Chewable AREDS Eye Health Formulation for Dysphagia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals at risk for age-related visual impairments such as Age-Related Macular Degeneration (AMD) and cataracts often face challenges with dysphagia, making traditional oral supplementation less effective due to swallowing difficulties, and existing formulations may not optimize taste and texture for an aging population.
Innovation Solution
Development of a chewable AREDS formulation without beta-carotene and with a reduced zinc content, designed to improve texture, mouthfeel, and overall taste preferences, enhancing compliance and efficacy for individuals prone to dysphagia, using natural fruit flavors like strawberry, raspberry, or blueberry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional oral supplementation is used, then the formulation can deliver the required nutrients, but it is difficult for individuals with dysphagia to swallow
Solution Approach 1:
The patent transforms the physical state of the supplement from a swallowable tablet to a chewable lozenge that dissolves in the mouth, eliminating the need for swallowing while maintaining nutrient delivery through prolonged contact with oral mucosa
2Quantity of substance
If the formulation includes standard zinc content, then it provides adequate nutritional supplementation, but it creates unpleasant taste and aftertaste
Solution Approach 1:
The patent reduces zinc content from standard levels to a optimized range that maintains therapeutic effectiveness while minimizing metallic aftertaste and improving overall palatability for frequent dosing
Solution Approach 2:
The patent introduces flavoring agents and binding materials as intermediaries that mask the metallic taste of zinc and create a pleasant sensory experience, enabling acceptance of the supplement in the chewable format
3Quantity of substance
If beta-carotene is included in the formulation, then it provides antioxidant benefits, but it interferes with the absorption of lutein and zeaxanthin
Solution Approach 1:
The patent removes beta-carotene from the formulation to eliminate its interfering effect on lutein and zeaxanthin absorption, while maintaining antioxidant benefits through the remaining carotenoids and other antioxidants in the AREDS formula
4Ease of operation
If the formulation is made chewable with natural flavors, then it improves compliance for individuals with dysphagia, but it increases formulation complexity
Solution Approach 1:
The patent uses flavoring agents and binding materials that serve multiple functions: improving taste and aroma for compliance, providing structural integrity for the chewable lozenge format, and facilitating controlled dissolution in the oral cavity

AI summary
Risk of visual impairment including Age-Related Macular Degeneration (AMD) and cataracts increase with age. This increased risk can be caused by changes in the structure and function of the eye or changes in structures of the central nervous system that support visual perception. The present invention comprises fruit flavored, chewable formulations of supplements for reducing the risk of AMD. Chewable dosage forms of the invention are preferred over other formulations and may increase compliance in an aging population, who are more likely to require an eye health supplement and have an increased risk of experiencing dysphagia.
