Effervescent Granules Water Control Gum Cohesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing effervescent granules face challenges in maintaining stability and integrity due to the initiation of effervescence reactions during formulation, leading to loss of effervescence over time, especially when water is present, and conventional solutions like increasing effervescence agents or dry preparation methods are not effective for all compositions.
Innovation Solution
Incorporating a biocompatible gum and controlled amounts of water (1.0 to 50 mg per g of granules) with effervescence-generating compounds, such as acid and carbonate sources, to enhance cohesion and stability, while using non-aqueous solvents like isopropyl alcohol for granulation, which counters the conventional wisdom against using water-soluble gums.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If water is present during formulation stages, then granules gain cohesion and integrity, but effervescence reaction is initiated and effervescence is lost over time
Solution Approach 1:
The gum is incorporated into the granules during the formulation stage, but its water-soluble binding action is delayed until the product is ready for use. The gum remains dormant in the dry granule structure and only activates when water is added at the point of administration, thus providing cohesion when needed without triggering premature effervescence
Solution Approach 2:
The water-soluble gum acts as an intermediary substance that bridges the contradiction between needing water for cohesion and avoiding water for effervescence stability. The gum absorbs water selectively to provide binding, while the effervescence-generating compounds remain separated and only react when the granule structure breaks down in the aqueous environment of the body
2Stability of the object's composition
If effervescence agents are increased to compensate for loss, then effervescence is maintained at the end of conservation, but the quantity of effervescence agent becomes excessive compared to other constituents
Solution Approach 1:
The patent converts the harmful effect of water (which triggers unwanted effervescence during storage) into a beneficial effect by using water-soluble gums that only provide their binding function when water is present. The same water that causes the problem during storage becomes the trigger for the desired cohesion at the point of use, eliminating the need to add excessive effervescence agents
3Stability of the object's composition
If granules are prepared dry to avoid effervescence, then effervescence stability is improved, but granules lack sufficient cohesion and return to powder form
Solution Approach 1:
The patent changes the solubility parameter of the binding agent by selecting water-soluble gums. These gums remain inactive in the dry state, allowing granules to be formulated without premature binding, but become soluble and active when exposed to water during use, providing the necessary cohesion at the appropriate time
