Abstract (en)
[origin: WO03090721A2] The invention relates to a method for producing crystallines from active ingredients in medicaments, the average particle size thereof lying within a given range and the maximum particle size thereof not exceeding a given value. During crystallisation, an oversaturated solution is subjected to wet milling by means of a wet milling device; as a result, a primary grain suspension is obtained. The invention also relates to crystals obtained according to said method and pharmaceutical formulations containing said crystals.
