Noncompartmental vs. Compartmental Approaches to.
Noncompartmental Analysis. Noncompartmental analysis (NCA) lets you compute pharmacokinetic (PK) parameters of a drug from the time course of measured drug concentrations. This approach does not require the assumption of a specific compartmental model. NCA is often used to determine the degree of exposure following administration of a drug.
This chapter discusses noncompartmental versus compartmental approaches to pharmacokinetic (PK) analysis. The evaluation of PK parameters is an essential part of understanding the way drugs function in the body. PK parameters fall basically into two categories. One category is qualitative or descriptive, where the parameters are observational.

A CRITIQUE OF COMPARTMENTAL ANALYSIS Kenneth Zierler .9176 Department of Physiology, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21205 INTRODUCTION TO THE GENERAL EQUATIONS Purpose of This Review In 10 years, fro.m 1969 thro.ugh 1978, 341 articles were indexed under compartmental analysis.
Example 11.3: Compartmental Analysis. Numerical Considerations An important class of nonlinear models involves a dynamic description of the response rather than an explicit description. These models arise often in chemical kinetics, pharmacokinetics, and ecological compartmental modeling. Two examples are presented in this section. Refer to.
Non Compartmental Analysis Table XIX-2 Typical Cp versus Time Data after IV Bolus Administration. Non compartmental methods can be used to determine certain pharmacokinetic parameters without deciding on a particular compartmental model.
When performing non-compartmental analysis, the area under the concentration-time curve (AUC) is calculated to determine the total drug exposure over a period of time. Together with Cmax, these two parameters are often used to define the systemic exposure of a drug for comparison purposes. For example, in bioequivalence trials, the entire.
These curves are analyzed in multiple ways to investigate the drug properties. The major classification is between compartmental analysis and noncompartmental analysis (Gabrielsson and Weiner, 2000; Sheiner, 1984). Noncompartmental analysis is based on the graphical techniques performed on the experimental data of the measured blood concentrations.
THE FUNDAMENTAL PRINCIPLES OF COMPARTMENTAL PHARMACOKINETICS ILLUSTRATED BY RADIOPHARMACEUTICALS COMMONLY USED IN NUCLEAR MEDICINE STATEMENT OF LEARNING OBJECTIVES: The primary goal of this continuing education lesson is to demonstrate the application of commonly used pharmacokinetic methods of analysis to radiopharmaceuticals. A review of.
Compartmental analysis. Compartmental PK analysis uses kinetic models to describe and predict the concentration-time curve. PK compartmental models are often similar to kinetic models used in other scientific disciplines such as chemical kinetics and thermodynamics. The advantage of compartmental over some noncompartmental analyses is the.
Recently, Zhang et al (21) have presented compartmental models for the analysis of SARS transmission patterns and outbreak control measures in China. And Ruan et al (28) have proposed a.
Applications of Differential Equations Compartmental Analysis More Examples in Mathematica (continued from last page.) Your results should have been very similar to the following: The graph very clearly illustrates the fact that regardless of the initial condition, the amount of salt in the tank will always approach 800 pounds.
Compartmental modeling This is a very short summary of the notes from my two-hour lecture. These notes were not originally meant to be distributed, and so they are far from being complete. A comprehensive introduction to compartmental modeling can be found for example in the book Compartmental Analysis in Biology and Medicine by J. A.
