A medicament dispensing device, a medicament magazine thereof, and a method of removing a medicament from the medicament magazine. The inhaler has a mouthpiece () and an air channel () connected thereto, as well as a medicament magazine with at least one medicament chamber containing a powdered medicament. A drive current is produced in the air channel, while a vacuum flow (') can be produced by the drive current and a constriction formed in the air channel. This narrowest part of the air channel that produces the vacuum flow is connected to a removal opening () which communicates with a control opening (), in order to form an emptying current through the control opening via the removal opening. In a preferred embodiment the at least one medicament chamber including the control opening, the removal opening and a fill opening are housing in the one-piece medicament magazine.
