Some tablets have a special coating that prevents them from breaking down in the stomach. This coating helps ensure that the tablet will only dissolve after entering the small intestine. Other tablets come in chewable forms, or as orally dissolving tablets (ODT), which break down on their own in saliva.

What are capsules coated with?

Materials used for enteric coatings include fatty acids, waxes, shellac, plastics, and plant fibers. Conventional materials used are solutions of film resins.

Why are tablets film coated?

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.
