Preformulation Solutions

Understanding the physical properties of your API is a critical first step in preparing for the technical challenges one may expect to encounter as the development journey begins.

With state-of-the-art equipment and world-class scientific experience, CoreRx Pharma can efficiently analyze your drug substance to elucidate potential paths for development.

In our hands, each analysis will generate important information concerning your molecule. We will then incorporate this data into our proprietary, early-assessment biomodel and perform a risk assessment with guidance for next steps in formulation and process toward a commercializable oral dosage form.

Based on this guidance, we can work together to define the next bodies of work to efficiently progress your program toward clinical studies in whatever technological path is subscribed.
