<p>Inhalation Apparatus In an inhalation apparatus for the inhalation of pulverulent material, especially micronised pharmaceutical compositions from capsules, a chamber (6) for receiving the capsules is provided, which has an internal width about 1.1 to 2.5 times the capsule diameter and an internal length of at least about 1.02 and less than 2.0 times the length of the capsule and which comprises at one narrow end an air inlet (3) and at the other end an air outlet, so that during inhalation through the inhalation apparatus the capsule is set in vibration providing enhanced expulsion and fragmentation of the pulverulent material.</p> |
