Low-Osmolality Rehydration Composition for Oral Drug Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oral administration of medications can be hindered by physical, biological, or biochemical barriers, particularly dehydration, which reduces drug absorption and therapeutic efficacy, and existing rehydration solutions with osmolality higher than blood plasma are not optimal for efficient rehydration and drug delivery.
Innovation Solution
A rehydration composition with an osmolality lower than normal blood plasma, typically between 25-275 mOsm/kg, that includes electrolytes and an active ingredient, facilitating both rehydration and efficient systemic delivery of the active ingredient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If oral rehydration solutions with high electrolyte and carbohydrate concentrations are used, then dehydration can be treated, but the osmolality exceeds that of normal blood plasma which reduces rehydration efficiency
Solution Approach 1:
The patent applies parameter changes by formulating an oral rehydration solution with specific concentration ranges: electrolytes at 2-10 mmol/L, carbohydrates at 5-20 mmol/L, and osmolality controlled at 200-300 mOsm/kg. This optimization of physical-chemical parameters ensures the solution has lower osmolality than blood plasma, creating an osmotic gradient that facilitates efficient water absorption while still providing adequate replacement of depleted substances.
2Productivity
If water alone is provided to a dehydrated patient, then hydration can be restored, but electrolytes and carbohydrates that are depleted cannot be replaced
Solution Approach 1:
The patent implements multi-functionality by designing a single oral rehydration solution that simultaneously performs multiple functions: (1) replaces depleted water through controlled osmolality, (2) replenishes electrolytes at therapeutic concentrations, (3) restores carbohydrate levels, and (4) provides energy. This universal solution integrates what would otherwise require separate administrations, making the rehydration process comprehensive and efficient.
3Reliability
If conventional oral rehydration solutions are used, then dehydration treatment is provided, but drug absorption is hindered due to dehydration barriers
Solution Approach 1:
The patent applies preliminary action by first optimizing the patient's hydration status through administration of the controlled-osmolality rehydration solution before or concurrent with drug administration. By pre-establishing proper plasma volume and reducing osmotic barriers through the optimized solution formulation, the subsequent drug absorption is facilitated. The solution prepares the physiological environment to remove dehydration-related absorption barriers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively rehydrates patients while concurrently delivering active ingredients, such as medications or nutritional supplements, by maintaining optimal osmolality for improved absorption and reducing dehydration-related barriers.
Implementation Method 1
Osmotic pressure is primarily responsible for the direction and rate of movement of water across semipermeable membranes, including semipermeable membranes in the body. Water, having an osmolality of approximately zero, can move into or out of digestive organs, blood plasma, and cells depending on the relative internal and external osmotic pressures.
