Abstract: This invention relates to a pharmaceutical composition which is suitable for the administration of medicaments by inhalation. In particular, the pharmaceutical composition comprises microfine particles of medicament and at least one lactose pellet having a diameter of from about 10 to about 1500 micrometers, which pellet comprises a plurality of microfine lactose particles. A method of treating respiratory disorders which comprises administration by inhalation of an effective amount of medicament selected from the group consisting of anti-allergics, bronchodilators, anti-inflammatory steroids and mixtures thereof in the pharmaceutical composition as defined is described also.

Abstract: An air filter cabinet designed for a relatively large electronic air filter cells is adapted to receive and position a relatively smaller filter element without an associated loose fitting relationship and air leakage. A plurality of S-shaped adaptor elements are each removably interconnected to a respective guide rail in the cabinet to reduce the size of a cavity so as to accommodate the smaller filter element and secure it in a fixed position while preventing air leakage therearound.
