Novel polymorphic forms of Perindopril (L)-Arginine and process for the preparation thereof

摘要

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