Abstract
An inhaler for multiple dosed administration of a pharmacological dry powder has a housing with a mouthpiece fitted thereon and a removable protective cap that covers the mouthpiece prior to removal. The mouthpiece may be fitted with or without lip grooves, which aid a user in the positioning and manipulation of the inhaler. The inhaler includes a dosing slide, a carriage, a dosing cavity and a valve shield, all of which are arranged within the housing. Removal of the protective cap initiates dosing, which consists of a dose of a pharmacological dry powder being received in the dosing cavity and then transported to the mouthpiece by means of the dosing slide. Only upon application of a defined minimum intensity of inhalation is the shutter moved by the suctioned valve shield, resulting in the release of the dose for inhalation.
