Why is film coating preferred over sugar coating?
Advantages of film coating over sugar coating
Enhances the elegance and glossy appearance of coated tablets. 3. Minimal weight increase (typically 2–3% of tablet core weight) as opposed to more than 50% with sugarcoating. 4.
What is the difference between film coated and enteric coated?
Enteric-coating polymers are pH-sensitive polymers, they are insoluble at acidic pH (stomach) but soluble at basic pH (small intestine); enteric-coating prevent tablet core disintegration in the stomach. The function of the solvent in film-coating formula is to convey coating materials to the tablet surface or pellets.
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 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 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 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 does sugar coated tablets mean?
A sugar-coated tablet is coated with sugar to disguise the taste. COLLOCATIONS: ~ tablet. A sugar-coated tablet may taste sweeter than a film-coated tablet. The hard coating on a sugar-coated tablet is similar to the sweet coatings on some candies. A sugar-coated tablet is coated with sugar to disguise the taste.
Why are ibuprofen tablets sugar coated?
About 0.04% of drug was released in the acidic phase and 99.05% in the basic medium. These results reflect that ibuprofen can be successfully enteric coated in order to prevent its release in the stomach and facilitate rapid release of the drug in the duodenum, due to the presence of superdisintegrant.
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 function of film coating?
Definition of “Functional Film Coating”:
A functional film coating has an influence on the drug release and is used to modify the release of API and achieve the desired tablet performance (as well as for other solid dosage forms like capsules, granules or pellets).
Where do film coated tablets dissolve?
Enteric coated tablets have a coating that is designed not to dissolve in the acidic environment of the stomach but to pass through the stomach into the small intestine prior to the beginning of dissolution.

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.
Which polymer is used for 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 are the different types of tablet 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.
Are coated tablets better?
Coated Tablets
*What they do: The smooth coating helps tablets go down easier and can also delay absorption. For instance, said Dr. Giardina, enteric-coated aspirin dissolves in the small intestine rather than the stomach, where it could cause irritation.
What are disadvantages of coating?
The Disadvantages of Coatings
Once a coating has been applied, it immediately begins a degradation process that will require touch-ups, maintenance, or even a complete reapplication. Coatings can also inhibit pump performance by causing obstacles or closing off passes and ports.
What kind of coating is needed for a waterproof tablet?
Sealing is done to ensure that a thin layer of water proof material, such as, cellulose or shellac acid phthalate is deposited on the surface of the tablets. The shellac or cellulose acid phthalate is dissolved in alcohol or acetone & several coats of this are given in coating pan.
Are all ibuprofen sugar coated?
Ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), is available in many different tablet formulations throughout the world. Many of these are coated, either with film coating or sugar coating.
Can film-coated tablets be broken?
Sugar or film coating – surrounds the tablet normally to make it taste better or easier to swallow. Crushing these types of tablets may make them to taste very unpleasant. Enteric coating – tablets with an enteric coating should never be crushed.
