Zusammenfassung: | An actuator for an inhaler for delivering drug by inhalation, comprising: a housing for receiving a canister which comprises a body which includes a base and a head and defines a chamber for containing drug, and a valve stem which extends from the body and from which drug is in use delivered on actuation of the canister; and an outlet through which a user in use inhales, wherein the outlet has a substantially closed rear section which partitions the outlet from the housing, such that, on inhalation through the outlet, an air flow is drawn substantially only from an outer peripheral surface of the outlet. |
