Background:
Pharmacokinetic (PK) models are essential for understanding drug behavior in the body.
Accurate parameter estimation and simulation are crucial for effective drug dosing and clinical decision-making.
Existing computational tools may be limited in accessibility or scope for certain applications.
Purpose of the Study:
To develop and present a versatile calculator program package for pharmacokinetic analysis.
To enable the computation of parameters for both one and two compartment open models.
To facilitate the simulation of drug dosing regimens and the evaluation of drug clearance.
Main Methods:
Implementation of the peeling method for parameter estimation in pharmacokinetic models.
Development of algorithms for the 'one compartment open model' with first-order absorption.
Development of algorithms for the 'two compartment open model' with rapid intravenous injection.
Inclusion of an Area Under Curve (AUC) calculation program for clearance evaluation.
Adaptation of algorithms for TI 58, 59 and HP 97 calculators.
Main Results:
The calculator package successfully computes parameters for the specified pharmacokinetic models.
The program allows for accurate simulation of drug concentrations for single and repetitive doses.
The Area Under Curve (AUC) program effectively evaluates drug clearance.
The developed algorithms are functional on widely available programmable calculators.
Conclusions:
The calculator program package provides a practical tool for pharmacokinetic parameter computation and simulation.
This tool can be readily applied in clinical settings to support drug therapy management.
The accessibility of the program on standard calculators enhances its utility in diverse clinical environments.
