Abstract: An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises the following components. An inhaler body for receiving a canister having a dispensing valve. A drive mechanism comprising a biasing means such as a spring and a moving component such as a yoke, the drive mechanism for driving the canister, when received in the inhaler body, from a rest position in which the valve is closed to at least an actuating position in which the valve is open. The drive mechanism drives the canister when the biasing means is released from a loaded configuration to move the moving component from a first position to a second position. A resetting mechanism, for example a mouthpiece cap arrangement for pushing upwardly on the yoke, for resetting the drive mechanism by moving the moving component from the second position to the first position and reloading the biasing means to the loaded configuration.
