Solutions for Lyophilization Process
and Formulation Development
What is lyophilization?
Lyophilization, or freeze-drying, is a technique used to render biologics and large molecule drugs stable for transport and long-term storage. The pharmaceutical lyophilization process is quite complex, with a series of precisely controlled temperature and pressure steps.
Process parameters and physio-chemical properties, such as freeze-dried cake moisture content, reconstitution time, integrity, homogeneity, uniformity and potency, are often employed to confirm drug product quality as well as its stability under storage. Despite decades of collective experience, the lyophilization process remains to be time-consuming and costly in both development and manufacturing scale-up phases due to the challenges in cycle development, process optimization, and cake characterization.

Current analytical approaches lack the sensitivity and resolution to analyze these microstructure associated properties without affecting the inherent cake structure. At DigiM, we apply non-invasive X-ray microscopy (XRM), AI analytics of critical quality parameters, and image-based simulation to evaluate cake quality and mass transport properties of lyophilized materials.
