Abstract

Various exemplary drug delivery devices with a spinning nozzle, drug products utilizing the same, and methods of using drug delivery devices with a spinning nozzle are provided. In general, a nasal drug delivery device configured to dispense a drug therefrom includes a spinning nozzle configured to facilitate the drug's ejection into a patient's nose. The spinning nozzle is located between a drug holder containing the drug to be dispensed and an opening of the drug delivery device through which the drug exits the drug delivery device. The spinning nozzle is configured to spin during the drug's delivery as the drug travels from the drug holder and out of the drug delivery device. The spinning nozzle includes a plurality of perforations therein through which the drug as a liquid is configured to pass. The spinning of the spinning nozzle causes the drug to exit the drug delivery device as a fine mist.
