Abstract
An inhalation-activated inhalator having a flow diverting means wherein the primary air flow channel is blocked for a brief period during inspiration with air flow during that period passing through a dosing chamber arrangement and connecting passage to inject medicament into the inspired air stream is provided. By diverting the inspired air stream in this fashion, powdered medicament may be provided for inhalation at a particular point in the patient's inspiration cycle, thereby optimizing the delivery of medicament to the lungs.
