Upon completion of this exercise, you should be able to:

  • Define and describe the physical characteristics of pharmaceutical suspensions.
  • Define flocculation and aggregation.
  • Identify a stable (flocculated) suspension, by visual inspection or by verbal description of its appearance and physical characteristics.
  • Describe the effect of viscosity on the sedimentation rate of suspensions.
  • Identify/describe the role of formulation aids in the preparation of suspensions. (e.g., electrolytes, viscosity enhancers).
