摘要:A therapeutic preparation consisting of particles containing a therapeuticallyactive material are coated with a disintegratable coating comprising zein and shellac. Afirst group of particles contains no coating or a coating subject to rapid disintegrationupon ingestion to release an initial dose of therapeutic material and remaining groups ofparticles are coated with increasingly thicker coatings for delayed disintegration torelease subsequent doses of therapeutic material. The coating composition may includedisintegration modifiers so that thinner coatings of the zein-shellac coating material canbe employed than would be required for zein shellac alone to obtain the delayeddisintegration of the coating.
