  • Publication number: 20070196489
    Abstract: Taste masked particles and chewable tablets made therefrom are disclosed. The taste masked particles comprise a core containing an active ingredient and a polymeric coating covering said core, said coating comprising a mixture of a) an enteric polymer; and b) an insoluble film forming polymer, the surface of said particle being free of active ingredient. The chewable tablets provide immediate release of the active ingredient.

  • Publication number: 20040062804
    Abstract: A dosage form comprises: (a) at least one active ingredient; (b) a core; and(c) a shell which surrounds the core, wherein the shell is substantially free of pores having a diameter of 0.5-5.0 microns, and the shell comprises a first shell portion and a second shell portion which are compositionally different and the dosage form provides a modified release profile of the active ingredient upon contacting of the dosage form with a liquid medium.

  • Publication number: 20030232082
    Abstract: A dosage form comprises: (a) at least one active ingredient; (b) a core having an outer surface; and (c) a shell which resides upon at least a portion of the core outer surface, wherein at least a portion of the shell is semipermeable, such that the liquid medium diffuses through the semipermeable shell or shell portion to the core due to osmosis. The shell also provides for delivery of the active ingredient to a liquid medium outside the shell after contacting of the dosage form with the liquid medium. The dosage form delivers one or more active ingredients in a controlled manner upon contacting of the dosage form with a liquid medium. The dosage form may be employed to provide a burst release of the active ingredient, or to provide release of the active ingredient at an ascending release rate over an extended time period upon contacting of the dosage form with a liquid medium.

  • Publication number: 20020119196
    Abstract: Texture masked particles and chewable tablets made therefrom are disclosed. The texture masked particles are comprised of a core containing an active ingredient, an optional first coating layer comprised of a taste masking agent that substantially covers the core; and a second coating layer, which optionally may substantially cover the first coating layer or the core, comprised of a film forming polymer and a anti-grit agent. The particles may be produced into a tablet form, such as a chewable tablet form, that provides for the immediate release of the active ingredient.

  • Patent number: 6149943
    Abstract: The present invention provides a core of predominately microcrystalline cellulose, on which an active drug is layered onto the core via solution coating. The coated particles have a narrower particle size distribution than coated granules provided by other processes. An optional final coating of a pharmaceutically acceptable polymeric coating is provided to provide tastemaking or controlled release, and protection of the drug-layered particles.
