Abstract
An inhaler device () contains, or is capable of accepting, a plurality of doses of a medicament to be dispensed from the inhaler (). To ameliorate the problem of double dosing from the inhaler (), the device further comprises prevention means () for preventing, at least temporarily, the dispensing of a dose of medicament, and detection means () for detecting the inhalation of a previously dispensed dose of medicament. When the detection means () detects the inhalation of the previously dispensed dose of medicament, it releases the prevention means (), allowing the device to dispense a further dose of medicament. The detection means () may be a pressure sensor, and the prevention means () may operate by causing a disengagement of an actuation mechanism.
