The process for making steroid crystals having a predetermined average particle size of from 1 mum to 25 mum and a maximum particle size that does not exceed a predetermined maximum value of 100 mum, includes subjecting a supersaturated solution containing a steroid to a wet milling by wet milling apparatus while crystallizing, in order to obtain a primary particle suspension. Crystals obtained according to this process and pharmaceutical preparations containing them are also described.
