Disclosed is an inhaler for inhaling powdered medicaments from capsules with improved operability. The inhaler comprises a lower part, and a plate that can be latched to the lower part, by means of which the lower part can be closed off. A capsule holder can be lowered into the lower part for holding capsules, and a mouthpiece that can be latched to the plate. An actuating member is set in motion from a resting position and interacts with at least one pin in a pin holder, that can be pushed into the capsule holder. The actuating member is in two parts, such that it comprises an outer actuating member providing a push-button for a user and an inner actuating member providing the pin holder, where- the outer actuating member is larger than the inner actuating member, and the outer actuating member is constructed such that the pin holder is situated above the point of application of the force and below the suspension of the push-button. A force of 10-25N have to be applied in order to perforate a capsule in the capsule holder by moving the outer actuating member.
