Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glutathione treatments are limited by its unstable nature, leading to oxidation and poor absorption, which hinders its therapeutic effectiveness in various disease conditions.
Innovation Solution
A topical composition comprising reduced, nanonized L-glutathione stabilized with gamma cyclodextrin, ascorbic acid, and optional additives like dexpanthenol and sodium hyaluronate, facilitating transdermal delivery and protection against oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glutathione is administered orally, then it can be delivered to the body, but it undergoes oxidation and poor absorption in the digestive tract
Solution Approach 1:
The patent uses cyclodextrin as an intermediary carrier to encapsulate glutathione, protecting it from oxidation in the digestive tract and facilitating its transport through the gastrointestinal system. The cyclodextrin forms an inclusion complex with glutathione, shielding the thiol group from oxidative damage while enabling oral delivery.
Solution Approach 2:
The patent employs nanonization to reduce glutathione particle size to the nanoscale range, which fundamentally changes its physical properties. This size reduction dramatically improves absorption efficiency by increasing surface area and enabling penetration through biological membranes, while the nanoscale form also enhances stability against oxidation.
2Stability of the object's composition
If glutathione is stabilized against oxidation, then its therapeutic effectiveness is improved, but its absorption and delivery to target tissues remains limited
Solution Approach 1:
The patent creates a nested structure where glutathione is encapsulated within cyclodextrin molecules, forming an inclusion complex. This nested arrangement protects the inner glutathione molecule from external oxidative environments while the outer cyclodextrin layer facilitates transport through biological barriers, simultaneously achieving both stability and absorption.
3Reliability
If glutathione is delivered transdermally, then digestive tract absorption issues are bypassed, but the stability during transdermal delivery must be maintained
Solution Approach 1:
The patent uses cyclodextrin as an intermediary carrier for transdermal delivery, where it encapsulates glutathione and facilitates its penetration through the skin barrier. The cyclodextrin protection mechanism remains active during transdermal transport, preventing oxidation while enabling efficient delivery to target tissues beneath the skin.
