Suspensions are often used as a dosage form when the drug is insoluble in water and when use of solubilizing agents is not possible. Based on method of preparation, suspensions can be divided into two categories, flocculated and deflocculated systems.
What are the applications of suspension?
The suspension supports the weight of the vehicle body and also protects the vehicle and any cargo from damage and wear.

There are three basic types of suspension components: linkages, springs, and shock absorbers.
What are the two types of suspension?There are two general classifications of suspension systems known to date; dependent and independent. A dependent suspension system connotes that there is a beam or axle that connects the left wheel to the right so they work in tandem with each other.

Why is suspension important?
Specifically, the suspension system maximizes the friction between the tires and the road to provide steering stability and good handling. … Worn suspension components may reduce the stability of the vehicle and reduce driver control, as well as accelerate wear on other suspension system components.
What is difference between emulsion and suspension?
An emulsion is similar to a suspension only in that it is a mixture of two components. … Unlike a suspension, which can consist of two components of any phase, an emulsion is a mixture of two liquids.
What factors affect suspension?
- Dispersed phase content. The content of the dispersed phase φ is the most important physical parameter that affects the viscosity of dispersions. …
- Particle shape. …
- Particle size and size distribution. …
- Temperature.
How are suspensions made stable?
In a suspension, particles move as a result of Brownian motion or under the influence of gravity. Kinetic stability is facilitated by slowing down such movement, inhibiting aggregation and decreasing sedimentation.
Is Aluminium hydroxide a suspending agent?
Viscous aluminum hydroxide products, such as Visco 6 and Visco 9, are typically used in regular-strength antacid suspensions. These products yield thick and creamy formulations without requiring the use of additional thickeners or suspending agents.
Which of the following belongs to pharmaceutical aid?
They include solvents, diluenting agents, suspending agents, antioxidants, preservatives, coloring agents, flavoring agents, excipents, ointments, bases.
Why We Use suspending agent in suspension?
Suspending agents are physiologically inert substances which increase viscosity when added to suspensions. … Therefore, a second important function for suspending agents is to facilitate redistribution of a suspension on shaking. Particles in suspension can come together to form either floccules or aggregates.
