    摘要: Enteric film coating systems for orally ingestible substrates such as pharmaceutical tablets and dietary supplements are disclosed. In preferred aspects, the enteric film coatings include an ethylcellulose dispersion and a substantially gastro-insoluble pore former such as sodium alginate.

    摘要: 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.
