  • Paricalcitol purification
    Patent number: 8013176
    Abstract: Paricalcitol, a synthetic vitamin D analog, is purified to a purity greater than 99.7% by crystallization from solution in isopropyl acetate solvent, followed by filtration and vacuum drying. Isopropyl acetate appears to be unique among commonly available and pharmaceutically acceptable solvents in its ability to precipitate paricalcitol in this high purity, essentially free of isomers thereof. In addition, paricalcitol of purity of at least 99.9% has been shown to have exceptional storage stability.
    Type: Grant
    Filed: August 19, 2009
    Date of Patent: September 6, 2011
    Assignee: Alphora Research Inc.
