Substance P Polymeric Carrier Wound Healing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for wound healing, particularly in denervated regions and sensitive areas like the cornea, are inefficient due to the need for frequent administrations of Substance P, leading to prolonged healing times.
Innovation Solution
The use of neuropeptides such as Substance P, combined with polymeric delivery carriers like hyaluronic acid, to enhance cellular proliferation and promote wound healing by increasing the dwell time of the neuropeptide, thereby reducing the number of administrations required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Substance P is administered frequently to promote wound healing, then wound healing is enhanced, but the treatment complexity and patient burden increase
Solution Approach 1:
The patent uses polymeric carriers as intermediary substances to deliver Substance P to the wound site. These carriers bind to Substance P and control its release, allowing less frequent administration while maintaining therapeutic effectiveness. The polymeric carrier acts as a mediator between the drug and the wound, enabling sustained delivery without requiring frequent injections.
Solution Approach 2:
The patent employs pre-formed polymeric conjugates of Substance P that are designed to release the neuropeptide over an extended period. By preparing these conjugates in advance with controlled release properties, the system eliminates the need for frequent re-administration, as each injection provides sustained therapeutic levels of Substance P throughout the wound healing process.
2Duration of action of moving object
If polymeric delivery carriers are used to increase Substance P dwell time, then administration frequency is reduced, but the composition complexity increases
Solution Approach 1:
The patent creates composite molecular structures by chemically conjugating Substance P with polymeric carriers. This composite material combines the therapeutic properties of Substance P with the sustained-release capabilities of the polymer, achieving extended dwell time while maintaining a relatively simple overall composition that consists of the conjugate molecule and physiological buffer.
3Ease of manufacture
If Substance P is used alone for wound treatment, then the treatment is simple, but the healing time is prolonged
Solution Approach 1:
The patent changes the temporal parameter of Substance P delivery by incorporating it into polymeric carriers with controlled degradation rates. This parameter change transforms the delivery profile from rapid clearance to sustained release, extending the effective dwell time of Substance P at the wound site and accelerating healing without complicating the fundamental treatment approach.

AI summary
Healing of wounds in mammalian tissue may be enhanced by the application of certain neuropeptides, optionally in combination with known growth promoting hormones. Exemplary neuropeptides include tachykinins, such as Substance P, Substance K, and the like, as well as calcitonin gene-related peptides. The compositions may further include a polymeric delivery carrier and are utilized by applying to the site of the wound. Wounds may be vascular or avascular wounds. The compositions promote elaboration of cellular matrices and development of cellular attachment mechanisms in addition to stimulating cellular proliferation.
