NOVEL POLYMORPHIC FORMS OF PERINDOPRIL (L)-ARGININE AND PROCESS FOR THE PREPARATION THEREOF

摘要

The present invention relates to novel and stable polymorphic forms of Perindopril (L)-Arginine designated as Formγand amorphous form and processes for their preparation. The present invention also provides the novel polymorph Formγwith greater stability to heat and humidity and can be prepared on large scale by an efficient, economic and reproducible process.
