The invention relates to a system composed of an inhaler and a capsule, preferably intended for single use. The capsule contains a preferably powdered pharmaceutical preparation which, for inhalation, is expelled from the capsule through at least one hole. The capsule comprises as capsule elements a capsule cap and a capsule body, at least one of which comprises at least one prefabricated hole. The prefabricated hole in the capsule is sealed off in the transporting state of the system and is open in the usage state. The hole is exposed by actuation of a pulling mechanism. Prior to this the hole is closed off by a capsule receptacle or a film.In one embodiment the capsule may be present in two different states, for example in different insertion positions of the capsule elements. In the first state the prefabricated hole is closed off and in the second it is exposed.Also shown is an inhaler suitable as a disposable product, which is manufactured from thermoformed parts or from blister film.
