Orally Disintegrating Tablet Bitterness Masking and Hardness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orally disintegrating tablets face challenges in achieving suitable hardness and rapid disintegrability while maintaining palatability, often requiring high compression forces that can lead to tableting failure and delayed disintegration.
Innovation Solution
The formulation includes granules A with erythritol and crystalline cellulose, and granules B with a drug and film-coating layer, combined with anhydrous calcium hydrogen phosphate and crystalline cellulose, to create an orally disintegrating tablet that can be tableted at lower compression forces, ensuring suitable hardness and rapid disintegration without bitterness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high compression force (15 kN or higher) is applied during tableting, then tablet hardness is improved, but disintegration time is delayed and tableting failure occurs
Solution Approach 1:
The invention changes the physical-chemical parameters of the formulation by incorporating specific excipients (crystalline cellulose, anhydrous calcium hydrogen phosphate, sugar alcohols) and controlling particle size parameters (700 μm or less for film-coated granules, specific size ranges for other excipients) to achieve both adequate hardness and rapid disintegration without requiring high compression forces
Solution Approach 2:
The invention uses a composite formulation combining film-coated granules (700 μm or less) with specific excipients (crystalline cellulose, anhydrous calcium hydrogen phosphate, sugar alcohols, disintegrants, lubricants) in defined proportions to create a tablet that achieves both hardness and rapid disintegration through synergistic effects of multiple materials
2Strength
If high compression force is applied during tableting, then tablet hardness is improved, but tableting failure occurs
Solution Approach 1:
The invention modifies formulation parameters by selecting specific excipients and their proportions, controlling particle size of film-coated granules to 700 μm or less, and optimizing the composition ratio of crystalline cellulose, anhydrous calcium hydrogen phosphate, sugar alcohols, disintegrants, and lubricants to enable tableting at reduced compression forces without failure
Solution Approach 2:
The invention employs a composite material system where film-coated granules are combined with specific excipients in defined ratios to create a formulation that is both moldable at low compression forces and produces hard tablets, eliminating tableting failure while maintaining hardness
3Object-affected harmful factors
If film coating is applied to mask bitterness, then palatability is improved, but uniform coating requires spherical core particles of uniform particle size
Solution Approach 1:
The invention controls the particle size parameter of film-coated granules to 700 μm or less and uses specific excipients with defined particle size ranges to achieve uniform coating formation, which masks bitterness while simplifying the coating process requirements
