  • Patent number: 8927504
    Abstract: The present invention provides a novel therapeutic or preventive method, a pharmaceutical composition and use thereof, that exhibit superior anti-obesity effects (body weight-reducing (losing) effects and/or body fat mass-reducing effects). Specifically, the present invention provides a pharmaceutical composition comprising the combination of a dipeptidyl peptidase 4 inhibitor and a sweetener having a GLP-1 secretion-stimulating action, as well as use thereof for the manufacture of a medicament. The present invention also provides a method for treating or preventing obesity, comprising administering an effective amount of (a) a dipeptidyl peptidase 4 inhibitor and (b) a sweetener having a GLP-1 secretion-stimulating action to a patient suffering from symptoms of obesity.

  • Patent number: 7030120
    Abstract: Disclosed are compounds represented by formula (I) which have triglyceride biosynthesis inhibitory activity in the liver and inhibitory activity against the secretion of apolipoprotein B-containing lipoprotein from the liver and particularly have excellent inhibitory activity against the secretion of apolipoprotein B-containing lipoprotein, are free from side effect of accumulation of lipids in the liver, and are useful for the treatment and prevention of hyperlipidemia and arteriosclerotic diseases.

  • Patent number: 6583144
    Abstract: Disclosed are compounds represented by formula (I) and pharmaceutically acceptable salts and solvates thereof. The compounds can inhibit the biosynthesis of triglycerides in the liver and can inhibit the secretion of lipoprotein containing apolipoprotein B from the liver. Therefore, they are useful for the prevention or treatment of hyperlipidemia (particularly hyper-very-low-density-lipoproteinemia) and arteriosclerotic diseases, such as cardiac infarction, or pancreatitis induced by hyperlipidemia.

  • Patent number: 6440951
    Abstract: Fosfomycin or a pharmaceutically acceptable salt thereof has been found to have an action of lowering the serum glucose level and is recognized to be useful as an orally administrable remedy for treating diabetes. It has further been found that the serum glucose level-lowering action of fosfomycin or its salt can be enhanced synergistically and significantly when forfomycin is administered in association with vanadyl sulfate and the like. Therefore,the composition comprising fosfomycin or its salt and vanadyl sulfate or the like is useful as an orally administrable remedy for treating diabetes.
