Pharmaceutical film coating is considered a key part in the production of solid pharmaceutical dosage forms since it gives superior organoleptic properties products. In addition, it can improve the physical and chemical stability of dosage forms, and modify the release characteristics of the drug.

What is the main purpose of a film coated tablet?
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.
Why are certain medications coated?
Medication coatings serve many purposes; they provide colour to establish brand identity, mask bitter taste, supply a hard cover for crumbly or brittle compounds so a medicine does not dissolve in the mouth, and increase product shelf life.
What is the difference between film coated and uncoated tablets?
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.
Can I break film-coated tablets?
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?
Film coating involves the deposition of a thin layer of film-forming polymeric onto a product substrate. The process can be carried out using conventional panning equipment but nowadays more sophisticated equipment is used to achieve efficient drying, high degree of automation and coating time.
Are film-coated tablets safe?
Film or sugar-coated medicines
Disruption of the film or sugar coating on a drug may result in rapid degradation of the active ingredient and may also cause skin irritation in patients or carers.
How long do film-coated tablets take to dissolve?
In general, it typically takes approximately 30 minutes for most medications to dissolve. When a medication is coated in a special coating – which may help protect the drug from stomach acids – often times it may take longer for the therapeutic to reach the bloodstream.
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.
Do film coated tablets contain sugar?
Due to the increase in tablet size caused by sugar coating, drug manufacturers have largely changed to using ‘film coatings’. These are very thin layers of a safe ingredient placed around the tablet to again protect the tongue from the flavour of the contents and protect the contents from moisture and light.
What is the 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.
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.

What is the meaning of film coated?
Definition of ‘film-coating’
Film-coating is a process in which a tablet, capsule, or pellet is covered by a thin layer of film to protect it or make it easier to swallow. Applying a thin coating to tablets is called film-coating. The outer layer applied in film-coating makes tablets easier to swallow.
What is coating in pharmaceuticals?
by Pharmapproach | May 16, 2021 in Pharmaceutical Technology. Tablet coating is a process by which an essentially dry, outer layer of coating material is applied to the surface of a dosage form in order to confer specific benefits over uncoated variety.
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.
Are film coated tablets immediate release?
Immediate Release Film Coating Systems for Tablets
Colorcon, the innovator and industry standard for one step, fully formulated film coating systems, offers a range of color-matched, custom pigmented, or clear film coatings for immediate release solid dose applications.
What is the coating on Tylenol made of?
Gluten-, lactose-, and tartrazine-free. Each solid, capsule-shaped tablet, coated with red gelatin on one end, blue gelatin on the other end, a gray band between the two gelatin-coated ends, printed “TY” on one gelatin-coated end and “500” on the other gelatin-coated end, contains 500 mg of acetaminophen.
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.
