Beschreibung
Zusammenfassung:	Various embodiments of a device for delivery of a medicament and a method of utilizing such device are disclosed. The device can include a canister and an actuator. The actuator includes a housing receiving the canister; a valve block receiving a metering valve of the canister, the valve block defining an expansion chamber for passage of propellant and medicament expelled from the canister; and a nosepiece for insertion into a user's nostril, the nosepiece including a fluid passage and a delivery opening for expulsion of the propellant and medicament into the user's nostril. A flow path is defined through the actuator for passage of propellant and medicament from the canister and includes the expansion chamber, the fluid passage and the delivery opening. Further, the cross-sectional area of the flow path is greater than the lowest cross-sectional area of the metering valve at all points along the flow path.
