Abstract
The invention relates to a novel process for preparing crystalline ciclesonide with an advantageous particle size and to the use for producing pharmaceutical preparations, in particular for topical use. The crystalline ciclesonide obtained by the novel process has advantageous aerodynamic properties, and can be further processed to inhalable or nasally administered pharmaceutical preparations without further mechanical micronization.
