Process for the preparation of amorphous atorvastatin calcium |
| abstract |
A process for the preparation of amorphous atorvastatin calcium and hydrates thereof, which comprises: (a) hydrolysis of the precursor lactone using sodium hydroxide to form atorvastatin sodium salt solution; (b) addition of the atorvastatin sodium salt solution to a calcium chloride or calcium acetate solution in the absence or presence of seeds of amorphous atorvastatin calcium; and (c) isolation of the resultant amorphous atorvastatin calcium salt by filtration and drying. |
