Dry powder inhalation system Dry powder inhaler systems for pulmonary release of pharmaceutical products are described. dry powder inhalation systems comprise a dry powder inhaler or inhaler (109) and a cartridge (1600) containing a pharmaceutical formulation comprising an active ingredient for release to the pulmonary circulation. The present devices provide resilient devices that are reusable, use pre-metered single dose cartridges that release a drug in a linear manner, and can be disassembled for cleaning. The devices also provide a high strength inhalation system that enables dry powder particle de-agglomeration, has a consistent air flow, is easy to manufacture and is simple and relatively easy to use. |
