What are the benefits of film coating?
Film coatings are widely used in pharmaceutical oral dosage forms such as tablets, pellets, granules, and drug crystals. Coatings are used for a variety of reasons including
masking tastes, improving stability, ease of swallowing, and assisting in identification
.
What is the meaning of film coating?
A film coating is
a thin polymer-based coat applied to a solid pharmaceutical dosage form such as a tablet
. The thickness of such a coating is typically between 20-100 μm. It is possible to follow the dynamic curing effect on tablet coating structure by using non-destructive analytical methodologies.
Which material is used for film coating?
A film-forming polymer, which provides the mechanical strength of the film. 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.
Are film coated tablets better?
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.
How does film coating work?
The process of film coating involves the
deposition of a thin, but uniform polymer-based formulations
onto the surface of solid dosage forms such as tablets, capsules, powders, granules, or pallets under conditions that permit: Balance between, and control of, the coating liquid delivery rate and drying process.
What are drugs coated with?
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 difference between film coating and sugar 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 process of coating?
The coating process consists of
applying a coating material to a moving web of flexible substrate
. The carrier substrate may be paper, film, or aluminum foil and the resulting material’s additional properties will vary depending on the required application and on the material’s end-use.
What is the purpose of film coated tablets?
Film coating is a common step in tablet manufacture that can be used
to improve product appearance, organoleptic properties
, or to facilitate swallowing. Functional film coats can also be used as a part of the product’s stabilisation strategy and to modify or delay drug release.
What are the different methods of coating?
- Dip Coating. Cost effective process provides uniform high quality coating on different shaped/sized substrates including large surface areas. …
- Brushing. …
- Roll Coating. …
- Spraying. …
- Spin Coating. …
- Flow Coating.
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.
Where do film coated tablets dissolve?
use on tablets
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.
Why are some pills not coated?
The lack of coating means
the pill isn’t very slippery and can start to disintegrate the moment liquid hits it
. Take uncoated pills in the same way you would swallow coated pills, but take steps to avoid residues and aftertastes, and ensure that the pill doesn’t melt on your tongue before you can swallow it.
Why are ibuprofen tablets coated?
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.
What is the difference between coated and uncoated tablets?
What are Tablet Pills. … Tablets can be either coated with a sugar or film coating, or uncoated. Uncoated tablets are rougher, may be more difficult to swallow, and often leave a bad taste in the mouth when swallowed. A coated tablet
generally goes down easier and with less aftertaste
.
