Mushroom Polysaccharide Eye Drops for Dry Eye Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic compositions fail to provide sustained relief for ocular discomfort, particularly for dry eye syndrome, and often contain preservatives that can irritate the eyes, lacking the natural benefits of the tear film.
Innovation Solution
Development of ophthalmic pharmaceutical compositions comprising polysaccharides extracted from mushrooms, specifically glucuronoxylomannan or variants, which remain on the ocular surface for an extended period, providing relief from discomfort caused by dry eye syndrome, allergies, infections, and inflammation without preservatives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preservatives are added to ophthalmic compositions to extend shelf life, then storage stability is improved, but eye irritation and harmful effects increase
Solution Approach 1:
The patent removes preservatives from the ophthalmic composition entirely, extracting the harmful substance while maintaining product stability through alternative means (sterile formulation and controlled packaging)
Solution Approach 2:
The composition is formulated as a preservative-free single-use or limited-use product, accepting shorter in-use stability in exchange for eliminating preservative-related eye irritation
2Productivity
If conventional ophthalmic compositions are used, then immediate relief is provided, but duration of action is short-lived
Solution Approach 1:
The patent changes the physical-chemical parameters of the composition by incorporating specific polymers and lipids that modify rheological properties, enabling the formulation to remain on the ocular surface longer while maintaining immediate comfort relief
Solution Approach 2:
The composition uses a composite formulation combining polymers, lipids, and buffers that work synergistically to provide both immediate relief and extended duration of action on the ocular surface
3Ease of manufacture
If artificial tear compositions are formulated without natural tear film components, then manufacturing simplicity is improved, but effectiveness in providing natural tear benefits is reduced
Solution Approach 1:
The patent modifies the formulation to include specific physiological components (polymers, lipids, buffers) that mimic natural tear film properties, enhancing effectiveness while maintaining manufacturing feasibility through well-established pharmaceutical ingredients

AI summary
A composition for providing relief to a discomfort of an eye comprises a pharmaceutically acceptable carrier and a polysaccharide extracted from a plant source. In certain embodiments, such a polysaccharide can be extracted from mushrooms, such as from the Tremella fuciformis species. The composition is administered to an affected eye to provide such relief or discomfort.
