Abstract

An inhaler in use for inhaling pharmaceutical powdered preparations through the mouth and making the same reach a trachea, bronchi and pulmonary cells. The inhaler has a generally bent form with a predetermined bend angle, preferably, at 60 degrees. The inhaler includes a hollow body, a capsule holding portion for receiving and holding a capsule, and an inhaling section. The capsule holding portion is rotated relative to a hollow body, whereby the capsule is divided into two including a barrel and a head, so that the powdered preparations can fall into the hollow body. The powdered preparations, which have fallen into the hollow body can be inhaled into a human body together with intake air flowing through air intake openings provided in the capsule holding portion by mouth suction applied to the inhaling section. The capsule barrel which has fallen into the hollow body is prevented from being inhaled into the human body due to the presence of a porous member.
