  • Patent number: 8828438
    Abstract: A solid amorphous dispersion comprises a cholesteryl ester transfer protein (CETP) inhibitor, an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase inhibitor), and a concentration enhancing polymer. At least a major portion of the CETP inhibitor in the dispersion is amorphous. The solid amorphous dispersion provides concentration-enhancement of the CETP inhibitor when administered to an aqueous use environment.

  • Publication number: 20110002989
    Abstract: The present invention provides methods, dosage forms and kits for treating with an effective amount of ziprasidone a CNS disorder in a human when the human is in a fasted state. In one embodiment, the invention relates to a method for treating a CNS disorder in a human, which method comprises administering to the human in a fasted state, a solid oral dosage form comprising an amount of ziprasidone effective to treat said CNS disorder, wherein the area under the serum concentration versus time curve (AUC0-inf) of the ziprasidone in the human subsequent to said administering is from 70% to 140% of the mean area under the ziprasidone serum concentration versus time curve (AUC0-inf) resulting from administration of a control ziprasidone immediate release oral capsule containing the same amount of ziprasidone to a cohort of humans in a fed state.
