Preformulation Analysis

Preformulation studies on a new drug substance are the foundation of developing a robust, safe and effective drug product formulation. The investigation will generate information on the physicochemical properties of the substance that will allow the formulator to:

Increase Stability-physical and chemical                                               

Enhance Bioavailability-solubility/permeability

Improve compatibility- with excipients and in the processing environment

Scientists at CPES can perform a range of investigations including: 

 Screening for Optimised Solid Form

  • Salts
  • Solvates and hydrates
  • Polymorphs
  • Amorphous Forms
  • Co-crystals‌

Solubility Studies

  • Solubility
  • Dissolution rates
  • Partition Coefficient  (Log P)
  • pKa Solubility profiles
  • Common Ion effects

SMS Surface Energy Analyser Stability Cabinet

Bulk Powder Properties

  • Particle Size/Morphology
  • Surface Area and Surface Energy
  • Hygroscopicity
  • Powder Flow Properties
  • True Density

Stability Studies

  • Solid State Stability
  • Solution Stability
