A pharmaceutical suspension is a coarse dispersion in which the internal phase (the active ingredient) is placed/distributed uniformly throughout the external phase/continuous phase. Internal phase consists – Insoluble solid particle size of range -0.5 – 5 micrometer ;

- Classification of Suspension Based on The Size of Solid Particles
Based on the route of administration, suspensions can be classified as oral, topical, parenteral, rectal, otic or ophthalmic suspensions. These are briefly described as follows:
Based on the concentration of the dispersed phase, suspensions can be classified as dilute and concentrated suspension.
Suspensions can be classified into flocculated and deflocculated suspension based on the electrokinetic nature of the dispersed phase.
Based on the particle size (diameter) of the dispersed phase, suspensions can be classified as 1. Coarse suspension (>1 μm) 2. Colloidal dispersion (< 1 μm) 3. Nanosuspension (10–100 nm) To continue reading, click on the page buttons below…
5 days ago · What is suspension? A suspension is a dispersion of finely divided, insoluble solid particles (the disperse phase) in a fluid (the dispersion medium or continuous phase). A dispersed phase with a mean particle diameter of up to 1 um is usually termed a colloidal dispersion.
Mar 7, 2023 · Examples of some pharmaceutical suspensions: Amoxicillin Oral Suspension, Mebendazole Oral Suspension, Albendazole Oral Suspension, Natamycin Ophthalmic Suspension etc.
Aug 12, 2023 · Suspension is usually formulated for drugs that are water-insoluble or poorly soluble such as Prednisolone suspension. They are also formulated to prevent the degradation of the drug or to improve its stability as in the case of Oxy-tetracycline suspension.
Definition. A Pharmaceutical suspension is a coarse dispersion in which internal phase (therapeutically active ingredient)is dispersed uniformly throughout the external phase.
