationship.

Pharmacokinetics are classically represented by compartment models, such as the one-compartment model shown to the right. This model has a single volume and flow. The attraction of the one-compartment model is its simplicity. Pharmacokinetics to Compartmental Models Poggesi et al., Nerviano Medical Science . Gent, 24 August 2007/avpeer. 17.
