Hyaluronidase-Enhanced Botulinum Toxin Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating cholinergically-influenced disorders, such as overactive bladder and hyperhidrosis, require multiple injections of botulinum toxin, which can be painful and inefficient due to the large size of the toxin molecule limiting its diffusion.
Innovation Solution
The use of extracellular matrix digesting enzymes, like hyaluronidase, to enhance the diffusion of botulinum toxin by breaking down the extracellular matrix, allowing for reduced or eliminated injections by administering the enzyme followed by the toxin, either through instillation or topical application, to achieve therapeutic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple injections of botulinum toxin are administered to treat cholinergically-influenced disorders, then therapeutic effectiveness is achieved, but patient comfort deteriorates due to pain and inconvenience from multiple needle penetrations
Solution Approach 1:
The patent introduces an extracellular matrix digesting enzyme as an intermediary substance that facilitates the diffusion and distribution of botulinum toxin throughout the target tissue. This enzyme acts as a mediator between the toxin and the extracellular matrix, breaking down the matrix structure to enable more effective and uniform toxin penetration, thereby reducing the number of injections needed while maintaining therapeutic effectiveness and improving patient comfort
2Reliability
If multiple injections of botulinum toxin are administered to ensure adequate diffusion and coverage, then treatment efficacy is improved, but the complexity and time required for treatment increases
Solution Approach 1:
The patent applies preliminary action by administering the extracellular matrix digesting enzyme before the botulinum toxin to prepare the tissue structure. This preliminary enzymatic breakdown of the extracellular matrix creates favorable conditions for subsequent toxin diffusion, ensuring adequate coverage and efficacy with fewer injections and reduced treatment complexity
Solution Approach 2:
The extracellular matrix digesting enzyme serves as a facilitator that enhances toxin distribution throughout the target area. By degrading the extracellular matrix structure, the enzyme creates pathways that allow the botulinum toxin to diffuse more effectively, thereby achieving treatment efficacy with reduced injection numbers and simplified treatment protocols
