Drug Accumulation During Multiple Dosing: Repetitive IV Injections

Drug Accumulation During Multiple Dosing: Repetitive IV Injections

Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...

Multicompartment Models: Overview

Multicompartment Models: Overview

Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Drug Dosing: Geriatric Patients

Drug Dosing: Geriatric Patients

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Model Approaches for Pharmacokinetic Data: Compartment Models

Model Approaches for Pharmacokinetic Data: Compartment Models

Compartmental analysis is a widely adopted approach to characterizing drug pharmacokinetics. It uses compartment models that conceptualize the body as a collection of reversibly communicating compartments, each representing a group of tissues exhibiting similar drug distribution characteristics. The movement rate of the drug between these compartments is typically described by first-order kinetics.
Two primary types of compartment models are recognized: mammillary and catenary. The more...

Three-Compartment Open Model

Three-Compartment Open Model

The three-compartment open model is a pharmacokinetic model used to describe the distribution and elimination of drugs following extravascular administration. It comprises a central compartment representing the plasma and two peripheral compartments. The highly perfused peripheral compartment represents organs and tissues with a rich blood supply, such as the liver, kidneys, and lungs. The scarcely perfused peripheral compartment represents tissues with lower blood supply, such as adipose...

Background:

Human selection errors in automated dispensing cabinets (ADCs) pose a significant patient safety risk.
Optimizing medication layout within ADCs is crucial for minimizing these errors and improving efficiency.
Current ADC design may not fully leverage data-driven approaches for layout optimization.

Purpose of the Study:

To formulate the multiple-drawer medication layout problem for ADCs.
To develop a heuristic approach for solving large-scale medication layout problems.
To evaluate the impact of an analytical approach on ADC design and medication selection accuracy.

Main Methods:

Formulation of the medication layout problem as a quadratic assignment problem.
Development of a medication pair similarity rating for layout evaluation.
Implementation and testing of a heuristic algorithm using hospital ADC transaction data.

Main Results:

The heuristic approach effectively addresses industry-sized problem instances.
The developed method demonstrates potential for significant improvements in medication selection accuracy.
Computational experiments validate the approach's utility in ADC design trade-offs.

Conclusions:

An analytical approach to the multiple-drawer medication layout problem can enhance ADC performance.
The developed heuristic offers a practical solution for optimizing medication placement.
Future research should explore further refinements and broader applications of this methodology.
