Bromhexine Aqueous Composition Stability and Taste Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bromhexine-containing compositions face stability issues during storage, leading to decomposition and a bitter taste, which complicates their use in film packaging and dosage forms.
Innovation Solution
An aqueous composition with bromhexine, sugar alcohols in less than 10g per 100ml, a thickener, sweetener, and other additives like preservatives and flavorings, providing a low decomposition rate and masking the bitter taste, suitable for film packaging and effective secretory therapy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If sugar alcohols are added to stabilize bromhexine-containing compositions, then the stability of bromhexine is improved, but the amount of sugar alcohols required (more than 10g per 100ml) results in increased viscosity and altered mouthfeel
Solution Approach 1:
The patent changes the concentration parameter of sugar alcohols from the conventional more than 10g per 100ml to less than 10g per 100ml. This parameter change maintains the stabilizing effect on bromhexine while avoiding excessive viscosity and preserving acceptable mouthfeel characteristics.
2Object-generated harmful factors
If high amounts of sugar alcohols (>10g per 100ml) are used to mask the bitter taste of bromhexine, then the taste masking is improved, but the composition becomes too viscous and unsuitable for certain dosage forms
Solution Approach 1:
The patent optimizes the sugar alcohol concentration parameter to less than 10g per 100ml, which provides sufficient taste masking while maintaining appropriate viscosity levels that enable film packaging and other dosage forms.
Solution Approach 2:
The patent combines sugar alcohols with other excipients (thickeners, sweeteners, preservatives) in specific amounts to create a composite composition that achieves taste masking and stability without relying on excessive sugar alcohol content alone.
3Stability of the object's composition
If reducing agents and chelating complexing agents are added to stabilize bromhexine, then the decomposition rate is reduced, but the composition complexity and number of additives increase
Solution Approach 1:
The patent extracts or removes the need for reducing agents and chelating complexing agents from the composition. By using only sugar alcohols in optimized amounts (less than 10g per 100ml), the patent achieves stable bromhexine without these additional stabilizing agents, thereby simplifying the composition.
