Abstract

A találmány tárgya bevont, gömbölyű granulátumszemcsék (pelletek)előállítására alkalmas eljárás, amelyre jellemző, hogy a) forgóágybanvagy folyóágyban hatóanyagot tartalmazó nyers pelletekre, amelyeklegalább egy gyógyászati hatóanyagot és adott esetben gyógyászatilagelfogadható segéd- és/vagy hordozóanyagokat foglalnak megukban,adalékokat is tartalmazó polimerdiszperziót porlasztanak, amelydiszperzió polimerként etilcellulózt és/vagy poli(met)akrilsavészterttartalmaz, <) a polimerdiszperziót olyan vastagságban viszik fel,amely a teljes tömeg 1-5 tömeg/tömeg%-át képezi, ahol az összetételteljes tömege a bevont pellet tömegét jelenti, g) a polimerrel bevontpelleteket 45°C és 65°C közötti hőmérsékleten temperálják, d) apolimerrel bevont pelletek temperálását legalább 24 órán át végzik ése) a gyógyászati hatóanyag prosztán-származék.
