The inhaler has a flat inhaler body consisting of two planar parts (1, 2) of the body connected to each other along the plane (E) of the connection, in which a chamber (11) for the drug with a cavity (11') for receiving powder, an inlet (14) for air and an air channel bounded by a wall (7) and passing from the inlet (14) for air through the chamber (11) for the drug to the outlet (12) are made. The air channel is designed to provide a change in the direction of the air flow passing through the air inlet (14) relative to the outlet (12). The air inlet (14) is not located on the side of the inhaler facing away from the outlet (12). The nasal nozzle (4), made with the possibility of being placed in one nostril or in both nostrils, is made in an integral manner on the outlet (12). The outlet part (13) of the air channel between the chamber (11) for the drug and the outlet (12) has more than one bend (6), provided that there is no deagglomerating structure.
