The present disclosure provides an inhaler having a vibration element for aerosolizing medicament contained in a blister pack, wherein individual blister packs are positioned within the housing to be simultaneously engaged with the flow channel and the vibration element. The flow channel includes a blister pack clamping surface that engages the blister pack near the top of the crown and allows the blister three rotational degrees of freedom.
