DH Novel Polymorphic DH Form of Aripiprazole Anhydride and Preparing Method of the Same

摘要

The present invention relates to novel polymorphism of aripiprazole, which are DH-1, DH-2, and DH-3. The present invention further relates to a method for producing the polymorphism. The novel polymorphism of aripiprazole provided in the present invention ensures excellent physicochemical properties such as stability and non-hygroscopicity, and can be useful for producing aripiprazole-containing drugs.
