PROBLEM TO BE SOLVED: To provide anα-crystal form of perindopril tert-butylamine salt, a method for producing the same, and a medicinal composition including the same. SOLUTION: Theα-crystal form of the compound represented by formula (I) shows a characteristic powder X-ray diffraction pattern. This compound has useful properties, for example, permitting easy filtration, drying and easy formulation thereby achieving the completely reproducible process for producing the crystal form. This method is useful for producing medicines. COPYRIGHT: (C)2005,JPO&NCIPI |
