  • Patent number: 6034085
    Abstract: The crystalline, stable methanesulfonate salt of nefazodone showed significantly higher intrinsic dissolution in water and THAM buffer (pH 7.5) compared to other salts of nefazodone. The faster dissolution rate of this salt at neutral pH suggests better dissolution and absorption in the intestine, allowing controlled release of nefazodone for oral formulations.

  • Patent number: 5880106
    Abstract: Improved oral dosage formulations for acid-labile dideoxy purine nucleoside derivatives such as ddA, ddI, and ddG, have been developed by incorporating selected water-insoluble buffering systems in the formulation. These novel formulations provide reduced mass dosage units in the form of convenient, palatable chewable/dispersible tablets or a dry powder sachet. The reduced mass requirement, necessary to allow tablets of reasonable size, was achieved in part by an unexpected 20 to 25% increase in drug bioavailability resulting from use of the selected buffering systems comprised of an insoluble magnesium antacid agent and either dihydroxyaluminum sodium carbonate or calcium carbonate.
