Providing the most stable crystalline form

RTP_SolidState_0112 v2

Each solid-state form of an API has unique physicochemical properties that can have a profound impact on bioavailability, stability, and manufacturability. By discovering and characterizing their diversity of solid-state forms, it becomes possible to select an optimal form that displays an appropriate balance of properties that is critical for successful preclinical evaluation and product development, as well as robust manufacturing processes.  

Identification of the optimal solid-state form for development relies on several factors:

  • A clear understanding of the target attributes of the API and drug product
  • Design and execution of an appropriate screen to produce solid-state forms of importance
  • Detailed evaluation of relevant solid-state forms
  • Assessment of the risk-benefit profile of the candidate solid-state forms against the target attributes.  

Catalent has recently introduced OptiForm® API - a state-of-the-art solid-form screening service that can efficiently and effectively address all of these objectives. It combines industry-proven workflows and an experienced scientific workforce with high-throughput platform technologies to provide customers with a rapid and material-efficient route to solid-form discovery and selection.
