The Sheiner and Beal method is crucial for evaluating predictive performance in pharmacokinetic studies. This work clarifies its practical application, addressing common confusions and detailing its use.

Area of Science:

  • Pharmacometrics
  • Pharmacokinetic modeling
  • Drug development

Background:

  • The Sheiner and Beal method is a foundational tool for assessing predictive performance in pharmacokinetic (PK) studies.
  • Its application in PK literature has become widespread but is often inconsistent, leading to confusion.
  • Original publications lack detailed guidance for practical implementation, making its use an art.

Purpose of the Study:

  • To clarify the practical application of the Sheiner and Beal method.
  • To address ambiguities and confusions identified in its recent use within pharmacokinetic studies.
  • To provide detailed guidance beyond the original publication for accurate implementation.

Main Methods:

  • Review and analysis of existing literature employing the Sheiner and Beal method.
