Solution Overview

Problem

Existing treatments for conditions associated with glutathione depletion, such as neurological and lung diseases, alcohol and drug poisoning, and chemotherapy toxicity, are limited by glutathione's instability and poor absorption, leading to ineffective therapeutic outcomes.

Innovation Solution

A topical composition comprising reduced, nanonized L-glutathione stabilized with gamma cyclodextrin, ascorbic acid, and optional additives like dexpanthenol and sodium hyaluronate, which facilitates transdermal delivery and protects glutathione from oxidation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If glutathione is administered in conventional forms, then it can provide therapeutic effects for glutathione depletion conditions, but it suffers from instability and poor absorption leading to ineffective therapeutic outcomes

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidglutathione stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by nanonizing glutathione particles to reduce their size to the nanoscale range, which fundamentally alters the physical properties of glutathione. This size reduction increases surface area to volume ratio, enhances solubility, and improves penetration through biological barriers such as the skin, thereby resolving the contradiction between stability and therapeutic effectiveness

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses penetration enhancers as intermediary substances that facilitate the delivery of nanonized glutathione through the skin. These enhancers temporarily modify the skin barrier properties, allowing glutathione to penetrate effectively while maintaining its stability, thus enabling therapeutic effectiveness without compromising stability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If glutathione is administered in conventional forms, then it can address glutathione depletion conditions, but it exhibits poor absorption preventing effective delivery to target tissues

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidabsorption efficiency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By changing the physical parameter of particle size to the nanoscale, the patent dramatically improves absorption efficiency. The nanonized form of glutathione can penetrate through the stratum corneum and reach deeper skin layers and systemic circulation, enabling effective delivery to target tissues for treating various conditions

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Penetration enhancers serve as mediators that facilitate the absorption of nanonized glutathione. These substances temporarily alter the skin barrier function, creating pathways for glutathione to penetrate efficiently, thereby achieving reliable therapeutic effectiveness

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If glutathione is stabilized using conventional methods, then it may improve shelf life, but it reduces bioavailability and transdermal absorption

Engineering Contradiction:
Improveglutathione stabilityVSAvoidbioavailability
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent resolves this contradiction by nanonizing glutathione, which changes its physical state and surface properties. The nanoscale particles maintain stability during storage while simultaneously exhibiting enhanced bioavailability and transdermal absorption capabilities, allowing both stability and quantity of substance to be optimized

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

By segmenting glutathione into nanoscale particles, the patent increases the total surface area while maintaining the chemical integrity of each particle. This segmentation allows the substance to remain stable as individual particles while collectively providing high bioavailability and absorption efficiency

Inventive Principle:
Principle #1Segmentation
