Reconstitutable Metformin Sachets for Swallowing Ease
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antidiabetic medications, particularly metformin, often come in large tablet forms that are difficult for patients to swallow, and existing liquid formulations require multiple dosing and inconvenient packaging, leading to compliance issues and stability concerns.
Innovation Solution
Development of reconstitutable, single-use antidiabetic compositions comprising metformin or its salt as an extended release composition, optionally combined with other antidiabetic agents and excipients, which are filled into sachets and reconstituted just before consumption, ensuring dose uniformity and accuracy between 95% and 105% and long-term stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If large tablet forms are used for metformin, then extended release and reduced dosing frequency are achieved, but patient compliance deteriorates due to swallowing difficulties
Solution Approach 1:
The large tablet is segmented into multiple smaller tablets or granules that can be easily swallowed. The patent describes breaking down the extended release formulation into smaller units that maintain the controlled release properties while improving patient compliance by eliminating swallowing difficulties associated with large tablets.
Solution Approach 2:
The physical form parameter is changed from large tablet to smaller tablets or granular form. This parameter change maintains the extended release functionality through controlled release mechanisms while significantly improving the ease of swallowing and patient compliance.
2Ease of operation
If liquid formulations are used for antidiabetic medications, then swallowing ease is improved, but patient compliance deteriorates due to multiple dosing requirements and inconvenient packaging
Solution Approach 1:
Multiple doses are merged into a single sachet containing a combination of granules. The patent describes combining multiple dosing units into one convenient sachet that provides extended release over several days, eliminating the need for multiple separate liquid doses and simplifying packaging to a single-use format.
Solution Approach 2:
The medication is prepared in advance as pre-measured granules in single-use sachets. This preliminary action of pre-dosing and packaging eliminates the need for patients to measure or prepare multiple doses, reducing packaging complexity and improving compliance through convenience.
3Ease of operation
If reconstitutable single-use compositions are used, then patient compliance and ease of administration are improved, but manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into separate stages: first producing the extended release granules, then filling them into single-use sachets. This segmentation of the manufacturing process into modular steps makes the complex reconstitutable single-use formulation more manageable and scalable while maintaining administration convenience.
