The reasons for the formulation of a pharmaceutical suspension: — when the drug is insoluble in the delivery vehicle. –To mask the bitter taste of the drug. –To increase drug stability.
What are the pharmaceutical uses of suspensions?
The suspension dosage form has long been used for insoluble and poorly soluble drugs for making oral, topical and parenteral products. Pharmaceutical Suspensions, From Formulation Development to Manufacturing provides the reader with a broad overview of suspension drug product technology.
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.
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 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 are 3 types of suspension?
There are three basic types of suspension components: linkages, springs, and shock absorbers.
What drugs are suspensions?
Examples of a few of the oral suspensions in which a specific and well defined particle size specification for the drug substance is important include phenytoin suspension, carbamazepine suspension, trimethoprim and sulfamethoxazole suspension, and hydrocortisone suspension.
What are 5 examples of 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. Chalk suspended in water. Sand suspended in water.
What are the two major types of suspension?
There are two types of springs used for suspension a coil spring and a leaf spring. A coil spring is a common one which most you might have seen. A leaf spring is used on a solid axle so basically in trucks and has very high energy storing capacity compared to a coil spring.
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 are 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.
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.
What are the classification of suspension?
Suspensions are classified on the basis of the dispersed phase and the dispersion medium, where the former is essentially solid while the latter may either be a solid, a liquid, or a gas. three types: suspension mixture, colloidal mixture or solution, according to how they combine and can be separated.
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 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.
How do you make suspension drugs?
Carefully add cool boiled water to about half the height of the final marking on the bottle. Close the cap. Shake the bottle until all the powder is thoroughly mixed. Allow the suspension to stand for about 2-5 minutes to rid the air bubbles in the bottle.
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.
Which type of suspension is best?
Multi-link and dual wishbone systems are the holy grail of suspension designs, allowing engineers to achieve agile handling without compromising ride quality.
Which of the following is the best example of 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.
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.
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.
What are the 10 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 reasons for preparing suspensions?
The reasons for the formulation of a pharmaceutical suspension: — when the drug is insoluble in the delivery vehicle. –To mask the bitter taste of the drug. –To increase drug stability.
