  • 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.
