    摘要: The invention provides the process for the preparation of pitavastatin and its pharmaceutically acceptable salts thereof. In particular, the invention provides a process for the preparation of stable pitavastatin calcium in crystalline form having water content less than 5% wt/wt. The present invention also provides stable crystalline form of pitavastatin calcium substantially free from crystal Form-A and use thereof for pharmaceutical compositions.

    摘要: A process of manufacturing of Rosuvastatin Potassium of formula (I) is disclosed. The process comprises the steps of (a) treating Rosuvastatin protected compound of formula (II) wherein R1 and R2 are same or different having C1-C4 carbon atom or hydrogen or R1 and R2 can combine together to afford a cyclic structure comprising a junction atom as carbon or metal atom such as Si (silicon); with an inorganic base of the kind such as herein described having potassium as cation in a suitable solvent to form Rosuvastatin potassium; (b) isolating Rosuvastatin potassium.
