Pharmaceutical Unit Dose Metering for Accurate Component Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pharmaceutical and dietary supplement compositions face challenges in achieving consistent and accurate dosages, especially for rapid melt forms, due to the difficulty in uniformly mixing ingredients with different physical characteristics, which is crucial for pediatric, geriatric, and cancer patients who cannot swallow tablets or capsules.
Innovation Solution
A method involving individually metering and dispensing specific volumes or weights of components into a sealed container, where a thickening agent acts as a carrier for the active ingredient, allowing for precise dosing without water, and can include multiple components with taste masking and controlled release formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple solid ingredients with different physical characteristics are mixed together, then the dosage form can contain multiple active ingredients, but the ingredients tend to separate and uniform mixing becomes difficult
Solution Approach 1:
The patent segments the multi-ingredient mixture into individual unit doses, with each unit dose containing all ingredients pre-mixed in the correct proportions. This segmentation occurs at the packaging stage rather than attempting to maintain uniform mixing throughout a large batch, thereby resolving the separation issue while maintaining manufacturing efficiency.
Solution Approach 2:
The patent performs preliminary mixing and dosing of multiple ingredients into individual unit doses during manufacturing, before distribution and use. This preliminary action ensures uniform distribution of all ingredients in each unit dose, eliminating the separation problem that would occur if mixing were attempted at the point of use.
2Ease of manufacture
If traditional tablet or capsule forms are used, then the dosage form is stable and easy to manufacture, but patients who cannot swallow tablets or capsules cannot use them
Solution Approach 1:
The patent changes the physical state parameter of the dosage form from solid (tablet/capsule) to semi-solid (soft gelatin capsule or melt formulation). This parameter change makes the dosage form suitable for patients who cannot swallow traditional solid forms, while still maintaining ease of manufacture through established encapsulation or melt-filling techniques.
3Ease of operation
If water is required for administration, then the active ingredient can be properly delivered, but patients who cannot consume water cannot use the dosage form
Solution Approach 1:
The patent introduces a self-contained liquid or melt phase within the soft gelatin capsule or melt formulation that acts as an intermediary medium. This internal liquid/melt phase dissolves or carries the active ingredient, eliminating the need for external water administration while maintaining proper delivery of the active ingredient.
4Measurement precision
If individual metering and dispensing of components is implemented, then the accuracy and precision of component amounts is very high, but the manufacturing process becomes more complex
Solution Approach 1:
The patent merges the metering and dispensing operations into a single integrated unit dose filling process. Rather than separately metering each ingredient and then combining them, the process combines multiple ingredients in a single filling operation into pre-measured ratios, achieving high dosing accuracy while simplifying the overall manufacturing process.

AI summary
By individually metering and dispensing specific volumes and/or weights of each component of a dosage, an amount of the components for each dose is secured with very high accuracy. A method for dosing a pharmaceutical product in a sealed container, such as, for example, a packet, sachet, blister pack, or other unit dose form. The dosage may include a first component that is a thickening agent and a second component that is an active ingredient. The thickening agent serves as a carrier that allows the active ingredient to dissolve in the mouth and be swallowed without the administration of water. The method includes providing the first component by measuring the volume or weighing the mass of the first component and measuring the volume or weighing the mass of the second component. Subsequent components may also be individually measured or weighed before being added to a package.
