Topical Wound Healing Composition for Refractory Diabetic Ulcers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wound healing therapies often fail to effectively treat hard-to-heal wounds, particularly those of diabetic origin, leading to potential amputation and significant morbidity, as they do not adequately address the complex healing process disrupted by conditions like diabetes, peripheral vascular disease, and lymphedema.
Innovation Solution
A method involving the topical application of a wound healing composition comprising calcium channel blockers, alpha-adrenergic antagonists, direct vasodilators, phosphodiesterase type five inhibitors, hemorrheologic agents, dermal penetrating agents, and topical stimulating agents, which are administered to the outer periphery of the wound to enhance healing by improving blood flow and tissue oxygenation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wound healing therapies are used, then treatment simplicity is maintained, but healing effectiveness deteriorates for hard-to-heal wounds
Solution Approach 1:
The patent combines multiple pharmacologically active compounds with different mechanisms of action into a single topical formulation. This includes compounds that target inflammation, angiogenesis, and tissue regeneration simultaneously, allowing the treatment to address multiple aspects of wound healing failure in one application rather than requiring separate treatments for each mechanism.
Solution Approach 2:
The invention uses a composite formulation containing multiple active ingredients with complementary therapeutic effects. This composite approach allows the treatment to overcome the limitations of single-agent therapies by integrating the benefits of different compound classes that work synergistically to promote wound healing in refractory cases.
2Reliability
If advanced topical formulations with multiple compounds are used, then healing effectiveness improves, but formulation complexity increases
Solution Approach 1:
The topical formulation is designed to perform multiple therapeutic functions simultaneously within a single product. The formulation includes compounds that address inflammation, promote blood vessel formation, stimulate tissue growth, and prevent infection, making it a universal treatment that handles various aspects of wound healing failure without requiring multiple separate products.
Solution Approach 2:
Multiple pharmacologically active compounds with different mechanisms of action are merged into one topical formulation. This integration allows the treatment to address multiple pathological processes underlying hard-to-heal wounds simultaneously, improving efficacy while consolidating what would otherwise require multiple separate applications.
3Object-affected harmful factors
If topical application to the outer periphery is used, then systemic side effects are reduced, but local healing effectiveness must be maintained
Solution Approach 1:
The treatment is applied locally to the outer periphery of the wound rather than systemically, creating a concentrated therapeutic effect at the target site. This localized application ensures that the high concentrations of active compounds act directly on the wound margins where healing is needed, while minimizing exposure to the rest of the body and reducing potential systemic side effects.
Solution Approach 2:
The topical formulation acts as an intermediary that delivers therapeutic compounds directly to the wound site through local application. By applying to the outer periphery, the formulation creates a gradient of drug concentration that penetrates inward to the wound bed, ensuring effective local treatment while avoiding the need for systemic administration and its associated risks.
