Microstructures are essential in the development of pharmaceuticals. The size, distribution, and interplay of active pharmaceutical ingredients (API), excipients, and porosity are important to the therapeutic performance of a drug or a medical device.     

At DigiM, we have developed an integrated micro-imaging platform to take on challenges in drug formulation, product design, and process development. DigiM pharmaceutical microstructure characterization platform includes high resolution correlative 3D imaging, AI-based image analysis, and image-based release prediction. We analyze a wide range of pharmaceutical samples including solid dosage forms, lyophilized biologics, and combination products, from early formulation development to final products in the market stage. See the sidebar for some of the unique challenges we have solved for our customers.

Example key performance attributes for a drug product sample includes but is not limited to:

  • Microporosity
  • API Particle Size Distribution
  • Uniformity and Connectivity of API, Pore, and Excipient
  • Image Based Simulation of Physical Properties (including dissolution/release profile)
  • Geometry and Shape for Quality Control
  • Interface Characterization (including coatings)
