The first step for recipe optimization is thermally characterizing the product (Active Pharmaceutical Ingredient together with the excipients). Differential Scanning Calorimetry (DSC) for the glass transition temperature and/or the Eutectic point. Cryogenic microscopy for the collapse temperature.
Then also it is required the evaluate the efficacy of the process and evaluate the drug potency before and after the lyophilization: Stability, residual Humidity by Karl Fisher, PH, gases chromatographpy, flow cytometry, protein analysis and mesenchymal growth.
Freeze drying cycles lasts between one and three days (sometimes even more). Complementary to experimental trials is crucial to thermodynamically simulate the process.
Primary drying simulation tool: full information of tempererature profile during the primary drying. Customizable including: trays with vials, protective membranes; time and filling height optimization.
Freezing step simulator: ramp rates at the product with precooled shelves, freezing times including phase change.
It can be integrated to production optimization tools.
