ABSTRACT:
An inhaler apparatus having a housing having first and second walls and defining an air inlet and an air outlet. The first and second walls define an internal housing volume and have portions being movable relative to each other so as to expand the internal housing volume from a non-inhalation state, wherein the internal housing volume has a first volume, to an inhalation state, wherein the internal housing volume has a second volume. The second volume is larger than the first volume. An air flow chamber is defined within the housing between the air inlet and the air outlet when the housing is in the inhalation state. A medicament is contained between the first and second walls. The medicament is exposed within the air flow chamber when the housing is in the inhalation state.
