What are gels in pharmacy?

Pharmaceutical gel is a semisolid network system, which consists of dispersion made up of large organic molecules or small particles enclosing and interpenetrated with solvent. Various advantages of pharmaceutical gels include formulation of gastro-retentive vehicle (Park et al.

What are the uses of gels?

Gels are important in everyday life, they impart the stability and application properties to many common items including cosmetics, liquid detergents, coatings, numerous food products and many household products to name but a few. They are also important in areas ranging from drug delivery to oil recovery.

What is the difference between gel and hydrogel?

Gels are materials composed of a three-dimensional crosslinked polymer or colloidal network immersed in a fluid. They are usually soft and weak, but can be made hard and tough. Hydrogels are gels that have water as their main constituent.

What is gel explain the classification of gel?

Gels are classified into elastic and non elastic gels. Elastic gels: These are those gels which posses the property of elasticity i.e. they change to solid mass on dehydration which can again be converted into gel by addition of water followed by heating and cooling.

What is the example of gel?

Gel: These are the type of colloidal solution in which the dispersed phase is in its liquid state whereas the dispersed medium is in its solid state. Some of the examples of gels are curd, cheese, butter, etc.

Are gels solid or liquid?

A gel is a liquid that is rendered solid by a more or less rigid but disordered network of microscopic particles dispersed throughout its volume. These jellylike materials are extremely common and are used in everything from foods and pharmaceuticals to paints and cosmetics.

What is gel and it types?

A gel is a colloidal system in which the dispersed phase is liquid and the dispersion medium is solid. e.g. when warm sol of gelatin is cooled, it sets to a semi-solid mass which is a gel. Jellies, jams, curd, butter, shoe polish, etc.

What kind of solution is gel?

Colloidal solution
Colloidal solution of a liquid dispersed in solid is called gel.

What are gels explain it?

Gels are colloids (aggregates of fine particles, as described above, dispersed in a continuous medium) in which the liquid medium has become viscous enough to behave more or less as a solid. Contraction of a gel, causing separation of liquid from it, is called syneresis.

What is the definition of a gel?

Definition of gel

(Entry 1 of 2) 1 : a colloid in a more solid form than a sol broadly : jelly sense 2. 2 : a thin colored transparent sheet used over a stage light to color it. 3 : a gelatinous preparation: such as.

What are gels in sport?

Sports gels are a popular choice amongst triathletes, cyclists and runners. They are a sweet, gooey, convenient source of concentrated carbohydrate, usually in a single serve pack. Most gels provide between 20-30g of carbohydrate, and usually contain sodium with no fat or protein.

What is medical gel?

Medical gels, e.g., ultrasound gels, lubricating gels, commonly used for physical examinations and diagnostic procedures, are available in either sterile or non-sterile formulations/packaging. Some types of medical gels are available in both formulations, e.g., bacteriostatic gels can be either sterile or non-sterile.

What kind of solution is gel?

Colloidal solution
Colloidal solution of a liquid dispersed in solid is called gel.

What is isotonic gel?

The GO Isotonic Energy Gel was the world’s first isotonic gel effectively delivering an easily digestible and quick supply of carbohydrate for energy during exercise. They are designed to be consumed without water, minimising the risk of being bloated that can sometimes occur with over-drinking.

Who uses energy gels?

Q: Why use energy gels? A: Runners, swimmers, cyclists or anyone who exercises for more than 60 minutes needs to adequately fuel their body for the best workout. This is important because while you exercise, your body draws on carbohydrates stored in your muscles. However, the available amount is limited.

Why do runners eat gel?

A marathon runner’s staple, energy gels replenish your depleted carbohydrate stores when running. When you run your body uses two sources of fuel to feed your muscles, fat and carbohydrates. While fat is widely available it’s slower to break down into usable energy making it ineffective when running a marathon.

Are all energy gels the same?

Energy gels are usually based on a fast release carbohydrate to provide a source of energy that your body can take in easily and use, but not all gels are the same! The source of carbohydrate, the amount and the tonicity of the gel can all vary greatly.

Are energy gels safe?

If you have no problem digesting and metabolizing sugars then energy gels are safe to use. Energy gels are designed to assist the long distance runner with energy fuel. Gels are generally considered safe when used during a long race (over 60 minutes) or workout.
