Beschreibung
Zusammenfassung:	The present invention relates to hydroxypropyl methylcellulose phthalate (HPMCP) particles having a porous particle shape and a method of preparing the same. The preparation method includes (1) preparing an HPMCP reaction solution; (2) adding water to a stirring tank including a stirring device such that the stirring device is immersed therein; (3) dropping the HPMCP reaction solution into the stirring tank; and (4) adding the dropped HPMCP reaction solution to water contained in the stirring tank, in which the stirring device is operating, to be granulated while moving along the flow of the water. In accordance with the present invention, the HPMCP reaction solution is added to water contained in the stirring tank, in which the stirring device is operating, to granulate the HPMCP, whereby porous HPMCP particles can be prepared. Accordingly, the solubility of the particles can be improved.
