Abstract:

The present invention is directed to film coating systems for use on oral dosage forms such as compressed tablets and orally-ingestible substrates which have improved pearlescent qualities. The film coating systems can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the pearlescent film coating is prepared as a dry powder mixture containing a cellulosic polymer, a detackifier, a gloss enhancer, and a pearlescent pigment. Film coating compositions containing an aqueous suspension of the powder mixtures, methods of applying the coatings to substrates and the coated substrates are also disclosed.

Abstract:

The present invention is directed to film coating compositions for use on oral dosage forms such as compressed tablets and other orally-ingestible substrates which contain a fine particle size detackifier. The film coating compositions can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the polymer is either polyvinyl alcohol or a copolymer of polyvinyl alcohol. Aqueous suspensions comprising the inventive film coating compositions, methods of applying the coatings to substrates and the coated substrates themselves are also disclosed.

Abstract:

The present invention is directed to immediate release film coating systems for use on oral dosage forms such as compressed tablets and other orally-ingestible substrates which have improved moisture barrier properties. The film coating systems can be applied either directly to a substrate or after the substrate has been coated with a subcoat. In preferred aspects, the moisture barrier film coating is prepared as a dry powder mixture containing polyvinyl alcohol, a polymer with pH dependent solubility, a plasticizer, a glidant, and, optionally, a detackifier, an alkalizing agent and a pigment. Film coating compositions containing an aqueous suspension of the powder mixtures, methods of applying the coatings to substrates and the coated substrates are also disclosed.

International Classification:

A61K 9/24

US Classification:

424472000

Abstract:

Dry, enteric, film-coating compositions and aqueous dispersions containing the same are disclosed. When applied to orally-ingestible substrates such as oral solid dosage forms, the film coatings are capable of preventing the substrates from disintegrating in media with pH values from about 1 to about 4.5 or higher values. One preferred film-coating composition contains a micronized intermediate comprised of an acrylic resin and talc. Advantageously and surprisingly, the preferred film-coating composition does not contain an alkalizing agent.

International Classification:

G06K 19/00

US Classification:

235487000

Abstract:

Oral solid dosage forms such as tablets having overt, printed or etched markings as well as optional covert markings are disclosed. The markings can be rapidly identified to authenticate a dosage form and/or drug contained therein. The inventive dosage forms include a core portion having sufficiently low friability to receive a printed or etched marking on a surface thereof, and a readable or detectable printed or etched marking on the surface of the core which provides information allowing the identification/authentication of the oral dosage form. In preferred aspects of this embodiment, a bar code, more preferably, a 2D data matrix bar code is printed or etched on a debossed region on the surface of the solid dose form. Methods of preparing the marked dosage forms and methods of identifying and/or authenticating solid dosage forms are also disclosed.
