LSD Crystalline Salt Forms for Stability and Bioavailability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LSD formulations lack optimization due to the lack of evaluation of various polymorphic forms, which can affect stability, solubility, and bioavailability, hindering their therapeutic effectiveness for mental health treatments.
Innovation Solution
Identification and characterization of polymorphic forms of lysergic acid diethyl amide (LSD) in crystalline salt forms, including specific acid salts and their hydrates, solvates, and co-crystals, characterized by X-ray powder diffraction, differential scanning calorimetry, and other methods, to enhance stability and bioavailability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LSD is formulated without evaluating polymorphic forms, then formulation development is simpler and faster, but stability, solubility, and bioavailability are compromised
Solution Approach 1:
The patent applies preliminary action by conducting polymorph screening and characterizing crystal forms before final formulation development. This upfront evaluation of solid-state properties prevents later stability issues and ensures optimal bioavailability, while the complexity is managed through systematic screening protocols
2Stability of the object's composition
If polymorphic forms are identified and characterized, then stability and bioavailability improve, but formulation development time and complexity increase
Solution Approach 1:
The patent systematically varies crystallization parameters (solvent type, temperature, pH, concentration) to generate and characterize different polymorphic forms. This structured approach to parameter changes efficiently identifies stable forms with optimal properties, balancing thorough evaluation with reasonable development timelines
3Ease of operation
If crystalline salt forms are used, then handling and processing improve, but solubility and dissolution rates may be reduced
Solution Approach 1:
The patent selects specific crystalline salt forms with localized properties optimized for different stages: highly crystalline forms for stable handling and storage, while surface modifications or eutectic mixtures may be used to enhance dissolution rates when needed, achieving both handling ease and adequate solubility
