Polymeric Matrix for Modified Release Solid Oral Preparations
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 and allowing for higher dosages and flexible administration forms, including tablets, capsules, and soluble sachets, while maintaining controlled release characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tablets and pellets with inert support cores are used, then the active substance can be delivered with modified release, but the volume increases and swallowing becomes difficult
Solution Approach 1:
The invention extracts and removes the inert support core from the traditional tablet structure, retaining only the essential functional components. The active substance is directly coated with polymeric membranes, eliminating the unnecessary inert material that increases volume without contributing to the therapeutic effect.
Solution Approach 2:
The invention uses thin polymeric membrane coatings directly on the active substance particles. These flexible film layers provide the modified release function without requiring a bulky inert core, thereby reducing the overall volume while maintaining the controlled release特性.
2Reliability
If traditional tablets with inert support cores are used, then the active substance can be delivered with modified release, but swallowing becomes difficult especially for high dosages
Solution Approach 1:
By removing the inert support core, the invention significantly reduces the physical size and bulk of the dosage form. This extraction of unnecessary material makes the tablet much easier to swallow, particularly for high dosages where traditional formulations would require large volumes.
Solution Approach 2:
The invention changes the physical parameters of the dosage form by eliminating the inert core structure. This parameter change from a core-based structure to a coated particle structure results in a compact, easily swallowable form while preserving the modified release function through the polymeric membrane.
3Reliability
If traditional tablets with 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 polymeric membrane-coated active substance particles serve multiple functions simultaneously: they provide the active substance delivery, enable modified release through the membrane, and allow for high dosages in a single unitary form. This multi-functionality eliminates the need to divide dosages into multiple units or combine separate formulations.
Solution Approach 2:
The invention merges the functions of the inert support core and the active substance delivery system into a single integrated structure. The active substance particles themselves become the structural basis, coated with functional membranes, combining what were previously separate components into one unified dosage form that can deliver high dosages without division.
4Ease of manufacture
If inert support cores are added to the active substance, then the active substance can be formulated into tablets, but the volume of the final administration form must be increased
Solution Approach 1:
The invention extracts the inert support core from the formulation, using only the active substance particles as the structural basis. This eliminates the volume contribution from inert materials while maintaining the ability to formulate into tablets through direct coating of the active substance with polymeric membranes.
Solution Approach 2:
By using thin polymeric membrane films directly on the active substance particles instead of bulky inert cores, the invention achieves tablet formulation capability with minimal volume increase. The flexible film structure provides sufficient mechanical integrity for tablet formation without the volume penalty of traditional inert supports.
