Enteric film coating composition containing enteric polymer micronized with detackifier

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.

Dependencies are inferred from the claim text.
