| Zusammenfassung: | The invention relates to a process for the preparation of amorphous atorvastatin calcium by recrystallization of crude atorvastatin from an organic solvent which comprises dissolving crude amorphous atorvastatin calcium in a lower alkanol containing 2-4 carbon atoms or a mixture of such alkanols under heating and isolating the amorphous atorvastatin calcium precipitated after cooling. The atorvastatin calcium obtained is a known valuable agent useful in treating hyperlipidemia and hypercholestrolemia. |
