PROCESS FOR PREPARING CRYSTALLINE CICLESONIDE WITH DEFINED PARTICLE SIZE

摘要

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