Delta crystalline form of the arginine salt of perindopril, a process for its preparation, and pharmaceutical compositions containing it

摘要

Delta crystalline form of perindopril L-arginine salt (I) having X-ray powder diffraction peaks measured using a diffractometer with a copper anticathode and expressed in terms of Bragg's angle 2 theta values as given in the specification, is new. Independent claims are included for: (1) the preparation of delta crystalline form of (I); and (2) a composition comprising an active agent and the delta crystalline form of (I) in combination with carriers. ACTIVITY : Cardiovascular-Gen; Hypotensive; Cardiant; Vasotropic. MECHANISM OF ACTION : Angiotensin I converting enzyme inhibitor.
