Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional layered tablets for magnesium release do not achieve optimal release profiles, leading to concentration peaks and undesirable side effects, and there is a need for improved dietary supplements that provide targeted and reduced side effects.
Innovation Solution
A method for producing a layered tablet with a first layer releasing Mg2+ ions more quickly than a second layer, using specific magnesium salts, vitamins, disintegrants, and carriers, where the mixtures are processed through wet granulation and pre-pressing to achieve a defined hardness and release profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional layered tablets use the same pressing tool for each pressing, then the manufacturing process is simple, but the layers acquire a characteristic shape that may affect release uniformity
Solution Approach 1:
The patent divides the pressing operation into two distinct stages using two different pressing tools: a first pressing tool that creates a biconvex shape, and a second pressing tool that creates a flat surface. This segmentation allows each tool to be optimized for its specific function, improving both layer shape consistency and release uniformity while maintaining manufacturing simplicity through a standardized two-step process.
2Ease of operation
If a single dose is used to replace multiple doses, then patient compliance improves, but concentration peaks may occur leading to side effects
Solution Approach 1:
The tablet is divided into two distinct layers with different release characteristics: a first layer designed for rapid release to provide an initial therapeutic effect, and a second layer for sustained release to maintain therapeutic levels over time. This segmentation enables a single dose to replace multiple doses while avoiding concentration peaks through controlled, staggered release of the active ingredient.
Solution Approach 2:
The patent changes the release parameters of different layers by using different compositions and structures. The first layer uses ingredients and formulation characteristics that enable rapid disintegration and release, while the second layer uses ingredients and formulation characteristics that enable sustained release over an extended period, thereby maintaining steady drug levels and preventing concentration peaks.
3Speed
If rapid release formulation is used for initial dose, then optimal values are reached quickly, but concentration peaks occur causing side effects
Solution Approach 1:
The patent segments the total dose into two separate layers with distinct release profiles. The first layer is formulated for rapid release to quickly achieve optimal therapeutic values, while the second layer is formulated for sustained release to maintain therapeutic levels without creating concentration peaks. This segmentation allows the system to benefit from both rapid onset and sustained effect without the harmful effects of peak concentrations.
