Abstract
A passive inhaler for delivery of a powder-form inhalation formulation from a blister strip with a plurality of blister pockets is proposed. The inhaler includes an impaction element onto which the air stream can impact together with entrained inhalation formulation for better deagglomeration. Alternatively, the inhaler includes an oscillating and/or vibrating device for better de-agglomeration of the inhalation formulation. Alternatively or additionally, the inhaler includes one or two mixing means for generating swirls, preferably with opposite rotation directions.
