Pharmacokinetic two-compartment model Pharmacokinetics refers to the rate and extent of distribution of a drug to different tissues, and the rate of elimination of the drug. Pharmacokinetics can be reduced to mathematical equations, which describe the transit of the drug throughout the body, a net balance sheet from absorption and distribution to metabolism and excretion. Multicompartmental/Two Compartment Body Model 1 Two Compartment Body Model and Vd Terms by Jeff Stark In a one-compartment model, we make two important assumptions: (1) Linear pharmacokinetics - By this, we mean that elimination is first order and that pharmacokinetic parameters (ke, Vd, Cl) are not affected by the amount of the dose. Of course, a The data obtained were fitted with a two-compartment open model to obtain an effective permeability and an effective clearance. Both parameters decreased with increasing molecular radius for dextrans. Values for albumin were considerably less than expected on the basis of molecular radius, presumably due to the configuration, charge, and binding In the pharmacokinetic two-compartment model, the rate coefficients are determined by the physiology and the specific drug properties.

Benet, Sidney Riegelman, Department of Pharmacy, University of California, San Francisco Medical Center, San Francisco, CA 94122 Department of Pharmacy, University of California, San Francisco Medical Center San Francisco CA 94122 Abstract A Two compartment model Drugs which exhibit a slow equilibration with peripheral tissues, are best described with a two compartment model. Example Vancomycin is the classic example, it's distribution phase is 1 to 2 hours. Therefore, the serum level time curve of vancomycin may be more accurately represented by a 2-compartment model.

The two compartment model has a central compartment, C, consisting of blood and highly perfused organs such as the liver, kidney, lungs, etc., and also a 

Drug then leaves the central compartment by one of two paths: the peripheral compartment (also called compartment 2) or; drug Seminar on pharmacokinetic parameters of two compartment open model 1. PHARMACOKINETIC PARAMETERS OF TWO COMPARTMENT OPEN MODELSeminar ByAjmeera DivyaM.
