A most important parameter in the evaluation stability of the suspension. sedimentation volume is a ratio of the ultimate volume of sediment (v u) to the original volume of sediment (v o) before settling. the sedimentation volume gives only a qualitative account of flocculation. sedimentation value: ‘ f ‘ has values ranging from less than.

Evaluation Of Suspension Pharmaceutics The Pharmapedia An oral pharmaceutical suspension presents a novel means of circumventing the potential problems associated with administration. the suspension can be easily administered to children and old age populations. [2] suspension a pharmaceutical suspension may be defined as a coarse dispersion of finely subdivided. Ingredients for formulation of suspensions. 1. api. therapeutic active substance. 2. wetting agents hlb= 7 9. added to disperse solids in the continuous phase. decrease interfacial tension between solid particles and liquid mediums. e.g. alcohol in tragacanth mucilage, glycerin in sodium alginate. Pharmaceutical suspension classifications based on a percentage of solute: based on a percentage of solute, two types of suspension in pharmacy as below: dilute suspension: suspension consists of 2 to 10% w v of solid particles. the example includes cortisone acetate suspension. concentrated suspension: suspension consists of 50% w v solid. A flocculated suspension is a suspension in which particles of the suspension has undergone flocculation. a flocculated suspension is composed of large aggregates (flocks) and this type of suspension will lead to a rapid rate of sedimentation. sedimentation is the settling down of aggregates or particles of suspension to the bottom of the liquid.

Depending on the route of administration the particle size in the suspension may vary from less than 1 μm for ophthalmic use to about 10–100 μm for dermatological use, and up to 200 μm for oral use. many of the recently discovered active pharmaceutical ingredients are quite hydrophobic with limited solubility. A pharmaceutical suspension is a coarse dispersion of insoluble solid particles in a liquid medium. the particle diameter in a suspension is usually greater than 0.5 µm. however, it is difficult.
