Pharmaceutical AI Integration
Artificial Intelligence (AI) models, particularly supervised learning algorithms like K-Nearest Neighbors (KNN) and its ensemble variants (AdaBoost-KNN, Bagging-KNN), are revolutionizing pharmaceutical research and development. Their ability to predict complex physicochemical properties, such as drug solubility under varying conditions, significantly accelerates the optimization of continuous manufacturing processes. This paradigm shift minimizes reliance on extensive experimental trials, leading to substantial cost and time savings while enhancing product quality and consistency through data-driven insights. The application of meta-heuristic optimizers like Golden Eagle Optimizer (GEOA) further refines these models by tuning hyperparameters, ensuring peak predictive performance tailored to specific pharmaceutical challenges.
Supercritical Fluid Technology
Supercritical fluid (SCF) technology, particularly using CO2-SCF, is an eco-friendly and efficient method for particle generation and nanonization in pharmaceutical manufacturing. Its advantages include low toxicity, non-flammability, affordability, and minimal waste. SCFs offer a superior approach for enhancing drug solubility and bioavailability by producing nano-sized particles with higher surface energy. This study specifically applies SCF principles to Letrozole, a poorly water-soluble drug, demonstrating how controlled temperature and pressure in a CO2-SCF system can drastically improve its dissolution characteristics. Understanding the interplay of these parameters is crucial for optimizing particle size and morphology, a key factor in drug delivery and efficacy.
Letrozole Solubility Prediction
Letrozole (LET), an aromatase inhibitor for breast cancer treatment, has limited water solubility, posing challenges for oral bioavailability. This research focuses on predicting LET solubility in supercritical CO2 using advanced machine learning models. By correlating temperature and pressure, the models provide highly accurate predictions, exemplified by AdaBoost-KNN's R-squared of 0.9945. This predictive capability is vital for designing efficient supercritical fluid processing parameters, such as rapid expansion, which can generate nanosized LET particles with enhanced solubility. The analysis of 2D and 3D plots further elucidates the complex, non-linear relationship between temperature, pressure, and LET solubility, guiding the selection of optimal operational conditions to maximize drug dissolution.
