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. The present invention also provides a method for treating these diseases employing the solid pharmaceutical dosage forms and a method for preparing the pharmaceutical dosage forms.

Compositions and methods for treating osteoporosis using the compositions are disclosed where the compositions have reduced GI toxicity and improved bio-availability and include a bisphosphonate and zwitterionic phospholipid.

The present invention provides novel bisphosphonate conjugates, pharmaceutical compositions comprising bisphosphonate conjugates and methods of using such analogs in the treatment of bone cancer, bone-related diseases and diseases of the soft tissues surrounding bones.

Oral dosage forms comprising risedronate or a salt thereof, a chelating agent, and means for effecting delayed release of the risedronate (or salt) immediate release of the oral dosage form to the small intestine of the mammal subject and pharmaceutically effective absorption of the bisphosphonate with or without food or beverages. The present invention substantially alleviates the interaction between the risedronate (or salt) and food or beverages, which interaction results in the active ingredient not being available for absorption. The resulting oral dosage form may thus be taken with or without food. Further, disclosed is delivery of risedronate and the chelating agent to the small intestine, substantially alleviating the upper GI irritation associated with bisphosphonate therapies. These benefits simplify previously complex treatment regimens and can lead to increased patient compliance with bisphosphonate therapies.
