8:30 Opening Keynote: Strategies Of Maximizing Exposure Of Water-Insoluble Drugs In Toxicology Evaluation And Early Formulation Development

Compounds optimized solely on the basis of receptor-based potency are usually hydrophobic and as a result, more than 40% of newly discovered drugs or NCEs are poorly water soluble or water-insoluble. In toxicological evaluation for waterinsoluble drug candidates, maximizing the systemic exposure of these drug candidates is very critical, though the approach of solubilizing the drug in toxicological evaluation may not be relevant to the approach used for the final finished product. This session will discuss some commonly and less commonly used solubilization techniques in the toxicological formations.

  • Approaches of maximizing exposure
    • Solution
    • Liquid dispersions
    • Solid dispersion/nanocrystal/amorphous
    • Suspension
  • Categorize “conventional” and “non-conventional” approaches
    • Accessibility/ convenience.- pH adjustment, micelles, lipid based and selfemulsifying systems, complexation, and co-solvents
    • Dissolution limited vs solubility limited – liposomes, polymeric micelles, emulsion/ microemulsion/ self-emulsifying systems, some micellar systems, and complexation
    • Low dose vs high dose: all the methods needed to try to increase solubility
  • Vehicles to be considered; Interaction with membrane, toxicity/acceptability in humans, physical phenomena e.g., precipitation in GI fluid
