Solution Overview

Problem

Current treatments for drug overdose and intoxication, particularly from substances like opioids and stimulants, are inadequate in effectively reversing the effects and often lead to secondary complications such as renarcotization or precipitated opioid withdrawal.

Innovation Solution

A pharmaceutical combination of a sequestration agent, such as cucurbituril, pillararene, cyclodextrin, or calixarene, and a central nervous system (CNS) active agent, like naloxone, is administered simultaneously or sequentially to sequester and displace toxic agents from receptors, preventing renarcotization and facilitating rapid clearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CNS active agents are administered to treat drug overdose, then the toxic effects are reversed, but repeated high doses are required leading to secondary complications such as renarcotization or precipitated opioid withdrawal

Engineering Contradiction:
Improveeffectiveness of overdose treatmentVSAvoidsecondary complications
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

A sequestration agent acts as an intermediary substance that binds to and sequesters the toxic agent (opioid or stimulant) in the bloodstream, preventing it from binding to CNS receptors. This mediator approach allows the toxic agent to be removed from its harmful role without directly stimulating or blocking CNS receptors, thereby reversing toxic effects while avoiding secondary complications like renarcotization or precipitated withdrawal

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sequestration agent extracts the toxic agent from the biological system by forming a complex that can be eliminated. The patent describes how the sequestration agent binds to the toxic agent with high affinity, effectively pulling it out of circulation and preventing re-binding to receptors, thus eliminating the need for repeated high doses of CNS active agents

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If high doses of CNS active agents are administered to ensure effective treatment, then overdose symptoms are reversed, but the risk of secondary complications increases

Engineering Contradiction:
Improvespeed of overdose reversalVSAvoidsecondary complications
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The sequestration agent serves as a mediator that achieves rapid overdose reversal through direct binding to the toxic agent in the bloodstream, eliminating the need for high doses of CNS active agents. This intermediary mechanism provides fast action by directly removing the toxic agent from circulation rather than relying on receptor competition

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful presence of the toxic agent in the bloodstream into a beneficial binding opportunity for the sequestration agent. By designing the sequestration agent to have high affinity for the toxic agent, the harmful substance becomes the very target that enables rapid clearance and effective treatment without secondary complications

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
