SARM Microparticle Formulation for Sustained Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pain management therapies for chronic musculoskeletal pain are often associated with negative side effects, poor adherence due to daily administration requirements, and fluctuations in drug plasma levels, leading to subtherapeutic or toxic concentrations.
Innovation Solution
Development of a Select Androgen Receptor Modulator (SARM)-loaded microparticle formulation using a biodegradable polymer like PLGA for sustained release, providing long-acting pain relief with reduced administration frequency and improved adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If daily administration of SARM is used, then pain relief is maintained, but patient adherence deteriorates and treatment compliance decreases
Solution Approach 1:
The patent divides the drug delivery system into microparticles containing SARM encapsulated within a biodegradable polymer matrix. This segmentation allows the drug to be released gradually over time rather than requiring daily administration, thereby improving patient adherence while maintaining pain relief consistency.
Solution Approach 2:
The patent employs preliminary action by pre-encapsulating the SARM within the microparticle formulation before administration. This pre-prepared formulation then provides sustained release over time, eliminating the need for daily patient action and improving compliance while maintaining therapeutic effectiveness.
2Reliability
If repeated oral administration of SARM is used, then pain management is achieved, but drug plasma levels fluctuate leading to subtherapeutic or toxic concentrations
Solution Approach 1:
The patent ensures continuity of useful action through sustained release formulation. The biodegradable polymer matrix continuously releases SARM from the microparticles over an extended period, maintaining stable plasma concentrations and eliminating the fluctuations associated with repeated oral administration, thereby improving both pain management reliability and drug level stability.
Solution Approach 2:
The patent utilizes parameter changes by controlling the biodegradation rate of the polymer matrix through selection of appropriate polymer materials and molecular weights. This parameter control enables sustained release of SARM, maintaining stable plasma levels and avoiding subtherapeutic or toxic concentrations while ensuring effective pain management.
3Reliability
If daily dosing frequency is increased, then therapeutic effect is maintained, but treatment complexity and patient burden increase
Solution Approach 1:
The patent applies dynamics by designing a time-dependent release system where the microparticles gradually degrade and release SARM over weeks. This dynamic release profile maintains therapeutic effect without requiring frequent administration, reducing patient burden and simplifying the treatment regimen while preserving therapeutic reliability.
