Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drug delivery methods using solvents often result in toxic side effects and irritations, limiting the effectiveness of active compounds due to interactions with the extracellular matrix, particularly after subcutaneous administration, which reduces drug uptake and kinetics.
Innovation Solution
The use of novel ionic liquids comprising a quaternary ammonium cation with specific anions such as carboxylic acids like maleic acid or propanoic acid, which reduce matrix interaction, enhancing drug delivery kinetics by facilitating quicker and more efficient entry of drugs into the bloodstream.

Engineering Contradiction Analysis
1Productivity
If conventional solvents are used for drug delivery, then drug uptake can be improved, but toxic side effects and irritation occur
Solution Approach 1:
The patent changes the chemical parameters of the delivery vehicle by using ionic liquids with specific compositions (quaternary ammonium cations combined with specific anions) instead of conventional solvents. This parameter change allows achieving improved drug uptake while avoiding the toxic side effects associated with traditional solvents.
Solution Approach 2:
The invention employs composite ionic liquid formulations combining specific cations and anions in defined ratios to create a delivery system that simultaneously provides enhanced drug uptake and eliminates toxicity. The composite nature of these ionic liquids allows optimization of both efficacy and safety profiles.
2Productivity
If solvents are used to deliver active compounds, then uptake is improved, but interactions with extracellular matrix reduce effectiveness
Solution Approach 1:
The ionic liquids act as intermediary carriers that facilitate drug delivery through the extracellular matrix without causing harmful interactions. These ionic liquid mediators enable the active compounds to reach their target effectively, improving both uptake and overall delivery reliability.
3Productivity
If first-generation ionic liquids are used, then some delivery improvement is achieved, but suboptimal kinetics are observed
Solution Approach 1:
The patent optimizes delivery kinetics by changing the compositional parameters of ionic liquids, specifically selecting particular quaternary ammonium cations and anions with defined pKa and Log P values. This precise parameter optimization achieves superior kinetics compared to first-generation ionic liquids.
Solution Approach 2:
The invention creates dynamically optimized ionic liquid formulations where the cation-anion combinations are specifically selected to achieve optimal delivery kinetics. The dynamic adjustment of ionic liquid composition allows for enhanced drug release and uptake rates compared to static first-generation formulations.
