Latest Patents

Among his latest patents is a process for the preparation of amorphous calcium salt of atorvastatin. This innovative process involves creating a reaction mixture with a pH between 6.5 and 8.0, which contains a sodium salt of atorvastatin and tetrahydrofuran. The method includes the addition of a non-cyclic chlorinated organic solvent, such as dichloromethane or chloroform, or a cyclic hydrocarbon solvent like cyclohexane. An equivalent or excess quantity of a source of calcium ions, such as calcium acetate or calcium chloride, is then added. The result is the isolation of amorphous atorvastatin calcium from the organic phase.

Another patent focuses on the preparation of amorphous atorvastatin calcium without the intermediate isolation of crystals. This process utilizes a mixture of chlorinated organic solvents or cyclic hydrocarbon solvents, along with water, to form calcium atorvastatin salt.
