First Crystal Structures of the Antihypertensive Drug Perindopril Erbumine: A Novel Hydrated Form and Polymorphs α and β

The first crystalline structures of the antihypertensive drug perindopril unveiled by single crystal X-ray diffraction are reported herein. Structures of forms α and β of perindopril erbumine have been determined. A novel perindopril erbumine hydrated form was also synthesized and fully characterized.
