1. An inhaler for dispensing medicament, the inhaler comprising:
- a gas container for containing compressed gas, the compressed gas being releasable from the gas container to aerosolise said medicament; and
control means comprising a valve for controlling the passage of fresh air from the outside atmosphere to the user via a conduit;
said control means being configured to control a time interval between the aerosolisation of the medicament and the opening of the valve to allow the user'"'"'s inhalation of fresh air from the outside atmosphere in response to a change in the volume and/or pressure of the gas in the gas container;
wherein the inhaler is operable, in use, to aerosolise the medicament using the compressed gas, and harness the user'"'"'s inhalation of fresh air from the outside atmosphere to deliver the aerosolised medicament to the user by opening the valve after the time interval controlled by the control means; and
wherein said compressed gas in said gas container can be released by means comprising;
a valve used to control an air channel, anda trigger, which can be actuated manually and/or by the user'"'"'s suction force.
