    摘要: A dry powder inhaler includes a chamber holding an actuator to which a powdered medicament is adhered. Air is drawn into the chamber through an inlet flow channel and exits through an outlet flow channel. The actuator oscillates in response to the air flow, dislodging powdered medicament to be entrained in the air flow and delivered to the patient. A retaining member prevents the actuator from exiting the chamber. Thus, the medicament may be delivered to the patient without the use of carrier particles.

    摘要: Swellable particles for delivery of a drug or other working agent to the pulmonary system are provided. The swellable particles include a dehydrated (dry) aerodynamic particle diameter of 5 μm or less to enable delivery to the respiratory tract, such as for example to the tracheo-bronchial airways of the upper respiratory tract and/or to the alveolic regions of the deep lung, and a hydrated particle diameter that is greater than 6 μm volume mean diameter to retard or prevent their phagocytosis by the macrophages present in airways of the respiratory tract.
