  • Publication number: 20030232083
    Abstract: The invention provides a dosage form comprising at least one active ingredient, and first core and second cores surrounded by and separated by a shell. The dosage form provides a delay of at least one hour between the initial release of active ingredient contained in said first core and the initial release of active ingredient contained in said second core after 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.

The composition may optionally additionally contain up to about 40 weight percent of at least one compatibility material for retaining the non-aqueous carrier material in the edible solid composition. The compatibility material is selected from the group consisting of emulsifiers, acrylic polymers, waxes and combinations thereof. The edible solid composition may be used as a core or shell in a dosage form, or as a dosage form per se which contains or is prepared from such an edible solid composition.

  • Publication number: 20030217908
    Abstract: An apparatus for continuously transferring substrates such as tablets from a rotary, double-sided tablet press to a second location is provided. The apparatus comprises a flexible conveying means on which transfer units adapted to receive the substrates are mounted. The flexible conveying means travels along a path that is coincident with those portions of the tablet press where tablets are ejected.

  • Patent number: 6516949
    Abstract: A non-through score line is made in the exposed surface of the blister sheet of a blister package. The non-through score line extends from one edge of an individual blister unit to an opposite or adjacent edge, i.e., across the corner of the blister unit. When the blister unit is angulated or flexed back at the non-through score line, the blister sheet will fracture. The smaller portion of the fractured blister sheet, still bonded to a backing sheet, acts as a tab for peeling the backing sheet from the blister sheet exposing the blister contents. Camouflage lines on the blister sheet help hide the score line, thereby rendering the package highly child-resistant.

  • Patent number: 6013306
    Abstract: A nozzle assembly is provided with a valve to enable the coating of low aspect ratio items such as tablets. In a preferred embodiment a valve is disclosed such that the vacuum forces acting on the surfaces of the valve are equal to the weight of the valve. This balancing of the weight of the valve and the vacuum forces allows gravity to be the primary motive force for actuation. The weight of the valve is used to detect a tablet, such that when a tablet is missing, the valve prevents any coating from being pulled into the nozzle.
