Why are tablets coated with film?
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.
Are film-coated tablets immediate release?
