A pharmaceutical suspension is a coarse dispersion of insoluble solid particles in a liquid medium. In addition, when compared to solution dosage forms, relatively higher concentration of drugs can be incorporated into suspension products.
What suspension means?
A suspension is a heterogeneous mixture of a finely distributed solid in a liquid. The solid is not dissolved in the liquid, as is the case with a mixture of salt and water.
Why are suspensions used in medicine?
Substances can be chemically unstable, insoluble in water, distasteful etc. Suspensions are often used as a dosage form when the drug is insoluble in water and when use of solubilizing agents is not possible.
What is syrup in pharmacy?
A syrup is a concentrated or nearly saturated solution of sucrose in water. A simple syrup contains only sucrose and purified water (e.g. Syrup USP). Syrups containing pleasantly flavored substances are known as flavoring syrups (e.g. Cherry Syrup, Acacia Syrup, etc.).
How do you create a suspension?
A suspension happens when a note from a chord is held over (or repeated) in the following chord, creating a brief dissonance with the bass. The held note then falls to a note belonging to the second chord.
What is suspension used for?
Some of them are: Paint (Use of suspension) Mud or muddy water, is where soil, clay, or silt particles are suspended in water. Flour suspended in water. Dust particles suspended in air.
Is syrup and suspension same?
Oral Syrup and Suspension both are liquid oral dosage forums but both have difference in their nature and properties.
What are ingredients used in suspension?
The possible types of excipients commonly used in the formulation of pharmaceutical suspensions include:
- 1 1. Solvents/ Vehicle.
- 2 2. Co-solvent.
- 3 3. Buffering agents.
- 4 4. Preservatives.
- 5 5. Antioxidants.
- 6 6. Wetting agents/ surfactants.
- 7 7. Anti-foaming agents.
What is the difference between suspension and oral suspension?
Oral suspensions are very similar to solutions but the drug particles do not completely dissolve into the solvent. They are, instead, “suspended” in the medium of liquid (1) very much like dust particles suspend in the air. Another commonly seen suspension is Paracetamol.
What is the best type of suspension?
Multi-link and dual wishbone systems are the holy grail of suspension designs, allowing engineers to achieve agile handling without compromising ride quality.
What are 3 types of suspension?
There are three basic types of suspension components: linkages, springs, and shock absorbers.
What makes a suspension bridge strong?
Introduction of Bridge Engineering The main forces in a suspension bridge are tension in the cables and compression in the towers. The deck, which is usually a truss or a box girder, is connected to the suspension cables by vertical suspender cables or rods, called hangers, which are also in tension.
What is a suspension example?
Ans: Common examples of suspension include the mixture of chalk and water, muddy water, the mixture of flour and water, a mixture of dust particles and air, fog, milk of magnesia, etc. In it, particles of the solute do not dissolve in the solution and are rather suspended.
What’s the difference between solution and suspension?
Difference Between a Solution and a Suspension In a solution, the solute particles that are in the solvent are evenly mixed and so small that you can’t see them. In a suspension, the pieces of solute are large and can be seen floating throughout the solvent.
What are the disadvantages of suspension?
v) Drug in suspension exhibits a higher rate of bioavailability compared to the same drug of equivalent dose formulated in tablets or capsules. This is due to larger surface area and high dissolution, e.g., antacid suspension. 1. Sedimentation of solids occasionally gives poor form of product.
How do you use suspension drugs?
Measure the liquid medication with the provided dose-measuring spoon/dropper/syringe to make sure you have the correct dose. Do not use a household spoon. For rapidly-dissolving tablets, chew or allow to dissolve on the tongue, then swallow with or without water. For chewable tablets, chew thoroughly before swallowing.
What is a suspension drug?
A suspension is a liquid with small pieces of drug. The drug is not complete dissolved in the solution. Whenever you take a suspension, you should always shake (or stir) it so that you receive the right amount of drug every time you take it.
What is the advantage of independent suspension?
Independent suspension typically offers better ride quality and handling characteristics, due to lower unsprung weight and the ability of each wheel to address the road undisturbed by activities of the other wheel on the vehicle.
What are 5 examples of suspension?
Examples of Suspension
- Muddy water.
- Milk of magnesia.
- Sand particles suspended in water.
- Flour in water.
- Slaked lime for whitewashing.
- Paints in which dyes are suspended in turpentine oil.
What are the 4 types of suspension?
Car Suspension 101: Understanding the Four Types of Spring Systems
- Leaf Springs. Leaf springs are made up of a cascading set of blades held together by a U-bolt.
- Coil Springs. If you know what a Slinky is, then you know what a coil spring looks like.
- Torsion Bars.
- Air Springs.
Can you give other examples of common suspension?
Common examples of suspensions include: Mud or muddy water: where soil, clay, or silt particles are suspended in water. Flour suspended in water. Kimchi suspended on vinegar.
What is suspension formulation?
Pharmaceutical suspensions are liquid dosage forms containing finely divided insoluble materials (the suspensoid) distributed somewhat uniformly throughout the suspending medium (suspending vehicle) in which the drug exhibits a minimum degree of solubility.
What are the strengths of a suspension bridge?
Pros of a Suspension Bridge
- It can span over long distances. Suspension bridges can span anywhere between 2,000 to 13,000 feet, which is farther than any type of bridge can accommodate.
- It is inexpensive to build.
- It is easy to maintain.
- It is incredibly versatile.
- It is aesthetically pleasing.
What are signs of suspension problems?
Suspension Warning Signs
- Continued bouncing after hitting bumps or a dipping when braking.
- A drifting or pulling to one side when turning corners.
- One side of the parked car sitting lower than the other side.
- Difficult steering.
- Unusually bumpy rides.
What is the three uses of suspension?
Flour suspended in water. Fog water suspended in air. Chalk powder suspended in water. Dust particles suspended in air.
How many types of suspension are there in pharmacy?
Based on the route of administration, suspensions can be classified as oral, topical, ophthalmic, otic, or nasal suspensions. Each of these present unique challenges and requirements in terms of desired quality attributes. These are briefly described as follows: 1.
