Drug Dose Cartridge for an Inhaler Device

Abstract Disclosed is a dose cartridge for an inhaler device which comprises a flat pallet of airflow permeable material including a heat-vaporizing drug substance, the pallet having two opposing faces and being positioned in the dose cartridge so as to expose the two faces to airflow; a supporting member coupled to the pallet to support the pallet from at least one side of the pallet joining the two faces; and an electrically resistive heating element extending at least partially across at least one of the two opposing faces from an attachment with the supporting member. In some embodiments the resistive heating element is in thermal contact with and extends across at least two opposite surfaces of the pallet and comprises a U-shape with two ends around a hollow in which the pallet is positioned. In some embodiments a portion of the resistive heating element extending across the pallet comprises a barrier which prevents a granulate portion of the airflow permeable material from leaving the inhaler dose cartridge; and the supporting member comprises a geometry shaped for attachment to a transport arm of a dose puller.
