Predictive Accelerated Stability 

  • Primera will work with you to design a predictive accelerated stability study to assist with your understanding of your formulations and their stability.

API-Excipient Compatibility

  • Screening of excipient and API compatibility is encouraged by (ICH) Q8 and Quality by Design (QbD) principles.
  • Primera will work with you for an understanding of the interactions between the API and the formulation components.
  • Changes in the physical, chemical and therapeutic properties of the API will be studied.

Particle Size Distribution

  • Primera will utilize particle size instrumentation such as the Mastersizer 3000 and Zetasizer Nano to assist you with your formulation development.

Polymorph Studies

  • Primera will use X-Ray Diffraction to help characterize the API and drug product through-out the drug development process.

Differential Scanning Calorimetry (DSC)

  • DSC is a common thermal platform that is utilized for testing excipient incompatibilities. Primera has this technology and can utilize this to assist you in your determination of the optimal API-Excipient combination.
