FROM POWDER TO AEROSOL Despite their apparent simplicity, dry powder inhalers are sophisticated devices. In order to deliver active drug to the respiratory tract, the user must inhale through the device. This inhalation provides energy which breaks up the compacted drug powder, a process called deagglomeration, and transports this deagglom

this article. The dispersion of a dry powder aerosol is conducted from a static powder bed. To generate the aerosol, the particles have to be moved. Movement can be brought about by several mechanisms. Passive inhalers employ the patient s inspiratory flow. When the patient activates the DPI and inhales, airflow through the device

sion outlines the design of dry powder inhaler (DPI) formulations to achieve the delivery goals. Formulation development and characterization strategies and processing methods will be discussed, with emphasis on their effect on stability, manufacturing feasibility, delivery, and bioavailability. To that end, an understanding of dry powder
Dry Powder Inhaler. Dry powder inhalers (DPIs) are dry freeflowing powdered formulations of the drug, which can be prepared by either spraydrying or micronization of a blend consisting of the drug and a suitable inert carrier.

An inhalation device for the uptake of medicaments that are in the form of dry powder contained in the blisters of specially designed single dose blister strips. The device is comprised of a mouthpiece (A), a strip support surface area (B), and one or more storage areas (C). Furthermore, the single dose blister strip is described. It is comprised of two sheets (17, 20) that are fixed in such a
