Definition. ➢ A Pharmaceutical suspension is a coarse dispersion in which internal phase (therapeutically active ingredient)is dispersed uniformly throughout the external phase.
What is suspension in pharmaceutics 2?
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 is a drug suspension?
In a suspension, the medicine is mixed with a liquid, usually water, in which it cannot dissolve and therefore remains intact in the form of small particles. Elixirs are typically more concentrated, so remember to always read the dosage instructions on the bottle before giving your child any medication.
What are the disadvantages of pharmacy?
Cons of being a pharmacist The educational requirements are extensive. The education is expensive. You may need to stand for long periods. The work can be stressful. The environment can be hectic with great responsibility. You may need to work off-hours, weekends, and holidays.
Why are some drugs suspended?
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.
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 the difference between suspension and solution?
The difference between a solution and a suspension is in the particle sizes involved. A solution is a mixture of ions or molecules (very, very small). Solutions are transparent, meaning that you can see through them. A suspension has bigger particle sizes and so it may look cloudy or murky.
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 3 types of suspension?
There are three basic types of suspension components: linkages, springs, and shock absorbers.
Is salt water a solution or suspension?
Salt dissolved in water is a solution.
What are the disadvantages of suspension?
Suspensions also possess some disadvantages relative to other dosage forms. The primary disadvantage is their physical instability; i.e., that they tend to settle over time leading to a lack of uniformity of dose.
Is peanut butter a suspension?
Examples of a suspension include the following: Whole milk, peanut butter, some salad dressings, hot chocolate, oil paint, muddy river water.
What is syrup in pharmacy?
Syrups. Syrups are a concentrated solution of a sugar mixed in water or other other aqueous liquid. In medical terminology, medicinal syrups or syrupus are nearly saturated solutions of sugar in water in which medicinal substances or drugs are dissolved. Basically, it is an oral suspension in liquid form.
What is the difference between suspension and oral suspension?
Unlike pharmaceutical syrup, oral solution is relatively similar only that the drug particles do not dissolve into solvent completely. Finally, the solution will form two distinct layers where the top layer is less concentrated than the bottom one. For young children, most of the suspension used is liquid antibiotics.
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.
How do you make flocculated suspension?
Electrolyte and ionic surfactant can be used as flocculating agents to produce a flocculated suspension. suspension prepared without flocculating agent is a deflocculated one. The physical stability of the suspension is assist by determining the sedimentation volume or degree of flocculation.
Why are suspensions better than solutions?
Particles in a suspension tend to travel through the medium and undergo sedimentation with time. Due to the large sizes of particles, they can be easily separated by filtration. Suspensions are cloudy, unlike solutions due to bigger particle size. Light is scattered or reflected by these particles.
Is oil and water an example of a suspension?
Suspensions. Simply defined as a heterogeneous mixture of two substances in which one is dispersed into the other, suspensions involve particles larger than those found in solutions, typically over 1,000 nm. Examples of suspensions include oil and water, dust or soot in air, sand and water and muddy water.
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.
What are the advantages of suspension?
The following advantages can be obtained by formulating API as a suspension dosage form. Suspensions are a useful drug delivery system for therapeutic agents that have a low solubility. Pharmaceutical suspensions may be formulated to mask the unpleasant/ bitter taste of drug.
What are the suspending agents?
A suspending agent is a liquid in which a solid substance can be held in suspension. The drug is held in the suspension by a suspending agent, and does not settle at the bottom. If the tablet is dissolved in a suspending agent, this will help suspend any insoluble components in the liquid.
Is liquid medicine is an example of suspension?
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 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.
