What is sugar coating? The process of sugar coating, which has its origins in the confectionery industry, involves the successive deposition of aqueous sugar solution on the tablet cores as they are rotated and tumbled in a revolving pan by spraying sugar solution or suspensions into pans and drying off the solvent.

Why is sugar coating better than film coating?
Pharmaceutical tablets can be film coated in a single stage process that is rapid and results in minimal weight gain of at 2 – 3% compared with sugar coating which adds 60 to 80%. The film coat does not significantly affect the tablet’s disintegration process.
What is the purpose of sugar coating?
Sugar coating is used in immediate release applications to mask unpleasant taste and odour of some drugs or to improve aesthetic qualities of the product. It should be understood that the coating process will add some time to the overall disintegration of the tablet and may impact drug dissolution.
What is sugar coating process?
The sugar coating process involves building up layers of coating material on the tablet cores by repetitively applying a coating solution or suspension and drying off the solvent. The process consists of various steps, each designed to achieve a particular function.
What is meant by film coating?
A film coating is a thin polymer-based coat that is typically sprayed on to a solid pharmaceutical dosage form, such as a tablet, capsule, pellet or granule. Film coating can impact both its appearance and its pharmacokinetics making it an essential process in making the final drug product.
What is the disadvantage of sugar coating?
Disadvantages of Sugar Coating
It may also hide or mask the unsavoury taste of the drug that some patients may find unpalatable. Sugar coating insulates and masks the colour and texture of the tablet’s core. It may also influence the release of the encased drug in the body.
What is the difference between sugar coating and film coating?
Film coating involves the deposition, usually by spraying a liquid coating system, of a thin film of a polymer-based formulation onto the surface of a tablet, capsule or multiparticulate core. Sugar coating is a more traditional process closely resembling that used for coating confectionery products.
What is sugar coating called?

Which is first step in sugar coating?
It involves the application of large quantities of sugar-coatings to the tablet core, significantly increasing the tablet weight by 50 – 100 %. Subcoating provides the rapid buildup necessary to round up the tablet edge.
What are the coating materials?
Typical coating materials are:
Pure metals, such as Aluminum (Al), Copper (Cu), Molybdenum (Mo), etc. Alloys, such as Nickel Chrome (NiCr), Nickel Aluminum (NiAl), Aluminum Bronze (CuAl), etc. Ceramic (Oxide), such as Aluminum Oxide (Al2O3), Chrome Oxide (Cr2O3), Zirconium Oxide (ZrO2), Titanium Oxide (TiO2), etc.
Which polymer is widely used in film coating?
The most widely used polymers in non-functional film coating are cellulose derivatives such as hypromellose. Plasticizers, used to improve the flexibility of the film formed and prevent it from cracking or breaking.
What is the principle of coating process?
Coating process: – The basic principle of tablet coating is simple. Tablet coating is an application of coating composition to a moving bed of tablets with the concurrent use of heated air to facilitate evaporation of the solvent.
How many types of coating pans are there?
three types
There are three types of conventional coating pans. Besides conventional coating pan, there are perforated coating pans.
What is the benefit of film coated tablets?
In non-functional films, the tablet core is provided with a thin film coating, to e.g. isolate the drug and thus prevent its volatilization. The protective film improves the mechanical stability, the aesthetics, the identity, the storage conditions and the flow properties as well as the surface structure of the tablet.
What are the benefits of coating?
Coatings help protect against the damage caused by wear-prone applications. They have been designed to be wear resistant, reduce friction, protect against caustic/acidic materials and cleaning agents, and increase line efficiencies. Coatings come in two categories – organic and inorganic.
What are the different types of pill coating?
Types of Coating Materials for Tablets
- Sealing. Using a seal coat over the tablet prevents moisture from entering the tablet’s core.
- Sub-Coating. Sub-coating is used to round the edges of the tablet and increase its weight.
- Syrup Coating. The tablet’s imperfections are covered using syrup coating.
- Coloring.
- Polishing.
What is the red coating on ibuprofen?
Enteric coating is a polymer applied to oral medication. It serves as a barrier to prevent the gastric acids in the stomach from dissolving or degrading drugs after you swallow them. Without full enteric protection, many drugs would fall apart rapidly in stomach acids.
What is the opposite of sugar coating?
Opposite of having a pleasant taste characteristic of sugar or honey. unsweetened. nonsweet. sugarfree. sugarless.
Where does the term sugar coating come from?
The expression sugar coat came into use in the 1870s to mean to literally coat something with sugar. By the turn of the twentieth century, the term took on a figurative meaning. The closed compound word, sugarcoat, is currently more than three times as popular as the hyphenated form, sugar-coat.
