Co-Processed Excipients for Feeder-Limited Tablet Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous manufacturing of solid pharmaceutical dosage forms is limited by the number of feeders on devices, typically to four to six, necessitating the use of pre-blends of multiple excipients, which is economically inefficient.
Innovation Solution
The use of co-processed excipients, which combine the functionalities of multiple single excipients, allows for simplified compositions with fewer components, enabling efficient continuous manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pre-blends of multiple excipients are used to overcome feeder limitations, then the number of excipients can be increased, but economic efficiency deteriorates
Solution Approach 1:
The patent combines multiple excipient functionalities into a single co-processed excipient material. This merging approach allows the formulation to include multiple excipient functions (such as filler, disintegrant, lubricant) without requiring multiple separate feeders or pre-blend steps, thereby maintaining economic efficiency while overcoming feeder limitations.
Solution Approach 2:
The patent employs co-processed excipients that perform multiple functions simultaneously. A single co-processed excipient can provide filling, disintegration, lubrication, and flow properties, making it a universal material that replaces multiple single-function excipients. This multi-functionality resolves the contradiction by allowing diverse formulation requirements to be met without increasing the number of feeders or pre-blend operations.
2Device complexity
If the number of feeders is limited to four to six, then device complexity is reduced, but the number of excipients that can be used is restricted
Solution Approach 1:
Co-processed excipients serve as universal materials that can fulfill multiple excipient roles within the limited feeder capacity. By designing excipients with multi-functional properties, the system maintains adaptability for complex formulations without requiring additional feeders, thus resolving the contradiction between device simplicity and formulation versatility.
Solution Approach 2:
The patent changes the functional parameters of excipients by creating co-processed materials with enhanced or multiple properties. Instead of adding more feeders to handle separate excipients, the approach modifies the excipient materials themselves to provide multiple functions, thereby maintaining device simplicity while expanding formulation capabilities.
3Productivity
If compositions are simplified to use fewer excipients, then continuous manufacturing efficiency is improved, but composition functionality may be reduced
Solution Approach 1:
The patent resolves this contradiction by creating co-processed excipients with multi-functional properties. These materials can perform multiple excipient functions (filler, disintegrant, lubricant, flow agent) simultaneously, allowing simplified compositions with fewer material components to maintain full formulation functionality while improving continuous manufacturing efficiency.
Solution Approach 2:
The patent uses composite excipient materials created through co-processing techniques. These composite materials integrate multiple functional components at the material level, enabling simplified formulations to deliver comprehensive functionality. The composite nature of co-processed excipients allows fewer material inputs to achieve the same or better performance compared to traditional multi-component systems.
