METHOD OF DEPOSITING A DRY POWDER AND DISPENSING DEVICE |
摘要 |
<p>A dry powder, for example, a medicament for an inhaler, comprises elongated particles with an aspect ratio sufficient to cause the particles to be bound to a preferably metal or non-metallic sheet material substrate at the particle tips by electrostatic deposition and for aligning a plurality of particles with their major axes aligned normal to the substrate and oriented tip-to-tip. Particles deposited form a low density, high relative void deposition to minimize attractive forces between the particles. This minimizes agglomeration and bonding forces to the substrate facilitating the release of a powdered medicament in an inhaler. Medicament dosages in a substrate pocket are covered by a sealing layer. An embodiment of a drug dosage inhaler substrate and inhaler is disclosed.</p> |
