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.
