  • Novel crystal forms of atorvastatin hemi-calcium and processes for their preparation as well as novel processes for preparing other forms
    Publication number: 20050261361
    Abstract: The present invention provides novel forms of atorvastatin designated Forms VI, VIII, IX, X, XI and XII and novel processes for their preparation as well as processes for preparing atorvastatin Forms I, II, IV, V and amorphous atorvastatin.
    Type: Application
    Filed: July 29, 2005

  • Processes for desolvating solvates of atorvastatin hemi-calcium and atorvastatin hemi-calcium essentially free of organic solvent
    Publication number: 20030216584
    Abstract: The present invention provides processes for removing organic solvent from crystals of atorvastatin hemi-calcium containing organic solvent. In one process, the organic solvent is displaced by vapor diffusion of water in a vessel maintained at elevated humidity. In a second process, the organic solvent is removed by fluidized bed drying. The present invention further provides atorvastatin hemi-calcium containing 1% or less organic solvent, which can be obtained from atorvastatin hemi-calcium that has been crystallized from an organic solvent-containing solution by practice of the processes of the invention.
