Abstract
Nanomedicines are an advanced class of drug formulations that hold significant promise, particularly in enhancing the solubility of hydrophobic drugs. However, current state-of-the-art methodologies for developing nanomedicines are often inefficient, limiting both the systematic screening of dosage forms and the fine-tuning of individual formulations. To overcome these challenges, this study introduces a data-driven workflow that integrates active learning with experimental automation to rapidly identify optimal nanoformulations, using aceclofenac as a model poorly soluble drug. The initial formulation design space comprised combinations of the drug with 12 different excipients, resulting in approximately 17 billion possible formulations. To optimize across four objectives simultaneously, the active learning–robotic system efficiently narrowed this vast space to a manageable subset. This refined subset was further explored using a design of experiments approach, with selected formulations manually prepared and subjected to standardized evaluation. Within weeks, a panel of high-performing lead nanoformulations was identified. Notably, several of these promising formulations represent hybrid nanomedicines that are not well studied in the literature. These findings highlight the power of combining AI-driven design with automation to accelerate nanomedicine development and lay the groundwork for more efficient formulation development.
