moving an actuation button of a nasal drug delivery device, the nasal drug delivery device including a housing, an outlet, a medicament container containing a powdered medicament, a compressed gas container containing a compressed gas, wherein a fluid flow communication between the medicament container and the compressed gas container is closed prior to movement of the actuation button, a first needle, and a second needle;
piercing the medicament container with the first needle in response to movement of the actuation button; and
piercing the compressed gas container with the second needle in response to actuation of the actuation button, wherein when the medicament container and the compressed gas container are pierced the fluid flow communication between the medicament container and the compressed gas container is opened for expelling the powdered medicament from the medicament container out of the outlet.
