  • Publication number: 20030164380
    Abstract: The present invention relates to a package system intended to simplify the usage of multiple medications stored separately and used together, thereby minimize the non-compliant use of the multiple medications. Generally, the separate medication components are contained in a plurality of cavities, arranged in one or more arcs or concentric circles. The package system further includes an access shield having one or more openings, which are selectively aligned in one of a plurality of positions, corresponding to the per use groupings. When the one or more openings in an access shield are aligned with the cavities corresponding to one of the per use groupings, the medication components are capable of being released from their respective cavities. Conversely, the shield substantially restricts access to the medication components located in the non-aligned cavities.
