Process for production of crystals of an adjuvant substance, crystals obtained thereby and pharmaceutical preparations containing them |
摘要 |
The process for making crystals of an adjuvant substance for pharmaceutical compositions, which have a predetermined average particle size in a predetermined size range and a maximum particle size that does not exceed a predetermined maximum value, includes subjecting a supersaturated solution containing the adjuvant substance to a wet milling by a 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.
