  • Patent number: 7144873
    Abstract: Pharmaceutical formulations, kits and vessels are provided for delivering decitabine to a patient suffering from a disease in need of treatment with decitabine. The pharmaceutical formulation comprises decitabine solvated in a non-aqueous solvent that comprises glycerin, propylene glycol, polyethylene glycol, or combinations. Such formulations are more chemically stable than conventional liquid formulations of decitabine containing more than 40% water in volume. The pharmaceutical formulations can be used for any disease that is sensitive to the treatment with decitabine, such as hematological disorders and cancer.
    Type: Grant
    Filed: July 13, 2004
    Date of Patent: December 5, 2006

  • Publication number: 20040167205
    Abstract: A method is provided for preparing a pharmaceutical composition comprising: taking polyoxyethylated castor oil which if diluted 1:10 in water has a pH greater than 5 and aging the polyoxyethylated castor oil by exposing the polyoxyethylated castor oil to a gas comprising oxygen for a period of time, the exposure to the gas over the period of time causing an acidity of the polyoxyethylated castor oil to increase; and forming a pharmaceutical composition comprising the aged polyoxyethylated castor oil and a pharmaceutically active agent such as paclitaxel; wherein at least 80% of the potency of the pharmaceutically active agent is retained by the pharmaceutical composition after the pharmaceutical composition is stored for at least 7 days at 40° C.
