Automation plays a vital role in reducing development time in the pharmaceutical industry, both for drug substances (DS) and drug products (DP). In the last two decades, many aspects of crystallization development (solubility, kinetics, solid form characterization, concentration) have been positively impacted by automation, both in hardware and data processing. However, wet milling, a critical unit operation used to manipulate particle properties in a crystallization process, has been non-conducive for automation.
This study discusses efforts towards automation of wet milling coupled with off-the-shelf automation tools for faster execution of physical property design workflows. The hardware and software configuration used, along with challenges and prospects to achieve milling automation are discussed. Lovastatin was used as a model compound to demonstrate the capabilities of the automated platform to achieve morphology and size manipulation. The on-demand milling platform combined with data-rich trials using PAT is estimated to accelerate process development for particle engineering and reduce the drug substance delivery time to the drug product team.
