  • Patent number: 6752148
    Abstract: An inhaler disc cartridge comprises a carrier disc with radially outwardly extending resilient fingers, each with a medicament powder dosage. A sealing disc and an indexing ring are bonded to the disc. A cam sequentially and manually deflects a selected finger causing it to snap against an anvil to release the dosage by momentum energy transfer. In other embodiments, a cassette includes a carrier substrate reel of deposited powder dosages with a dosage sealing tape. The substrate comprises a belt with a plurality of transversely extending triangular fingers, each finger tip with a dosage thereon. Each finger is snapped in sequence against an anvil while a clamp secures the belt as the fingers are deflected. The spring fingers are corrugated in one embodiment cooperating with an anvil having channels and a device for inducing agglomeration breakup air streams through the channels.

  • Publication number: 20040115276
    Abstract: A liquid pharmaceutical for oral delivery wherein at the time of use, a solid unit dosage form is added to the liquid wherein the unit dosage form is comprised of a substrate soluble in the liquid and a particulate pharmaceutically active material in a pharmaceutically effective amount. At the time of use, the unit dosage form is added to the liquid, without requiring measurement of the liquid, and the entire liquid is consumed to provide for oral delivery of the pharmaceutically effective amount of material.

  • Publication number: 20020077364
    Abstract: A method is disclosed for formulating a solid dosage of thyroid hormone, while avoiding instability caused by interaction of the active ingredient with excipients. The thyroid hormone may be levothyroxine sodium or triiodothyronine. The method comprises depositing the active ingredient, preferably electrostatically, as a dry powder substantially free of excipients, onto a pharmaceutically acceptable polymer substrate. Solid pharmaceutical dosage forms also are disclosed.

  • Patent number: 6397840
    Abstract: A dry powder, for example, a medicament for an inhaler, comprises elongated particles with an aspect ratio sufficient to cause the particles to be bound to a preferably metal or non-metallic sheet material substrate at the particle tips by electrostatic deposition and for aligning a plurality of particles with their major axes aligned normal to the, substrate and oriented tip-to-tip. Particles deposited form a low density, high relative void deposition to minimize attractive forces between the particles. This minimizes agglomeration and bonding forces to the substrate facilitating the release of a powdered medicament in an inhaler. Medicament dosages in a substrate pocket are covered by a sealing layer. An embodiment of a drug dosage inhaler substrate and inhaler is disclosed.

  • Publication number: 20010033863
    Abstract: A substrate is robotically picked up at a station and transported to a measuring station to measure the distance to a reference. The substrate is aligned to a robot before measurement. The measured substrate is then transported to a pharmaceutical or diagnostic powder/grain deposition station where the powder/grains are controllably deposited on the substrate to predetermined thicknesses over a plurality of powder/grain collection zones. The deposited powder/grains are then measured to determine the thickness and area covered by the deposited powder/grains at each collection zone. The substrate is then transported to a lamination station and each collection zone of powder/grains is welded to a cover substrate. The system remembers which collection zones are out of specification so that they can be later selectively discarded.
