Iodine Steroid Sinus Compositions Using Cyclodextrin Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for chronic rhinosinusitis and cystic fibrosis-related sinusitis face challenges due to the incompatibility of iodine and steroid preparations, which are reactive and often require toxic preservatives, leading to ineffective delivery and potential harm, especially in patients with compromised airway function.
Innovation Solution
Development of stable pharmaceutical compositions combining iodine-containing compounds like povidone-iodine with steroids such as budesonide, fluticasone, or mometasone, which resist iodination and oxidation, allowing for synergistic treatment of sinus symptoms without causing toxic inflammatory reactions, and are formulated to be administered via nasal irrigation or spraying, effectively targeting biofilms and inflammatory responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iodine-containing compounds and steroids are combined in pharmaceutical compositions, then synergistic treatment of sinus symptoms is achieved, but chemical reactivity between iodine and steroid causes instability and potential toxicity
Solution Approach 1:
The patent uses cyclodextrin as an intermediary substance to complex with iodine-containing compounds, creating a stable inclusion complex that prevents direct chemical reaction between iodine and steroid. This mediator approach allows both active ingredients to coexist without harmful interactions while maintaining their therapeutic effects.
Solution Approach 2:
The patent creates a composite pharmaceutical composition where iodine-containing compounds, steroids, and cyclodextrin form a multi-component system. The cyclodextrin acts as a structural framework that encapsulates iodine, creating a stable composite material that combines the antimicrobial properties of iodine with the anti-inflammatory effects of steroids without chemical incompatibility.
2Stability of the object's composition
If traditional preservatives are used in iodine-steroid compositions, then stability is improved, but toxic inflammatory reactions occur especially in patients with compromised airway function
Solution Approach 1:
The patent extracts and removes traditional toxic preservatives from the formulation. Instead of using conventional preservatives like benzalkonium chloride or parabens that can cause inflammatory reactions, the invention relies on the inherent stability provided by the cyclodextrin-iodine complex and the sterile preparation method to maintain stability without harmful additives.
Solution Approach 2:
The patent employs single-use sterile packaging and preparation systems that eliminate the need for long-term preservatives. Each unit is sterilized and sealed, allowing the composition to remain stable without toxic preservatives, and the single-use nature prevents contamination and degradation over time.
3Stability of the object's composition
If iodine and steroid are administered separately, then chemical compatibility is maintained, but effective delivery and synergistic treatment are reduced
Solution Approach 1:
The patent merges iodine-containing compounds and steroids into a single unified pharmaceutical composition using cyclodextrin as a carrier. This combination allows both active ingredients to be delivered simultaneously to the target site in the sinus cavity, achieving synergistic therapeutic effects while the cyclodextrin prevents harmful chemical interactions between the components.
