The invention relates to the preparation of inhalation powders comprising a delayed active ingredient release, and a method for the manufacture thereof, as well as the medicines producible using said inhalation powders.
摘要:
The invention relates to a medicament delivery device, especially a multidose powder inhaler, for delivering individual doses of a medicament. A plurality of medicament compartments (4, 5) are arranged in a medicament carrier in the form of an endless loop. The medicament compartments form groups in such a manner that a mouthpiece (2) reaches different groups by a substantially complete travel around the medicament carrier. Therefore, a plurality of medicament compartments (4, 5), typically one, two or three, can be arranged between two consecutive withdrawal positions. The invention allows provision of a very high density of medicament compartments (4, 5) and thus an inhaler device which can be very compact in design even when accommodating a large number of individual doses.
摘要:
The invention relates to a medicament carrier comprising a plurality of medicament doses, said carrier being formed from a single web of film in which pouches (2) for accommodating a medicament are defined. At least one face of the web of film has openings (4) for transport spikes to engage therewith, thereby allowing the web to be transported. The web of film, in the area of the pouches, has a defined width which is smaller than the width of the film in the remaining areas, the openings being arranged in the wider area of the web of film. The invention also relates to a method and a device for opening said medicament carrier, the device being preferably configured as a segmented wheel.
