Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Afabicin formulations face issues with incomplete disintegration and poor dissolution, leading to inadequate oral bioavailability and therapeutic efficacy, and require improved chemical stability and manufacturing efficiency.
Innovation Solution
The development of pharmaceutical compositions containing Afabicin, preferably in the form of Afabicin Olamine, with histidine compounds, along with specific excipients such as povidone and mannitol, to enhance disintegration, dissolution, and stability, using a manufacturing process involving dry mixing, granulation, and compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If commonly employed excipient materials are used in Afabicin formulation, then the formulation can be manufactured easily, but incomplete disintegration and poor dissolution occur
Solution Approach 1:
The patent changes the chemical composition parameters by introducing histidine compound as a key excipient at specific concentrations (0.1-10% w/w). This parameter change resolves the contradiction by improving dissolution characteristics while maintaining ease of manufacture through conventional formulation processes.
Solution Approach 2:
The patent creates a composite excipient system combining histidine compound with other pharmaceutically acceptable excipients (binders, disintegrants, lubricants). This composite approach enhances dissolution and disintegration performance while preserving manufacturability through standard pharmaceutical processing.
2Ease of operation
If Afabicin formulation is designed for oral administration, then the drug can be administered conveniently, but chemical stability and dissolution stability become problematic
Solution Approach 1:
The histidine compound acts as an intermediary substance that mediates between the drug substance and the gastrointestinal environment. It protects Afabicin from degradation while facilitating dissolution, thus resolving the contradiction between oral administration convenience and chemical stability.
Solution Approach 2:
The formulation incorporates stabilizing excipients including histidine compound that provide beforehand protection against chemical degradation during storage and gastrointestinal transit. This prior cushioning ensures stability is maintained throughout the oral administration process.
3Reliability
If Afabicin formulation achieves complete disintegration, then dissolution is improved, but manufacturing complexity increases
Solution Approach 1:
The histidine compound serves multiple functions simultaneously: it acts as a disintegrant to ensure complete tablet breakdown, provides chemical stability, and enhances dissolution. This multi-functionality achieves complete disintegration without increasing formulation complexity.
Solution Approach 2:
The patent merges the disintegrant function with stabilizing and dissolution-enhancing functions into a single excipient system centered on histidine compound. This consolidation achieves complete disintegration while simplifying the overall formulation rather than adding complexity.
