Pharmaceuticl suspensions are solid dipersion of insoluble or sparingly-soluble drugs, in aqueous or oily vehicles. They are intended for oral administration, topical application or parenteral administration of drugs.

Aerosol suspension of finely divided, or micronized drugs, is also another class of pharmaceutical preparations intended for inhalation.

Suspension of drugs for oral administration is an easy way to administer insoluble, or sparingly soluble, drugs to infants and eldery who have difficulty in administering drugs in tablet or capsule forms. Also for rapid absorption of some insoluble drugs, which are slowly absorbed from tablet dosage form, such as griseofulvin, prepared in suspensions form of the micronized drug.

The insoluble basic drug, or the insoluble salt or compound of a drug, is frequently used rather than using the soluble salt, to retard absorption of the drug. This is used for the preparation of prolonged released dosage forms to avoid frequent administration of the drug.

Sometimes insoluble salts or compounds of the dugs are used to avoid the bitter taste of the soluble form; for example the use of chloramphenicol palmitate in suspension, instead of using the very bitter soluble chloramphenicol.

Some eye drops or ear drops are also prepared in suspension form for drugs which are sparingly soluble, or intenetially using the insoluble form to prolong the time of action of the drug, such as corticosteroid preparations. Samir M. Bayoumi

Examples for animal cell suspension culture?

Some examples of animal cell suspension culture include the growth of Chinese hamster ovary (CHO) cells, mouse myeloma cells, and human embryonic kidney (HEK) cells in suspension in a nutrient-rich medium. These cultures are commonly used in biotechnology and pharmaceutical research for protein production and cell-based assays.


What are the uses of suspension in chemistry?

In a pharmaceutical suspension, a suspending agent helps the drug stay in the body of your suspension thereby preventing caking at the bottom. One of the properties of a well-formulated suspension is that it can be easily resuspended by the use of moderate agitation.


What contains undissolved solids?

A mixture that contains undissolved solids is known as a suspension. In a suspension, solid particles are dispersed throughout a liquid but do not dissolve, resulting in a cloudy appearance. Common examples include muddy water, where soil particles are suspended, and certain pharmaceutical preparations, like some liquid medications that contain solid ingredients. Over time, the solid particles in a suspension may settle to the bottom if left undisturbed.


What are Three properties of a good pharmaceutical suspension?

1. any sediment (solid material) which accumulates when stored is readily dispersed. 2. After gently shaking, the medicine stays in suspension long enough for a dose to be accurately measured 3. The suspension is pourable


What type of food is a suspension?
