Abstract

A multidose powder inhaler for dispensing powdered medicament by inhalation comprises a medicament container, an air channel, a metering member, and a loose agitation element, particularly in the form of a sphere, disposed inside the medicament container. The agitation element, which can be made of a conductive material, improves the dosing accuracy, when the device is shaken.
