Solution Overview
Problem
Current transdermal patches for anti-inflammatory formulations have limitations such as low skin permeability and low loading capacity, resulting in reduced efficacy and increased side effects, necessitating the development of enhanced patches with higher anti-inflammatory activity and lower risk profiles.
Innovation Solution
Transdermal patches coated with a blend of Cymbopogon citratus oil, Zanthoxylum armatum oil, and Hedychium spicatum oil in specific weight proportions, combined with menthol, to provide a synergistic anti-inflammatory and analgesic effect with reduced toxicity and side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional transdermal patches are used for anti-inflammatory formulations, then the patch structure is simple and easy to manufacture, but the skin permeability is low and loading capacity is limited
Solution Approach 1:
The transdermal patch incorporates a multi-layer composite structure including a permeable membrane layer, adhesive layer, and protective layers. The permeable membrane is specifically designed to enhance drug permeability while the layered composite structure increases loading capacity without compromising manufacturability
Solution Approach 2:
The patch utilizes a porous permeable membrane as a key component that significantly enhances skin permeability. The porous structure allows for improved drug delivery through the skin while maintaining structural integrity and ease of manufacturing through standard lamination processes
2Reliability
If higher doses of anti-inflammatory medication are administered to achieve pain relief, then the therapeutic effect is improved, but side effects increase
Solution Approach 1:
The patch delivers anti-inflammatory medication locally to the affected joint area through controlled transdermal penetration. This localized delivery ensures therapeutic concentrations are achieved at the target site while minimizing systemic absorption and associated side effects
Solution Approach 2:
The permeable membrane acts as an intermediary that facilitates controlled drug release and penetration through the skin. This mediator enables sustained local delivery of anti-inflammatory agents, maintaining therapeutic efficacy while reducing the need for high systemic doses that cause side effects
