ABSTRACT:
The invention relates to a powder inhaler (1) with mouthpiece (2) for dispersing pharmaceutical medicament formulations, which comprises an auxiliary energy source in the form of a pressure medium system (3), having a device for supplying (6) a powder formulation (7), while on activation of the pressure medium system a gaseous pressure medium (8) released by the pressure medium system (3) forms an aerosol (9) with the powder formulation (7) such that the powder particles are present in the gaseous pressure medium (8) in dispersed form. This is achieved by means of a powder inhaler (1) comprising a multi-channel nozzle, the channels of which are inclined to one another at an angle such that the aerosol jets flowing through them meet one another downstream behind the nozzle (10).
