  • Ezetimibe polymorphs
    Publication number: 20060160785
    Abstract: Provided are processes for preparing crystalline forms of ezetimibe, such as ezetimibe Form A or Form B, for example, by precipitating ezetimibe from selected solvents. Alternatively, some forms may be transformed into different forms at elevated temperatures or under various humidity conditions, or by micronization. Also provided are micronized ezetimibe Form A, micronized ezetimibe Form B, and ezetimibe having a plate morphology. Pharmaceutical compositions containing these forms are particularly useful in reducing cholesterol in patients in need thereof.
