  • Publication number: 20100099621
    Abstract: The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than the corresponding monosodium salt. Furthermore, the inventors have discovered that the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. The delivery agents have the formula wherein R1, R2, R3, and R4 are independently hydrogen, halogen, C1-C4 alkyl, or C1-C4 alkoxy; and R5 is a substituted or unsubstituted C2-C16 alkylene, substituted or unsubstituted C2-C16 alkenylene, substituted or unsubstituted C1-C12 alkyl(arylene), or substituted or unsubstituted aryl(C1-C12 alkylene). The hydrates and solvates of present invention also have surprisingly greater efficacy for delivering active agents, such as heparin and calcitonin, than their corresponding monosodium salts and free acids. The present invention provides an alcohol solvate, such as ethanol solvate, of a disodium salt of a delivery agent of the formula above.

  • Publication number: 20090281064
    Abstract: The present invention provides novel solid pharmaceutical dosage forms for oral administration comprising a bisphosphonate, or a pharmaceutically acceptable salt thereof, which bisphosphonate is present in an amount not therapeutically effective when the bisphosphonate is orally administered alone, and a modified amino acid carrier, or a pharmaceutically acceptable salt thereof, which modified amino acid carrier is present in an amount effective to facilitate absorption of the bisphosphonate in the gastrointestinal tract such that the bisphosphonate is therapeutically effective. The ratio of bisphosphonate to modified amino acid carrier is from about 1:30 to about 1:1, respectively. These novel solid pharmaceutical dosage forms are useful in the treatment or control of bone diseases and particular disorders in calcium metabolism, including, for example, osteoporosis, hypercalcaemia of cancer, and the treatment of metastatic bone pain.

  • Publication number: 20090253614
    Abstract: Methods for treating impaired glucose tolerance and early and late stage diabetes in mammals, for prophylactically sparing ?-cell function, aiding in preventing ?-cell death, preventing the onset of overt diabetes in a mammal with type 2 diabetes, treating the current level of glycemic control dysfunction of a mammal with impaired glucose tolerance or diabetes, comprising orally administering insulin and a delivery agent that facilitates insulin absorption from the gastrointestinal tract at the time of or shortly before mealtime, e.g., within about 10 minutes prior to ingestion of a meal, on a chronic basis. The methods also comprise, in addition to administering a rapid-acting insulin to provide a first insulin peak, administering a slow acting insulin to provide a second insulin peak occurring at a later time but of a longer duration.
