Drug Interaction Modeling System for Anesthesia Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for evaluating the combined effects of multiple anesthetic agents on a subject are inadequate, as they do not account for drug-drug interactions or individual subject characteristics, leading to suboptimal anesthesia administration and potential adverse effects.
Innovation Solution
A system and method for evaluating the synergism or antagonism of multiple drugs, including processing elements that model and display their interactions, allowing for tailored drug administration based on subject-specific characteristics, optimizing dosages for desired clinical outcomes while minimizing side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional single-drug modeling apparatus are used, then pharmacokinetic and pharmacodynamic parameters can be modeled, but drug-drug interactions and combined effects of multiple drugs are not accounted for
Solution Approach 1:
The patent combines multiple single-drug pharmacokinetic and pharmacodynamic models into a unified multi-drug modeling system. The system integrates individual drug models (e.g., propofol, remifentanil) with interaction models that calculate combined effects, allowing simultaneous evaluation of multiple drugs and their interactions on a single graphical display.
2Measurement precision
If complex mathematical manipulations are used for pharmacokinetic and pharmacodynamic modeling, then accurate drug behavior prediction is achieved, but clinical practicality is reduced
Solution Approach 1:
The patent introduces a computer system with graphical user interface as an intermediary between complex pharmacokinetic-pharmacodynamic calculations and the clinician. The system performs all mathematical manipulations automatically and presents results through intuitive graphical displays showing drug concentrations, effects, and interactions, eliminating the need for clinicians to manually perform complex calculations.
Solution Approach 2:
The patent creates visual copies of pharmacokinetic and pharmacodynamic data through graphical displays. Instead of requiring clinicians to interpret complex numerical tables and equations, the system generates visual representations including concentration-time curves, effect-site concentration graphs, and interaction surfaces that are easily interpretable at a glance.
3Reliability
If multiple drugs are administered to achieve desired clinical effects, then adequate anesthesia and analgesia are provided, but excessive dosages may prolong emergence and cause adverse effects
Solution Approach 1:
The patent implements feedback mechanisms where the modeling system continuously calculates predicted drug concentrations and effects based on administered doses, then uses this information to guide subsequent dosing decisions. The system provides real-time feedback on cumulative drug effects and interactions, allowing clinicians to adjust dosing to maintain therapeutic effects while avoiding excessive accumulation that would prolong emergence.

AI summary
Drug delivery models, displays, and systems may be configured to provide a clinician with readily intuitive information about the effects of one or more drugs on a subject. Interactive features may be included to provide a subject-specific model of the expected or predicted effects of one or more drugs on the subject. Additionally, interactive features that effect drug delivery to the subject may also be included. Drug delivery models, displays, and systems may be used in teaching, in advance of treatment, during treatment, or following treatment.
