An apparatus (1) for the nasal or oral delivery of a medicament, comprises: (a) a sealed flexible container (3) containing the medicament and a gaseous propellant for the medicament; and (b) a delivery device (5), comprising: (i) a main body part (5a) which, at least in use, holds the sealed flexible container (3); and (ii) a compressive part (5b) which, when actuated in use, causes the sealed flexible container (3) to be ruptured and the propellant to expel the medicament from the container, thereby delivering the medicament.
