Abstract
A breath actuated inhalator having a primary and a secondary air flow conduit wherein regulator means are provided in the secondary air flow conduit to planate maximum air flow velocity through the inhaler. By optimizing air flow and velocity rate, the breath actuated inhalator prevents problems associated with excessive inhalation velocity such as dry powder drug compound impingement upon the outside radius of the throat.
