Abstract

Det beskrives en fremgangsmåte for fremstilling av krystaller av legemiddelaktivbestanddel hvis gjennomsnittlige partikkelstørrelse ligger innen et på forhånd gitt område og hvis maksimale partikkelstørrelse ikke overskrider en på forhånd gitt verdi, hvorved en overmettet oppløsning under krystalliseringen underkastes en våtoppmaling ved hjelp av en innretning for våtoppmaling, hvorved det oppnås en primærkornsuspensjon.Det beskrives videre de krystaller som oppnås ved denne metode samt farmasøytiske formuleringer inneholdende krystallene.
