Study Notes

Suspension Characteristics

  • The dispersion medium for coarse suspensions is typically a liquid, which can be water or a non-aqueous solvent.
  • Deflocculated suspensions are characterized by individual particles or very small aggregates, which are dispersed throughout the dispersion medium.

Coarse Suspensions

  • The dispersed phase in coarse suspensions is composed of large, visible particles that settle out of the dispersion medium over time.

Formulation for Unstable Drugs

  • Suspensions are formulated for non-stable drugs to improve their stability and solubility.

Role of Pharmaceutical Excipients

  • Pharmaceutical excipients play a crucial role in suspensions as they help to stabilize the dispersed phase, prevent settling, and improve the overall physical and chemical stability of the suspension.
