Formulation Of Pharmaceutical Suspension The Pharmapedia 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. 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.
Formulation Of Pharmaceutical Suspension The Pharmapedia 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. During the formulation of suspensions selection of excipients are depended on the nature of api (active pharmaceutical ingredients) and the proposed delivery form either prepared pharmaceutical suspension or dry powder for suspension. the core ingredients for a pharmaceutical suspension are active pharmaceutical ingredients, suspending agents. Pharmaceutical suspensions, from formulation development to manufacturing provides the reader with a broad overview of suspension drug product technology. individual chapters in this book focus on. 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.

Development of stable suspensions over the shelf life of the drug product continues to be a challenge on many fronts. a good understanding of the fundamentals of disperse systems is essential in the development of a suitable pharmaceutical suspension. the development of a s pension dosage form follows a very complicated path. Lid–liquid suspensions in aqueous medium.a pharmaceutical suspension is a coarse dispersion of i. soluble solid particles in a liquid medium. the particle diameter. in a suspension is usually greater than mm. however, it is difficult and also impractical to impose a sharp boundary between the suspensions.
