Naloxone Composition With Magnesium Chloride for Rapid Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pharmaceutical compositions for treating opioid overdose suffer from a lag time in achieving therapeutic levels due to slow absorption, which can lead to inadequate treatment and potential morbidity or mortality.
Innovation Solution
A parenteral pharmaceutical composition comprising naloxone or a pharmaceutically acceptable salt thereof, combined with magnesium chloride as an absorption-enhancing adjuvant, to enhance systemic absorption and achieve rapid onset of action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intramuscular or subcutaneous injection of naloxone is used to treat opioid overdose, then the antidote can be administered effectively, but there is a lag time before therapeutic levels are achieved due to slow absorption
Solution Approach 1:
The patent changes the physical-chemical parameters of the naloxone formulation by incorporating magnesium chloride and adjusting pH to between 3.5 and 5.5, creating a microsphere formulation that enables rapid absorption while maintaining reliability of treatment
Solution Approach 2:
The patent uses a composite material system consisting of naloxone combined with magnesium chloride in a microsphere formulation, where the composite structure provides both rapid absorption and sustained therapeutic effect, resolving the contradiction between speed and reliability
2Reliability
If conventional naloxone formulations are administered, then opioid overdose can be treated, but the onset of action is delayed which may result in inadequate treatment
Solution Approach 1:
The patent modifies key formulation parameters including pH (3.5-5.5), ionic strength, and composition by incorporating magnesium chloride to create a formulation that achieves rapid onset of action within minutes while ensuring adequate and reliable treatment of opioid overdose
Solution Approach 2:
The patent introduces magnesium chloride as an intermediary substance that facilitates rapid absorption of naloxone, acting as a mediator between the administered antidote and the bloodstream to achieve both speed and reliability of treatment
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 provides a quicker onset of action and superior pharmacokinetics, with a time to maximum plasma concentration of naloxone in 12 minutes or less, significantly reducing the risk of morbidity and mortality from opioid overdoses.
Implementation Method 1
an adjuvant that promotes, augments, or quickens the systemic absorption rate of the naloxone post intramuscular or subcutaneous injection
