FIELD: pharmaceutical technology, pharmacy, steroids.
SUBSTANCE: invention describes a method for preparing steroid crystals showing the mean coarseness in desired limits from 1 to 25 mcm and without exceeding the required value. Method for preparing involves wetted grinding a steroid supersaturated solution in the crystallization process by using a device for carrying out this process resulting to preparing suspension of primary grains followed by its heating. Also, the claim describes crystals prepared by the proposed method and pharmaceutical composition containing these crystals based on steroid crystals.
EFFECT: improved preparing method.
