ABSTRACT:
A therapeutic dry powder preparation and a method of administering such a preparation are disclosed for effectively de-aggregating and dispersing into air a dose of medication powder in an administration the dose to a user. The present dry powder preparation and method do not require other sources of energy besides the power of an inhalation effort by a user to produce a very high degree of de-aggregation and efficient dispersal into air of the dry powder medication dose. Utilizing an effort of sucking air through a nozzle, the particles of the therapeutic powder dose, made available to the nozzle, are gradually de-aggregated and dispersed into a stream of air entering the nozzle. The gradual de-aggregation and dispersal is produced by an air-razor effect due to a relative motion introduced between the nozzle and the powder dose
