The benefits of tablet/film coating
Protective film without function.
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.
Functional protective film.
The tablet core is coated with a functional coating, e.g. to achieve an odour or taste masking. Furthermore, it is possible to achieve protection against environmental influences such as oxidation, UV radiation and moisture. Other functions include the targeted or delayed release of the active ingredient, protection against stomach acid, protection of the mucous membrane and reduction of side effects.
