Polymeric Matrix for Modified Release Without Inert Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional oral administration forms of medicaments and food supplements with modified release, such as tablets and pellets, require inert support cores, leading to increased volume and swallowing difficulties, especially for high dosages, and often necessitate dividing the dosage into multiple units.
Innovation Solution
A polyvalent matrix comprising particles of active substances directly coated with polymeric membranes, eliminating the need for inert support cores, allowing for higher dosages and flexible administration forms without altering modified release characteristics, and enabling easy disintegration and taste masking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If inert support cores are used to carry active substance, then the structural integrity and handling of dosage forms is improved, but the volume of the final administration form increases leading to swallowing difficulties
Solution Approach 1:
The patent removes the inert support core from the traditional pellet structure, retaining only the active substance particles which are directly coated with polymeric membranes. This extraction of the unnecessary inert component reduces the overall volume and weight of the dosage form while maintaining the essential function of controlled release.
Solution Approach 2:
The patent merges the functions of the inert core and active substance into a single integrated structure where active substance particles themselves serve as the core. The polymeric membrane coating directly encapsulates the active substance, eliminating the need for a separate inert support layer.
2Quantity of substance
If inert support cores are used, then the active substance can be delivered, but the total dosage must be divided into several unitary doses
Solution Approach 1:
The patent creates a universal matrix system based on agglomerates of active substance particles coated with polymeric membranes that can accommodate various dosages and active substances. This multi-functional system eliminates the need for multiple different inert core types and simplifies the dosage form design while maintaining controlled release capabilities.
3Duration of action of moving object
If traditional tablets with inert components are used, then the modified release can be achieved, but the active substance titer is limited
Solution Approach 1:
The patent changes the fundamental parameters of the matrix structure from inert-core-based to active-substance-based agglomerates. This parameter change allows the active substance titer to be significantly increased since the entire volume of the agglomerate can be occupied by active substance particles rather than being diluted with inert materials.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The polyvalent matrix achieves higher dosages, flexible administration forms, and improved swallowing ease by eliminating inert cores, ensuring uniform release and taste masking, suitable for geriatric and pediatric use, while maintaining the stability and prolonged-release properties of active substances.
Implementation Method 1
release the active substance in the gastrointestinal tract according to predeterminated modes
Implementation Method 2
keep the active substance fully isolated from the outer environment
