Abstract:
The present invention relates to new polymorphic forms of Crystalline Rosuvastatin calcium along with novel processes for crystalline as well as amorphous Rosuvastatin calcium.

Claim (Index 12):
A novel process for the preparation of Amorphous Rosuvastatin calcium using Form M2 of  claim 11 , which comprises\n i. Charging of crystalline form M2 of 7-[4-(4-flurophenyl)-6-isopropyl-2-(N-methyl-N-methylsulfonylamino)-pyrimidin-5-yl]-(3R,5S)-dihydroxy-hept-6-enoic acid Calcium salt or Rosuvastatin calcium in water (5-10 times). ii. Stirring at 30-35\u00b0 C. for 30-60 minutes. iii. Isolation of amorphous Rosuvastatin calcium by routine filtration & drying at 50-60\u00b0 C.
