Abstract
The present invention provides an inhaler, which separates the drug aerosolization process and the drug delivery process within the inhaler, and controls the inhalation air flow profile in a way, such that transportation of the drug in the inhaler flow channel is enveloped in a laminar air stream presented to the air tract of the user, thereby eliminating drug deposition on the inhaler inside walls. The inhaler invention therefore provides advantages over other inhalers, especially, when a repeatable emitted dose is important and generally, where contamination and hygiene in the flow channel is an issue as is the case with multi-dose inhalers.
