What are diffusible suspensions?
Suspension containing diffusible substances • They contain easily dispersible solids • They are light and easily wettable substances • Readily mixed with water and on shaking diffuse evenly throughout the liquid long enough to ensure even distribution and a dose to be measured 9.
Which of the following is a diffusible solids?
Examples of diffusible solids: Bismuth carbonate, light kaolin, magnesium oxide, magnesium carbonate, magnesium trisilicate etc.
What is the size of particle in suspension?
Suspensions may be defined as preparations containing finely divided drug particles (between 1 and 50 micrometers in diameter) distributed uniformly throughout a fluid or semisolid vehicle. These particles are large enough to sediment under the influence of gravity.
How dispense suspension contains Indiffusible solid?
Method of dispensing: Mix rinsing of mortar and pestle and add other liquid ingredient make up the volume by adding vehicle and mix properly by shaking the final product. Store in suitable container with label having ‘shake well before use’ instruction and dose.
How will you dispense mixture containing precipitate forming liquid?
• Mixture containing precipitate forming liquid :- To prevent this compound tragacanth powder or tragacanth mucilage are used. The insoluble portion of slightly soluble liquids is not readily diffusible. So a suspending agent is needed to dispense such mixture.
What are the examples of pharmaceutical suspension?
Examples of Pharmaceutical Suspensions
- Antacid oral suspensions Antibacterial oral suspension.
- Dry powders for oral suspension (antibiotic)
- Analgesic oral suspension.
- Anthelmentic oral suspension.
- Anticonvulsant oral suspension.
- Antifungal oral suspension.
What is structured vehicle in suspension?
A-Structured vehicle • Structured vehicles called also thickening or suspending agents. They are aqueous solutions of natural and synthetic gums. These are used to increase the viscosity of the suspension.
What is mixture in pharma?
DEFINITION A mixture is a liquid preparation meant for oral administration in which medicament or medicaments are dissolved , suspended or dispersed in a suitable vehicle.
What is positive mixture?
Positive mixtures – Positive mixtures are formed from materials such as gases or miscible liquids which mix spontaneously and irreversibly by diffusion, and tend to approach a perfect mix. • Negative mixtures- With negative mixtures the components will tend to separate out.
What is the meaning of diffusible dye?

Is water insoluble or diffusible?
Though insoluble in water, it is extremely diffusible through it, and is very slowly deposited. Conversely, any highly diffusible substance may be withdrawn 78 from the tissues by the blood at a similarly increased pace. In some instances a diffusible carrier is combined with the basic substances; in others not.
What is the capable of diffusing or undergoing diffusion?
Capable of diffusing or of undergoing diffusion: diffusible dyes.
What are some examples of indiffusible substances?
Examples of indiffusible substances include Aspirin, Chalk, Phenobarbitone, Succinylsulphathiazole, Sulphadimidine (for oral use); and Calamine, Zinc oxide, Precipitated sulphur, Hydrocortisone, Triamcinolone acetonide (for external use). Solid powders are finely divided by triturating in pestle and mortar with thickening agent.
