Beschreibung
Zusammenfassung:	The invention relates to a method of producing hollow, microporous particles which are intended, in particular, to be inhaled or for any other application. The inventive method consists in: providing a composition, in a given form, comprising at least one active principle and at least one blowing agent; cooling the aforementioned composition to below the solidification point of said at least one blowing agent so as to increase the volume of the given form and to create ruptures in the surface and/or in all of said given form, thereby enabling the structure of the hollow, microporous particle to be obtained; and removing all or part of said at least one blowing agent.
