Abstract

An inhaler for delivering a preferably powdered formulation from a blister strip having a plurality of blister pouches. In order to achieve a compact simple construction for the inhaler and an easy action for the blister strip, the carrier extends over a circumferential angle of the inhaler of less than 360°. In particular, the carrier is guided between two deflectors with an at least substantially constant curvature, and preferably, exclusively along an outer wall of the inhaler. A conveying device of the inhaler has four drive wheels of the same diameter which are arranged on a common radius and are driven by common drive means in the same direction of rotation.
