A multi-dose inhaler (1; 2) for medicaments in powder form comprises a container unit (24; 124) for the medicament in powder form, a withdrawal and dose preparation unit (22, 26; 122, 126) for the medicament, and a unit (16, 50; 152, 176) for mixing the dose of medicament with an air stream. The withdrawal and dose preparation unit comprises: a cup-type conveyor device (22; 122) provided with at least one cup (20; 120) for withdrawing from the container unit a certain quantity of powder and conveying it into a dispensing position, the cup (20; 120) having two coaxial identical holes (56; 156); and a plunger-type dispensing device (36; 106) disposed above the mixing unit, the plunger (36; 106) being insertable as an exact fit into and withdrawable from the holes (56; 156) in the cup (20; 120) when the latter is in the dispensing position, to cause a dose of medicament in powder form to fall into the mixing unit.
