This research proposal outlines a comprehensive and systematic approach to advancing the understanding and application of co-amorphous solids for enhancing stability and solubility, thereby improving drug delivery. By meticulously addressing critical challenges related to physical instability, phase separation, scalability, and mechanical performance, this project aims to bridge the current gaps between molecular design and pharmaceutical applicability. The work explains a systematic procedure that includes: • Selection of Model Drugs and Co-formers: Prioritizing APIs with stability and solubility issues, representing diverse chemical properties, and selecting co-formers from various chemical classes based on their predicted interaction capabilities. • Development of Binary and Ternary Co-amorphous Solids: Exploring both binary (API + co-former) and ternary systems (API + co-former + polymer) to enhance stability, reduce moisture sensitivity, and improve processability. • Preparation Methods: Investigating and optimizing mechanical activation (ball milling, co-grinding), thermal processing (melt quenching, hot-melt extrusion), and solvent-based techniques (spray drying, freeze-drying, electrospinning) to ensure single-phase amorphous state formation while preserving physicochemical integrity. • Material Characterization: Utilizing techniques such as Powder X-ray Diffraction (PXRD), Fourier Transform Infrared (FTIR) Spectroscopy, Raman Spectroscopy, Solid-State Nuclear Magnetic Resonance (ssNMR) Spectroscopy, Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA) to confirm amorphous state, identify intermolecular interactions, assess homogeneity, and monitor stability under various conditions. • Mechanical Property Studies: Employing nanoindentation to precisely measure mechanical properties like hardness and elastic modulus, which are crucial for successful processing into solid dosage forms. • Evaluation of Solubility and Dissolution Behavior: Assessing equilibrium solubility and non-equilibrium dissolution behavior under physiological conditions to establish the pharmaceutical advantage of CAMs. The systematic investigation of structure-property relationships, combined with biopharmaceutical assessments, will culminate in the identification and optimization of robust, scalable co-amorphous formulations. Ultimately, the successful execution of this research is anticipated to yield innovative co-amorphous drug delivery platforms with enhanced supersaturation, long-term stability, and improved bioavailability. These outcomes hold significant promise for expediting the development of novel drug products, thereby contributing substantially to pharmaceutical research.
