    摘要: The present disclosure provides dry powder compositions of treprostinil prodrugs and methods of treating pulmonary hypertension (e.g., pulmonary arterial hypertension or PH associated with interstitial lung disease), in a patient in need thereof with the same. The dry powder composition includes (a) from about 0.5 wt % to about 5 wt % of a compound of Formula (I):




    a stereoisomer thereof, or a pharmaceutically acceptable salt thereof, (b) from about 10 wt % to about 61 wt % of leucine, and the balance being (c) a sugar selected from the group consisting of trehalose and mannitol. The entirety of (a), (b), and (c) is 100 wt %, and R1 is tetradecyl, pentadecyl, hexadecyl, heptadecyl, or octadecyl. The method of treating PH includes administering an effective amount of the dry powder composition to the lungs of the patient by inhalation via a dry powder inhaler, during an administration period. In certain compositions and methods provided herein, R1 is hexadecyl, e.g., linear hexadecyl.

    摘要: 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.
